The process of breaking up rocks on Earth's surface is called...

• sediment

• erosion

• weathering

• deposition

What can you infer about ice?

• It usually causes chemical weathering.

• It expands as it freezes.

• It barely causes weathering at all.

• It does not exert pressure on rocks.

What is mechanical weathering?

• Process through which rocks are physically broken into smaller pieces

• Rocks are broken down through chemical changes.

• Rocks are worn away from acid in plant roots.

• Rocks broken down by machinery

How do plants weather rocks?

• during photosynthesis
• when roots grow into cracks of rocks and expand the rock
• when the plant moves water from the roots to the leaves
