Multiple Choice

How does freezing water cause the weathering of rocks?

• It keeps the rocks in place.

• It expands cracks and breaks rocks.

• It makes the rocks last longer

• It causes rocks to fall in landslides

Multiple Choice

What is the process called when water freezes in cracks, expands, and pushes the rock apart?

Typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases.

Multiple Choice

Describe the role of tectonic plate boundaries in the formation of the Ring of Fire.

• They create stable regions with no volcanic activity.

• They are areas where plates move apart, causing earthquakes.

• They are zones where plates collide or slide past each other, leading to volcanic activity.

• They are regions where plates are stationary, preventing volcanic eruptions.
