Earth Science Study Guide - Plate Boundaries and Processes

Front

What is liquefaction?

Back

Liquefaction is a process that occurs during an earthquake when solid ground saturated with water turns into a liquid-like state due to shaking.

Front

How is metamorphic rock formed?

Back

Metamorphic rock is formed by heat and pressure on existing rocks, resulting in a foliated or non-foliated texture.

Front

What type of plate boundary is associated with the formation of a rift valley and lake?

Back

Divergent (continental/continental) boundaries are associated with the formation of a rift valley and lake.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is a boundary at which two tectonic plates move toward each other.

Front

Where can volcanoes occur?

Back

Volcanoes can occur at divergent boundaries, convergent boundaries, and over hotspots.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, often leading to the formation of new crust.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another plate and sinks into the mantle.

Front

What are the characteristics of sedimentary rocks?

Back

Sedimentary rocks are formed by the deposition of sediments and are typically layered.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, including igneous, sedimentary, and metamorphic rocks.
