Plate Tectonics

Front

What is the lithosphere made up of?

Back

The lithosphere is made up of the crust and upper mantle.

Front

What type of mountain range are the Black Hills of South Dakota an example of?

Back

The Black Hills of South Dakota are a good example of a dome mountain range.

Front

Who argued forcefully for the theory of continental drift?

Back

Alfred Wegener argued forcefully for continental drift.

Front

Which type of fault has little to no vertical movement?

Back

The strike slip fault has little to no vertical movement.

Front

Where is older, cooler, more dense oceanic crust subducted?

Back

Older, cooler, more dense oceanic crust is subducted into the mantle at subduction zones along convergent plate boundaries.

Front

What is the definition of plate tectonics?

Back

Plate tectonics is the scientific theory that describes the large-scale movements of Earth's lithosphere, which is divided into tectonic plates.

Front

What are the three main types of plate boundaries?

Back

The three main types of plate boundaries are divergent, convergent, and transform boundaries.

Front

What occurs at divergent plate boundaries?

Back

At divergent plate boundaries, tectonic plates move away from each other, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate moves under another and is forced into the mantle, often leading to volcanic activity.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is thinner, denser, and younger than continental crust, which is thicker, less dense, and older.
