Slow Changes to Earth

Weathering and erosion are constantly changing Earth's surface. Which statement correctly describes the processes of weathering and erosion?

• Weathering is the movement of rocks by wind, water, and ice. Erosion is the breakdown of those rocks into sediment.

• Weathering is the process of depositing sediments. Erosion is the breakdown of rocks into sediment.

• Weathering is the breakdown of rocks by physical means. Erosion is the breakdown of rocks by chemical means.

• Weathering is the process of breaking down rocks into sediment. Erosion is the movement of sediments by wind, water, and ice.

Look at the image of sand dunes. Which correctly describes the process of sand dune formation? Choose all correct statements.

• A. A river carries sand from one location and deposits it on a growing hill downstream.

• B. Wind carries sand across a beach and deposits the sand on a growing hill away from the water.

Changes in Earth’s surface over time result in the formation of canyons and deltas. The sentences below describe how either deltas or canyons form. 1. Water or ice carries sediment away from its original location to the mouth of a river. 2. Wind, water, or ice carves a deep valley in rock. 3. Over time, the flow of water causes the river to sink lower between rock formations. Which answer matches the sentences to the landform it describes?

• Delta: 1; Canyons: 2 and 3

• Delta: 1 and 2; Canyons: 3

• Delta: 3; Canyons 1 and 2

• Delta: 2 and 3; Canyons: 1

Look at the image of a glacier. When a glacier moves, it has the ability to change the land. How do glaciers change the land and what evidence shows this change?

• By eroding and depositing materials; evidence includes U-shaped valleys and moraines.

• By causing earthquakes; evidence includes seismic activity.

• By changing weather patterns; evidence includes temperature fluctuations.

• By creating volcanic eruptions; evidence includes lava flows.
