BMST - Basic Math and Science Earth's Geological Cycles Questions and Answers 2

Question 1

What type of rock is formed from cooled magma or lava?

Accepted Answer

Igneous

Answer

Igneous rocks form when molten rock (magma below surface, lava above) cools and solidifies.

Question 2

Which layer of the Earth is composed of liquid iron and nickel?

Accepted Answer

Outer core

Answer

The outer core is a liquid layer of iron and nickel that generates Earth's magnetic field.

Question 3

What drives the movement of tectonic plates?

Accepted Answer

Convection currents in the mantle

Answer

Heat from Earth's interior creates convection currents in the mantle that push and pull plates.

Question 4

What is weathering?

Accepted Answer

The breakdown of rocks by physical, chemical, or biological processes

Answer

Weathering breaks down rocks in place, while erosion transports the broken material.

Question 5

What is the rock cycle?

Accepted Answer

The continuous process of rocks transforming between igneous, sedimentary, and metamorphic types

Answer

The rock cycle describes how rocks change from one type to another through geological processes over time.
