BJU7 Science Chapter 7: Mountains and Hills

Front

What are fold mountains?

Back

Mountains formed by the folding of the Earth's crust, typically consisting of anticlines and synclines.

Front

What is a basin in geological terms?

Back

A subsidence landform where the land has sunk, often collecting water or sediment.

Front

What does it indicate if folded sedimentary rock strata are smoothly shaped?

Back

It indicates that the strata were still soft when they were quickly folded.

Front

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

Back

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

Front

What is the longest and most extensive mountain system on Earth?

Back

The Mid-Atlantic Range.

Front

What are anticlines and synclines?

Back

Anticlines are upward folds in rock layers, while synclines are downward folds.

Front

What is the difference between a fault-block mountain and a fold mountain?

Back

Fault-block mountains are formed by tectonic forces that fracture the Earth's crust, while fold mountains are formed by the bending of rock layers.

Front

What is subsidence?

Back

The gradual sinking of the Earth's surface, often leading to the formation of basins.

Front

What type of landform is created by the accumulation of sediment?

Back

Depositional landform.

Front

What is the significance of the Mid-Atlantic Range?

Back

It is the longest mountain range in the world, running down the center of the Atlantic Ocean.
