Which action should you take?

Choose only one option

Perched aquifer

Aquifer

Confining layer

Confined aquifer

Question 2: In petrology, what is the primary difference between intrusive igneous rocks and extrusive igneous rocks?

Which action should you take?

Choose only one option

Extrusive rocks form from magma, while intrusive rocks form from lava

Intrusive rocks are formed from sediments, while extrusive rocks are volcanic

Intrusive rocks are darker in color, while extrusive rocks are lighter

Which action should you take?

Choose only one option

A boundary where the Earth's magnetic poles shift

A region where two tectonic plates collide, often forming mountains or subduction zones

A zone where tectonic plates slide past each other
