Janice and James are studying a rock formation near their school. They are specifically looking for the processes of physical weathering. When examining the rock and the environment for physical weathering, what types of things should they look for?

• the formation of clay minerals, leaching, and animal activity in the area

• the presence of lichens, various types of crystals, and fossils

• the formation of salt crystals, fractures in the rock, and seasonal temperature fluctuations

• the presence of different minerals on the surface, various colors, and plant roots

Look at the image below. Which of the following has most likely happened?

• The plant has dissolved the rock.

• The plant has eroded the rock.

• The plant has eaten away the rock.

• The plant has weathered the rock.

Ryder has been visiting his favorite park for ten years. Recently, he noticed that the large boulder in the center of the park has gotten smaller and smoother in some places. Why has the boulder changed?

• The heat of the Sun evaporated out the water, causing the boulder to shrink.

• Wind and water have weathered the boulder, wearing away at its surface.

• The weight of the boulder has caused its rock particles to compress.

• The rock particles in the boulder have cemented into thinner layers.

• high rainfall

• thick soils

• cold temperature

Laura wants to develop a model that shows how natural processes can suddenly change the Earth's surface. Which of the following could she show in her model?

A student wants to create pictures that show what could happen when ice forms inside a small crack in a rock. Which three things should the student show happening to the rock in his pictures?

• Broken pieces of rock moving by erosion.

• The ice hardening in the crack, making new rock.

• Ice making the crack smaller.

• The rock breaking apart along the crack.

• The crack continuing to widen.
