Earth Structures: Weathering and Erosion

What is weathering?

• Process that breaks down rock into smaller pieces called sediment

• Process by which wind, water, ice, or gravity transports soil and sediment from one location to another

• Wind, water, ice, gravity

• Ice, wind, water, gravity, plant root, and temperature change

The tops of some mountains are sharp and pointed, while the tops of others are smooth and rounded. This difference was most likely caused by

• rivers flooding along a coastal plain

• erosion and weathering

• earthquakes and waves

• rocks melted underground by lava.

A scientist wanting to document a change in a river's flow pattern should observe a river a period of

• days

• weeks

• months

• years

A plateau is most likely formed by

• runoff from a river

• weathering by waves

• erosion of rock debris

• a buildup of cooled lava

Changes to Earth's surface can happen slowly or quickly. Which of these changes happens the most quickly?

• a mountain eroding to a hill

• a river making a delta

• a glacier making a canyon

• a storm moving a sandbar

Which is most similar to the way a glacier makes a valley

• a bulldozer pushes a pile of dirt

• a shoe makes a footprint in soil

• a tree root splits a rock in half

• a drill makes a hole in a board
