What is a tectonic plate?

A tectonic plate (also called a lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.

Why does Earth have tectonic plates?

Without plate tectonics, our planet would be a very different place. The constant recycling of the Earth's crust provides us with a stable climate, mineral and oil deposits, and oceans with a life-sustaining balance of chemicals. It even gives evolution a kick every few hundred million years.

The layer of Earth that is under the Crust is called the Mantle - so the statement is correct. Crust is the solid shell on which we live and it's a lot thicker under the land than under the oceans.

Mantle is fluid in contrast to the Crust - so the Crust can be said to float over the mantle.

Explanation:

The faster an igneous rock cools, the ____ its crystals will be.-more colorful
-more irregular
-larger
-smaller

Answers

The correct answer is - smaller.

The size of the crystals of the igneous rocks is directly affected by the speed of the cooling of the magma.

If the magma cools off very quickly, than the size of the crystals of the igneous rocks will be very small, while if the magma cools off very slowly, than the size of the crystals of the igneous rocks will be bigger.

This happens because of the time of influence of other factors in the formation of the rock itself. The ones that are on the surface or close to it, cool off very quickly, so there's no time for any significant influences on the rock. The ones that are deeper into the ground, cool off much slower because it is hotter, and also in that period the temperature and the high pressure manage to heavily influence the rock, thus making it having bigger crystals.

Smaller. The longer time it has to cool down, the bigger it will get. In this case, since it is cooling faster, the rock will be smaller.
