Sea stars are broadcast spawners: They release their gametes into the water without courtship. Which of these reproductive isolation mechanisms is most likely affecting sea stars?
a. behavioral isolation or mechanical isolation
b. gametic isolation or temporal isolation
c. habitat isolation
Answer:
b. gametic isolation or temporal isolation
Explanation:
Gametic isolation is a type of prezygotic barrier where the gametes (egg and sperm) come into contact, but no fertilization takes place.
Temporal isolation - separation in time such that reproduction occurs at different times of the day, or season or even years. For example, consider the time of day when Evening primrose or Morning glory flowers. The Western spotted skunk mates late summer, whereas the eastern spotted skunk mates in late winter.

Density is a key component in the behavior of Earth materials and is especially important in understanding important aspects of the plate tectonics model. Describe three different ways that density and/or density differences play a role in plate tectonics.
Answer:
Density is one of the most factors that play a key role in plate tectonic activities. Some of the ways in which density is important in the field of plate tectonics are as follows-
The convergent plate boundaries are responsible for the creation of a subduction zone, where the high-density lithospheric plate subducts below the less dense one. It is because the heavier plate is comprised of heavy minerals thereby forming heavier rocks as a result of which its density increases. Due to these differences in density, there occurs a subduction zone. The divergent plate boundary forms where two plates move away from one another. This type of plate motion is responsible for the eruption of magma on the seafloor. As the plates diverge, the lithosphere becomes eventually thin, and with more progressive spreading, the magma comes out to the seafloor. This is because the hot magma is less dense, and forms convection cells as they rise upward. This is how the density helps in the upwelling of magma at the mid-oceanic ridge in a divergent plate boundary. When there collide two plates of equal densities, then it gives rise to the formation of huge mountains, because neither of them is heavy to get sink. So it uplifts the crust, forming a sandwich-type pattern.The key component in the behavior of Earth materials is:

Read the article titled "Coastlines: Works in Progress." Using two or three sentences, describe the role of waves in shaping Earth's coastlines. (Site 1)
Answer: Waves through their nonstop action play a role in shaping the earth's coastline. This they achieve by their constant ability to move sands and gravel, breach barriers, build walls and even sculpt bays. As a result, no coastline ever remains the same for long.
Explanation: Coastlines are lines where land meets water. They constantly are changed and reshaped by waves built up by winds far out at sea, which unleash their energy when they break on the shore. They deliver sand and gravel to, move them along and also out of the beach.
This nonstop action means nothing ever stays the same. Breakers gnaw away at cliffs, shift sand to and fro, breach barriers, build walls, sculpt bays etc.
At an astronomical conference, an astronomer gives a report on a star that has recently begun to interest astronomers because of hints that it may have a planet around it. In his report the astronomer gives the average speed with which this star is moving away from the Sun. How did the astronomer measure this speed?
By looking at the Doppler shift in the lines of the star's spectrum. T/F
Answer:
True
Explanation:
Hello!
Doppler spectroscopy is a measurement system used to estimate the radial velocity of a star.
To make this measurement, a series of observations are made on the spectrum of light emitted by a star. Then, it is detected if the characteristic wavelengths of the light spectrum vary, which may indicate that the radial velocity of the star varies. This situation can be caused by the presence of planets in the orbit of that star.
If a planet is found, it can determine its mass by studying the combinations in the radial velocity of the star.

D.
The volcanic landforms at divergent ocean plate boundaries are _oceanic ridges____.
Explanation:
As two tectonic plates move away from each, they leave a vacuum in between the two plates. This vacuum is filled by upwelling magma from the mantle. As the upwelling magma cools it forms a mountainous ridge along the boundary – because the magma cools rapidly before it could spread further out on the surface. Examples of these landforms are the Mid-Atlantic Ridge and the East Pacific Rise located at divergent tectonic boundaries.

What was the main reason Wegener’s continental drift hypothesis was rejected? He could provide only illogical explanations for the movement of the continents. He was not well respected by other scientists. His evidence was incorrect. He could not provide a wholly acceptable explanation for the movement of the continents.
Wegener could not provide a wholly acceptable explanation for the movement of the continents.
Explanation:
Alfred Wegener is the person that developed and promoted the continental drift theory. Despite him having developed the basic idea behind the process, as well as managing to find several clues to support it, his ideas were not accepted by the other scientists and he found it extremely hard to gain support. The main reason as to why this was the case was that he didn't really had wholly acceptable explanation about the movement of the continents.
Everything that Wegener provided as evidence was correct, and it was proving a point. The problem was that he still lacked explanation for the driving force of this process, nor did he had any proof about it, and that was the basis for all other things. Every clue that he had was the final product, but no one could explain as to how that actually happened.

Wegener's continental drift hypothesis was rejected mainly because he could not provide a satisfactory explanation for how the continents moved. His suggestion that continents moved over time was unprecedented and lacked the support of a convincing underlying mechanism.
Explanation:The primary reason Wegener's continental drift hypothesis was rejected was that he could not provide a wholly acceptable explanation for the movement of the continents. Alfred Wegener, a German meteorologist, proposed the idea of continental drift in 1912, suggesting that continents moved across the surface of the Earth over thousands of years. However, he lacked a convincing mechanism to explain this movement. In Wegener's time, the scientific community did not have the advances of seabed mapping or the concept of sea-floor spreading that would later support the theory of plate tectonics. His proposal was thus met with significant skepticism, as he could not satisfactorily explain how the continents moved.

LATITUDES AND PARALLEL
Explanation:
Latitudes are the lines that are oriented in the east-west direction and are measured from the equator moving towards both the poles. It ranges from 0° to 90°, where 0° refers to the equator and 90° refers to both the poles on either side. This latitude together with the value of longitude gives the exact coordinates of a location on earth.
Parallels are the imaginary lines joining all the places lying on the same latitude. These are the lines oriented in the east-west direction. These lines are extended in both the hemisphere, maintaining a fixed distance from the equator.
The distance north you live from the equator is measured as your latitude, while the imaginary line running east-west at that same distance north from the equator is called a parallel.

If a single disturbance at an unknown distance emits both transverse and longitudinal waves that travel with distinctly different speeds in the medium, such as in the ground during an earthquake, how can the distance to the disturbance be determined?
Answer:
Explanation:
If the differences in the time of arrival of each wave is measured, the distance can be calculated. The more the difference in their time of arrival, the more the distance and this distance can be in any direction. If distance is used as the radius on the circle that will mean that the disturbance must have taken place on the circle.
If you place a telephone call to two people with similar measurements about this same event at different places, then their circles can be transfered to your own map, the point of intersection of this 3 circles is the location of disturbance.
Final answer:
To calculate the distance to the source of an earthquake, seismographs use the time difference between the arrival of P-waves and S-waves. The distance can be precisely determined given the speeds of these waves and the precision of timing measurement. Uncertainties in the wave speeds can affect the accuracy of this distance calculation.
Explanation:
To determine the distance to the disturbance, such as the epicenter of an earthquake, seismographs measure the arrival times of P-waves and S-waves with a high precision. Because these waves travel at different speeds through the medium, the time difference in their arrival can be used to calculate the distance to the source of the earthquake.
The formula for the distance D to the earthquake's epicenter is based on the measured time difference
Dt between the arrival of the P-waves and S-waves and their respective speeds Vp for P-waves and Vs for S-waves:
D = Vp * (Dt) / (1 - Vs/Vp)
Given the precision of time measurements (0.100 s) and the known speeds of P-waves (7.20 km/s) and S-waves (4.00 km/s), one can solve for D to find the distance to the epicenter with a certain level of precision. However, any uncertainties in the speeds of the seismic waves would contribute to a greater uncertainty in the determined distance.
In practical terms, this difference in arrival times provides a way to triangulate the location of an earthquake's epicenter or the site of underground nuclear detonations, which is crucial for geological studies and for monitoring compliance with test ban treaties.

Answer:
Option (C)
Explanation:
Coquina is usually defined as a sedimentary limestone rock that is found to be present in the freshwater zones and in the coastal areas. This rock is made up of broken shells that are smaller in size. The rocks can be easily broken down by the constant flowing of sea waves.
This rock is commonly formed in the same way as the other sedimentary rocks, i.e. it is formed by the deposition of sediments carrying these organic remains and eventually undergoes the process of compaction and lithification on the seafloor.
Thus, the correct answer is option (C).
The correct statement is that Coquina rock is a form of a sedimentary rock. So, the correct option matching the statement above is C.
Coquina rock is basically formed of chemical compositions and living organisms, which are mostly formed near marine bio-diversities and marine conditions.
Sedimentary rocks Sedimentary rocks refer to such rocks which are formed due to the deposition of multiple layer of mineral or dead organisms on the surface of the Earth. As it is known that Coquina is formed by the deposition of seashells near the oceans, it can be said that coquina rocks are also a form of sedimentary rocks.Hence, the correct option is C, that Coquina rocks are a form of sedimentary rock.

A. Divergence
B. Weathering
C. Sublimation
D. Subduction
Answer: Subduction
Explanation:
Because it was in the lesson
Answer:
Option (D)
Explanation:
Two plates move towards one another in the case of a convergent plate boundary. Due to this, a subduction zone is created, where the heavier crust sinks below the lighter one. This zone of subduction is commonly identified by the presence of a narrow V-shaped depression known as deep-sea trench.
As the subducting denser plate reaches the layer of the asthenosphere, the rocks undergo partial melting, and the melt produced from it mixes with the magma. This magma eventually moves upwards to reach the surface in the over-riding plate giving rise to the formation of volcanoes.
The subduction zone and the oceanic trench are two of the common features present in the convergent plate boundary.
Thus, the correct answer is option (D).

The GAIA spacecraft is capable of measuring parallax angles as small as about 0.00002 arcseconds (20 microarcseconds). Based on this fact, GAIA should in principle be able to measure the distances of stars located __________.
Answer:
It will be able to measure the distances of stars located across the Milky Way galaxy and outside it up to a distance of 50 Kiloparsec.
Explanation:
1 arcsecond is 1/parsec.
0.00002 arcsecond is 1/0.00002 parsec = 50,000 parsecs or 50 Kiloparsecs.
The shortest distance to the edge of the Milky Way is about 8 Kiloparsec and the farthest is about 24 Kiloparsec. So at this parallax angle, it can measure the distances of stars across the Milky Way galaxy. Any stars within a distance of 50 Kpc will be measured by GAIA. However, since the closest galaxy to the Milky Way is about 770 Kpc away, GAIA will be unable to measure any stars in another galaxy.
Final answer:
The GAIA spacecraft can accurately measure parallax angles as small as 20 microarcseconds, enabling measurement of stellar distances up to about 30,000 light-years away, far beyond the 300 light-year capability of its predecessor Hipparcos.
Explanation:
The GAIA spacecraft is an exceptional tool for measuring parallax angles to an incredible precision of about 20 microarcseconds, far exceeding the capabilities of its predecessor, Hipparcos. Given this precision, GAIA can measure the distances of stars much farther than ground-based observations could previously achieve. In particular, with an accuracy of a few microarcseconds, GAIA extends our ability to accurately measure stellar distances up to about 30,000 light-years away, covering nearly a third of the galactic disk. This is significantly further than the approximately 300 light-year extent possible with Hipparcos, illustrating GAIA's remarkable improvement in the field of astrometry.

True or false plants in a high latitude receive less direct solar energy during the year than plants at a lower latitude because they are farther from the equator
True. Plants in higher latitudes receive less direct solar energy throughout the year due to the curvature of the Earth and the angle at which sunlight reaches the surface.
Do plants in a high latitude receive less direct solar energy during the year than plants at a lower latitude because they are farther from the equatorAs you move towards higher latitudes from the equator, the angle at which sunlight reaches the Earth's surface becomes more oblique. This causes the same amount of solar energy to be spread over a larger area, leading to lower intensity of sunlight.
