Semester 24 Review

Front

What geological forces might be responsible for mountain ranges?

Back

Converging tectonic plates are responsible for the formation of mountain ranges as they push against each other.

Front

What theory explains that continents were once joined together and drifted apart?

Back

Continental Drift explains that the continents were once a single landmass that broke apart and drifted to their current locations.

Front

What is a Divergent Boundary?

Back

A Divergent Boundary is where two tectonic plates move away from each other, allowing magma to rise and create new crust.

Front

What type of force causes objects to move?

Back

Unbalanced forces cause objects to move, as they result in a net force acting on the object.

Front

What explains that Earth's outer layer is broken into large, slowly moving pieces?

Back

Plate Tectonic Theory explains that Earth's outer layer is divided into tectonic plates that move over time.

Front

What is the result of converging tectonic plates?

Back

Converging tectonic plates can lead to the formation of mountains, earthquakes, and volcanic activity.

Front

What is the difference between erosion and deposition?

Back

Erosion is the process of wearing away land, while deposition is the process of laying down sediment in a new location.

Front

What is the significance of the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle, and is involved in tectonic activity.

Front

What happens at a Transform Boundary?

Back

At a Transform Boundary, two tectonic plates slide past each other, which can cause earthquakes.

Front

What is the role of magma in plate tectonics?

Back

Magma rises from the mantle at divergent boundaries to create new crust, contributing to the movement of tectonic plates.
