Exploring Changes to Earth's Surface Landforms

The video tutorial reviews the formation of various landforms such as deltas, canyons, sand dunes, glacier valleys, and mesas. It explains the processes of weathering, erosion, and deposition by wind, water, and ice. The tutorial also includes a question analysis section to reinforce understanding of these concepts.

What is the process called when rocks are broken down into smaller pieces?

• Erosion

• Weathering

• Deposition

• Sedimentation

Which landform is created by the slow movement of glaciers?

• Delta

• Sand dune

• V-shaped valley

• U-shaped valley

How are sand dunes primarily formed?

• By water erosion

• By wind deposition

• By volcanic activity

• By ice weathering

What natural process is responsible for the formation of canyons?

• Ice deposition

• Wind erosion

• Volcanic activity

• Water erosion

What happens to sediments when a river slows down at its mouth?

• They are compacted

• They are weathered

• They are deposited

• They are eroded

How do mesas differ from canyons in their formation?

• Mesas are formed by volcanic activity

• Mesas are formed by glaciers

• Mesas are formed by water flowing along the sides

• Mesas are formed by wind erosion

Why might a fence be built between sand dunes and a road?

• To stop sand from covering the road

• To prevent deltas from forming

• To keep water off the road

• To stop marine animals from nesting

Which feature is most likely formed by a glacier?

• Mountain ranges

• Y-shaped valley

• Deep ocean

• Lava flow

What type of sediment transport is the slowest?

• Ocean currents

• Glaciers

• Winds

• Rivers

How did the delta at the end of the Rio Grande form?

• By the river cutting through solid bedrock

• By sand and mud washed ashore by a tsunami

• By the river depositing large amounts of sediment

• By hurricanes pushing soil and debris
