Lori is learning about two parts of the rock cycle: weathering and erosion. She needs to explain how weathering and erosion are different. Which of the following correctly describes the difference between weathering and erosion?

• Weathering is the movement of rocks by wind; erosion is the movement of rocks by water.

• Weathering is the formation of rocks from lava; erosion is the weathered materials from an area.

• Weathering is the breaking down of rocks; erosion is the movement of weathered materials

• Weathering is when rocks change from one type of rock to another; erosion is when rocks are broken down

Many places, like the Grand Canyon, are the result of a combination of processes that continue to shape Earth, like the water cycle and the rock cycle. How does the water cycle influence the rock cycle in an area like the Grand Canyon?

• Large amounts of flowing water increases the rate of weathering and erosion.

• Too much rain soaking into the ground slows the rate of new rock formation.

• Sudden evaporation of water removes moisture from rock layers in the canyon walls.

• Decreased rainfall makes the rocks hard and brittle, so that they crumble into pebbles

Compared to Earth's crust, Earth's core is believed to be?

• Less dense, cooler, and composed of more iron

Based on the diagram which process explains why less dense, hot magma rises to the surface to displace denser, cooler, magma?

• conduction

• diffusion

• radiation

• convection

The Andes mountains are the longest of all the world's continental mountain ridges. Which of the following correctly explains how this mountain range was formed?

• tectonic plates collided, and earth's crust was pushed upward

• tectonic plates separated, and exposed magma boiled upwards

• tectonic plates slipped past each other and pushed material upward

• tectonic plates collided and thousands of volcanoes were formed
