The correct answer is - D. volcanic eruptions.

In recent studies and research about the water on our planet and how it came to be, the scientists managed to find new evidence that suggest that not only the comets and asteroids contributed to the existence of water on our planet, but also the volcanoes.

The volcanoes are actually releasing into the atmosphere the material from the deeper part of the Earth, the mantle layer. The mantle layer, as it turns out, has water in its rocks, so through the volcanic eruptions, that were much more and much bigger in the distant past, that water got released into the atmosphere. From the atmosphere, that water was falling on the surface, thus contributing to the creation of the first oceans on Earth.

Answer:

x −2 −1 1 2

y −4 −2 2 4

Explanation:

$x = -2,$ $y = -4$ → $k=\frac{-4}{-2} =2$

$x=-1,y=-2$ → $\frac{-2}{-1} =2$

$x=1,y=2$ → $k=\frac{2}{1} =2$

$x=2,y=4$ → $k=\frac{4}{2} =2$

This Table All has the same value of K

Hence, 3rd one also known as Table C represent a proportional relationship.

The quartz is more resistant to abrasion and chemically more resistant than the feldspar. The result is that the quartz remains in the stream but the feldspar breaks down to clay or is dissolved.

How do we know there is Dark Matter in other galaxies? a. it occasionally lum inesces b. flat rotation curves in spiral galaxies

lesantik [10]

Answer:

b. flat rotation curves in spiral galaxies

Explanation:

Dark matter accounts for majority of the matter in the universe (about 85%). It is considered to be composed of subatomic particles which are yet to be discovered. Dark matter cannot be observed because it does not emit light that can be detected. Only its gravitational effect is visible.

Astronomers when calculated the mass of the visible matter and tried to account for the observed speed of stars in the galaxy, there was a mismatch. To understand what caused this mismatch, astronomers gave name to the invisible matter as the Dark Matter.

The expected velocity of stars should decrease away from the near the center of the galaxy but a constant velocity of stars was observed that is a relatively flat rotation curve was obtained.

Thus, flat rotation curves in spiral galaxies in an evidence of Dark Matter.
