BJU7 Science Chapter 7: Mountains and Hills

Front

What is a graben?

Back

A graben is a divergent landform that forms when a block of the Earth's crust sinks between two faults.

Front

What are mountain landforms made of anticlines and synclines called?

Back

Fold mountains.

Front

What does elevation refer to?

Back

Elevation is the height of a mountain's peak above mean sea level.

Front

What primarily caused the erosion processes that formed buttes and mesas?

Back

These were mostly formed as the waters from the Flood receded.

Front

In an eroded syncline, where do the older exposed rocks lie?

Back

The older, exposed rocks lie to both sides of the fold.

Front

What is a fold mountain?

Back

A fold mountain is a type of mountain formed by the folding of the Earth's crust due to tectonic forces.

Front

What is the difference between a graben and a horst?

Back

A graben is a block of the Earth's crust that has sunk, while a horst is a block that has risen.

Front

What is a fault-block mountain?

Back

Fault-block mountains are formed when large blocks of the Earth's crust are lifted or tilted.

Front

What is a syncline?

Back

A syncline is a downward fold in rock layers, where the youngest rocks are at the center.

Front

What is an anticline?

Back

An anticline is an upward fold in rock layers, where the oldest rocks are at the center.
