Understanding Water Weathering

While hiking, Jackson noticed the surface of a large rock crumbling into smaller pieces. What is this process called?

• Breaking down rock into smaller pieces

• The temperature or cloud conditions

• A method of predicting weather

• A type of plant

During a school project, James and Aria observed a stream flowing over a group of rocks. What is causing the weathering of these rocks?

• Wind blowing over rocks

• Water breaking down rocks into smaller pieces

• Chemical reactions in the atmosphere

• Animals walking over rocks

While on a school field trip to a national park, Scarlett noticed that the shapes of rocks near the river were different from those on the land. She learned that this is because both erosion and weathering break down rocks. However, what is a key difference between the two processes?

• Erosion involves movement, while weathering does not.

• Weathering can only happen with water, while erosion does not need water.

• Erosion happens only on the Earth's surface, while weathering happens below the surface.

• Weathering is a man-made process, while erosion is natural.

During a field trip, Rohan observed a river cutting through a canyon and wondered, what is the main factor that contributes to the erosion of rocks in this scenario?

• The color of the rocks

• The hardness of the rocks

• The presence of water

• The age of the rocks

During a field trip, Zoe observed a landscape and wondered which process is responsible for the formation of the soil beneath their feet. What did Sophia suggest as the answer?

• Compaction

• Weathering and erosion

• Solidification

While observing a garden, Luna noticed different soil layers and textures. What impact does weathering have on this soil formation?

• Chemical weathering adds helpful chemicals to the soil.

• Rocks are broken down into smaller pieces, and finally into sediment.

• Mechanical weathering adds ice to the soil, which turns into water.

• Volcanic eruptions contribute metamorphic rocks to the soil.
