Geologic Processes Flashcard Review

Front

What is a transform boundary?

Back

A transform boundary is a type of tectonic plate boundary where two plates slide past each other horizontally, often causing earthquakes.

Front

What is a subductive boundary?

Back

A subductive boundary is a tectonic plate boundary where one plate is forced under another, leading to volcanic activity and earthquakes.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How do igneous rocks form?

Back

Igneous rocks form from the cooling and solidification of molten rock (magma or lava).

Front

What is the role of temperature in rock formation?

Back

Temperature affects the state of rocks; high temperatures can melt rocks into magma, while lower temperatures allow them to solidify.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is the mantle?

Back

The mantle is the thick layer of rock between the Earth's crust and outer core, where convection currents occur.

Front

What causes volcanic eruptions?

Back

Volcanic eruptions are caused by the movement of magma from the mantle to the surface, often due to pressure build-up.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the Earth's surface, while lava is magma that has erupted onto the surface.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces like wind, water, and temperature changes.
