Regents Review #5 - Surface Processes

Front

What is a U-shaped valley?

Back

A U-shaped valley is a valley formed by the erosion of a glacier, characterized by its U-shaped cross-section and steep sides.

Front

What are glacial moraines?

Back

Glacial moraines are accumulations of debris (rocks and sediment) that have been transported and deposited by a glacier, typically unsorted and not layered.

Front

How do glaciers alter landscapes?

Back

Glaciers alter landscapes through processes of erosion and deposition, creating features such as U-shaped valleys, fjords, and moraines.

Front

What is the difference between a U-shaped valley and a V-shaped valley?

Back

A U-shaped valley is formed by glacial erosion, while a V-shaped valley is typically formed by river erosion.

Front

What is a stream drainage pattern?

Back

A stream drainage pattern is the arrangement of a network of streams and rivers in a particular area, influenced by the underlying geology and topography.

Front

What is the significance of sediment sorting in glacial deposits?

Back

Sediment sorting refers to the distribution of particle sizes in sediment; glacial deposits are typically unsorted due to the way glaciers transport materials.

Front

What is the Allegheny Plateau?

Back

The Allegheny Plateau is a region in New York State characterized by its elevated terrain and is known for the longest portion of the Genesee River.

Front

What happens to sediment when a stream enters the ocean?

Back

When a stream enters the ocean, it typically slows down, causing sediment to settle and form deltas.

Front

What are the characteristics of sediments in glacial environments?

Back

Sediments in glacial environments are usually unsorted and can include a mix of various sizes, from fine silt to large boulders.

Front

What is the role of glaciers in shaping landforms?

Back

Glaciers shape landforms through processes of erosion, transporting materials, and depositing them in new locations.
