Plate Tectonics STAAR Review

Front

What is Wegener's theory of continental drift?

Back

Wegener's theory states that the continents were once joined together in a single landmass and have slowly moved apart over time.

Front

What does it indicate when lines are closest together on a topographic map?

Back

It indicates that the terrain is steep.

Front

What is a contour line?

Back

A contour line is a line drawn on a map that connects all points with the same elevation.

Front

In which direction is a stream flowing if it is indicated to flow eastward?

Back

The stream is flowing towards the east.

Front

What type of boundary is formed when two tectonic plates slide past each other?

Back

This is known as a transform boundary.

Front

What is a convergent boundary?

Back

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

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, leading to the formation of new crust.

Front

What is the purpose of a topographic map?

Back

A topographic map shows the elevation and terrain features of an area.

Front

What happens at transform boundaries?

Back

At transform boundaries, tectonic plates slide past each other, which can cause earthquakes.

Front

What is the significance of contour intervals on a map?

Back

Contour intervals indicate the difference in elevation between adjacent contour lines.
