Balanced Biosphere Task 2 Explore Flashcard

Front

What is the second step in the formation of oil or natural gas?

Back

Fossils buried under sediment slowly change into kerogen.

Front

What type of plate boundary is formed when two tectonic plates collide?

Back

Convergent - Collision.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates move towards each other, often causing one plate to be forced below the other.

Front

What geological feature is commonly found at a divergent boundary?

Back

Rift Valley.

Front

What happens at a transform boundary?

Back

Two tectonic plates slide past each other horizontally.

Front

What is kerogen?

Back

A solid organic material that is a precursor to oil and natural gas.

Front

What is the role of heat and pressure in the formation of oil?

Back

Heat and pressure transform kerogen into oil and natural gas over millions of years.

Front

What is a subduction zone?

Back

A region where one tectonic plate moves under another, often leading to volcanic activity.

Front

What type of plate boundary is associated with volcanic arcs?

Back

Convergent - Subduction.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other, often creating new crust.
