Amplify- Rock Transformations Chapter 3 Flashcard

Front

What do sediments represent in the rock cycle?

Back

Sediments represent the small particles that accumulate and can eventually form sedimentary rocks through processes like compaction and cementation.

Front

What is compaction in the context of sedimentary rocks?

Back

Compaction is the process by which sediments are pressed together under pressure, reducing their volume and leading to the formation of sedimentary rock.

Front

Where are the oldest layers of sedimentary rock typically found?

Back

The oldest layers of sedimentary rock are typically found at the bottom of a rock formation.

Front

What is the role of uplift in the rock cycle?

Back

Uplift is the process that brings rocks from deep within the Earth to the surface, exposing them to weathering and erosion.

Front

What is subduction in geological terms?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, which can lead to the transformation of rocks.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces due to environmental factors like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which weathered rock and soil are moved from one location to another, often by water, wind, or ice.

Front

What are the three main types of rocks?

Back

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

Front

What is an igneous rock?

Back

Igneous rock is formed from the cooling and solidification of magma or lava.

Front

What is a metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that are transformed by heat, pressure, or chemically active fluids.
