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).

Answer:

A) the level of cyanide in the bamboo population will increase

Explanation:

Final answer:

A lemur species that consumes bamboo shoots high in cyanide has developed a tolerance through evolutionary adaptation, and this trait could become more refined over generations, improving the species' survival prospects.

Explanation:

In the instance of a lemur species that eats only bamboo shoots, which are high in cyanide, selective pressures favor individuals with a tolerance for cyanide. Over time, if this trait is beneficial to the lemurs' survival and reproduction, we would expect the species to exhibit increased genetic resistance to cyanide toxicity. This phenomenon is an example of evolution through natural selection, where the genetic makeup of a population changes as members with beneficial traits survive to pass those traits on to offspring.

Metabolic adaptations enable species like bamboo lemurs to process toxic substances that would otherwise be harmful. Through the process of evolutionary adaptation, these lemurs have developed the ability to metabolize cyanide. If these lemurs continue to thrive on a diet containing cyanide, it suggests that their detoxification mechanisms are effective and will likely become more refined over generations. Such adaptations diminish the impact of potential predators, as the presence of toxic substances within the lemurs' bodies can deter predation.

It's important to note that evolutionary changes take time and occur over many generations. Should the environment remain relatively stable, it is probable that the lemurs' tolerance to cyanide will solidify as a key feature of the species, potentially leading to other, secondary adaptations as they continue to exploit a dietary niche that is inaccessible to other animals without this unique tolerance.

In this case, Ithilium produces more electronics than Kilim even both countries use the same amount of electricity.

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.

As 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.

This is why plants in high latitudes receive less direct solar energy over the course of the year compared to plants closer to the equator.

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.

(c) in some parts of its orbit it is much closer to the Sun than in other.

When a planet has a highly eccentric orbit, it means that its orbit is an ellipse with the Sun at one focus. In some parts of its orbit, the planet is much closer to the Sun than in others.

When we say that a planet has a highly eccentric orbit, it means that its orbit is an ellipse with the Sun at one focus. In other words, the planet's orbit is stretched out into an elongated shape.

The eccentricity of an orbit describes how elongated or circular it is. If a planet has a highly eccentric orbit, it means that there is a significant difference in its distance from the Sun at different points in its orbit. In some parts of its orbit, the planet will be closer to the Sun, while in other parts it will be farther away.

For example, Pluto has a highly eccentric orbit. At some points in its orbit, it is much closer to the Sun than at others.

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.

Option (D)

Explanation:

Constellation usually refers to the group of stars that forms a particular feature in the sky and which is visible at night. This is visible when the earth is located at the exact position from which it can be viewed. It often helps in the identification and location of the stars in space.

These constellations are visible from the earth when viewed in the evening, but only at particular times in a year. It is because the earth keeps on changing its position with respect to the sun. The earth goes around the sun in an elliptical orbit, and only at a few positions, with favorable conditions such as clear sky, these constellations are visible.

Thus, the correct answer is option (D).

Final answer:

Constellations are only visible during certain seasons because our view of space at night depends on Earth's position in its orbit around the Sun.

Explanation:

In any particular place on Earth, certain constellations are visible in the evening only at certain times of the year because our evening view of space depends on where Earth is located in its orbit around the Sun. As the Earth revolves around the Sun, the night sky changes, making different constellations visible at different times. In winter, for example, we can see constellations like Orion, while in summer, these constellations are not visible at night, because they are in the daytime sky, near the Sun.

The rotation and revolution of Earth cause various astronomical phenomena such as the changing visibility of constellations, the northern and southern circumpolar zones, and the unique experiences of star visibility at different latitudes. Therefore, the answer to the student's question is (D).

Stars and constellations that are circumpolar remain visible all year round for observers at certain latitudes. At the North Pole, for example, one would see certain constellations like the Big Dipper circle the sky parallel to the horizon, while others will never rise above the horizon. Similarly, at the equator, the celestial equator passes through the zenith, and stars rise and set perpendicular to the horizon.

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.

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.

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.

How far north you live from the equator is measured as your latitude, whereas an imaginary line marking all those places at that same distance north of the equator is called a parallel. Latitude is a geographical coordinate that specifies the north-south position of a point on the Earth's surface. It ranges from 0 degrees at the equator to 90 at the poles. On the other hand, parallels are imaginary lines running east-west around the globe, parallel to the equator, that indicate latitude.
