BMST Earth's Geological Cycles 2

Question 1

Which type of rock is formed when magma cools and solidifies below Earth's surface?

Accepted Answer

Intrusive igneous

Answer

Intrusive igneous rocks form when magma solidifies slowly beneath Earth's surface, producing coarse-grained rocks like granite.

Question 2

During the water cycle, what process converts liquid water into water vapor?

Accepted Answer

Evaporation

Answer

Evaporation is the process by which liquid water absorbs heat energy and transforms into water vapor at the surface.

Question 3

Which layer of Earth is responsible for the movement of tectonic plates?

Accepted Answer

Asthenosphere

Answer

The asthenosphere is a semi-fluid layer of the upper mantle that flows slowly, driving the movement of tectonic plates above it.

Question 4

What is the primary source of energy that drives the water cycle?

Accepted Answer

Solar energy

Answer

Solar energy from the Sun powers evaporation, which is the first step in the water cycle.

Question 5

When two oceanic tectonic plates converge, what typically occurs?

Accepted Answer

One plate subducts beneath the other

Answer

When two oceanic plates converge, the denser plate subducts under the less dense plate, often forming deep ocean trenches.
