Geology- Layers Plates and Rocks

Front

What is a Divergent Boundary?

Back

A boundary where tectonic plates move apart, creating rift valleys, seafloor spreading, and underwater mountain chains.

Front

What type of rock is formed from the melting and cooling of magma?

Back

Igneous rock.

Front

What are Convection Currents?

Back

The process in the mantle that moves Earth's plates, where heat rises and then cools and sinks.

Front

What type of rock forms from extreme heat and pressure?

Back

Metamorphic rock.

Front

What processes can turn metamorphic and igneous rocks into sedimentary rocks?

Back

Compacting and Cementation.

Front

What is a Convergent Boundary?

Back

A boundary where tectonic plates collide, often forming mountains or causing earthquakes.

Front

What is a Transform Boundary?

Back

A boundary where tectonic plates slide past each other, leading to earthquakes.

Front

What is Sedimentary Rock?

Back

Rock formed from the accumulation and compaction of mineral and organic particles.

Front

What is the Rock Cycle?

Back

The continuous process of rock formation and transformation between igneous, sedimentary, and metamorphic rocks.

Front

What is the Earth's Mantle?

Back

The layer of the Earth between the crust and the core, involved in convection currents.
