What is a graben?

Back

A graben is a block of the Earth's crust that has dropped between two normal faults, characterized by a hanging wall that has moved down.

Front

What does orogeny refer to?

Back

Orogeny refers to the process of mountain building, typically associated with tectonic plate interactions.

Front

What type of fault has little to no vertical movement?

Back

A strike-slip fault has little to no vertical movement, primarily involving horizontal movement.

Front

Where are the Aleutian Islands located?

Back

The Aleutian Islands are located at a convergent boundary on a volcanic island arc above a northward subducting Pacific plate.

Front

What type of plate boundary is associated with rift valleys?

Back

Rift valleys are typically associated with divergent plate boundaries.

Front

Define a normal fault.

Back

A normal fault is a type of fault where the hanging wall moves down relative to the footwall, typically caused by extensional forces.

Front

What is a reverse fault?

Back

A reverse fault is a type of fault where the hanging wall moves up relative to the footwall, typically caused by compressional forces.

Front

Explain the concept of a tectonic plate.

Back

A tectonic plate is a massive slab of solid rock that makes up the Earth's lithosphere, moving and interacting with other plates.

Front

What is a transform boundary?

Back

A transform boundary is a type of plate boundary 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 and sinks into the mantle, often forming trenches and volcanic arcs.
