Weathering and Erosion

What causes weathering?

• natural processes only

• chemical processes only

• physical processes only

• weather-related processes only

• physical and chemical processes

What can result when acids in groundwater weather limestone rocks underground?

• Caves can form as the acids dissolve rocks over time.

• Crystals can grow as the water deposits minerals on the rocks.

• Kettle lakes may build up from the excess water.

• Sand formations can build up as the water causes abrasion of the rocks.

• Molten rock can form as the chemical reactions with the acids heat the rocks.

Which claim explains how chemical weathering differs from physical weathering?

• Human activity causes chemical weathering but does not cause physical weathering.

• Chemical weathering does not break rocks down into smaller parts, but physical weathering does.

• Chemical weathering is acid precipitation and pressure, and physical weathering is wind and temperature changes.

• Chemical weathering happens when the bonds that hold minerals together break; physical weathering happens when physical actions wear away and crack the rocks.

Storms can cause major changes to barrier islands by removing sand from the island. Based on this evidence, which of the following would you claim would remove the most sand from a barrier island during a storm?

• waves depositing debris on the island

• large waves crashing on the island

• strong winds blowing across the island

• currents moving sand along the island

After heavy rainfall, a stream causes more erosion than usual. What reasoning most likely explains this?

• The stream contains more water and

  moves faster.

• The stream contains more water and

  moves slower.

• The stream contains less water and

  moves slower.

• The stream contains less water and

  moves faster.

• temperature

• wind

• gravity

Glaciers form in cold areas with lots of snow. The snow must turn into ice to form a glacier. What reasoning explains how this happens?

• The snow melts as it falls and then freezes once it hits the cold ground.

• The temperature on the ground is cold enough to turn the snow into ice.

• The snow builds up, and its weight compresses the snow below into ice.

• The cold wind blows across the top of the snow, turning it into ice.

The tallest sand dunes in North America are found in Great Sand Dunes National Park and Preserve in Colorado. These dunes were formed from the sand at the bottom of a dry lake bed. Which of the following agents is most likely responsible for the formation of the sand dunes?

• water

• gravity

• ice

• wind
