How does the rate of weathering and erosion change when strong winds are present compared to when winds are calm?

• The rate is slower in strong winds.
• The rate is faster in strong winds.
• The rate remains the same regardless of wind conditions.
• The rate is affected by the steepness of the terrain, not the wind.

Imagine a big boulder sitting on a riverbed. Over many years, the surface of the boulder starts to crack and break into smaller pieces due to the freezing and thawing of water inside its cracks. This situation is an example of ____________ caused by ____________.

• weathering; wind
• erosion; wind
• weathering; water
• erosion; water

Picture a sandy beach. Over time, strong ocean waves gradually carry away small grains of sand from the beach, making it slightly smaller year after year. This situation is an example of ____________ caused by ____________.

• weathering; wind
• erosion; wind
• weathering; water
• erosion; water

Which of the following situations is an example of how vegetation can affect weathering and erosion?

• Strong wind can blow tiny grains of sand against rocks. Over time, the constant rubbing of sand against the rocks can wear them down, making the rocks smoother and smaller.
• When it rains in the desert, water can flow quickly through dry riverbeds. As it rushes, it can pick up loose sand and dirt, carving out deeper channels over time, creating canyons.
• The roots of plants and trees can grow into cracks in rocks. As these roots grow, they push against the rocks and make the cracks wider, causing the rocks to break apart over time.
• All of the above
• None of the above
