Surface Processes Pt. 1

Front

How does freezing water cause the weathering of rocks?  The freezing water—

Back

expands cracks and breaks rocks

Front

The process that breaks down rocks and other materials on Earth's surface is called

Back

weathering

Front

What is mechanical weathering?

Back

Process through which rocks are physically broken into smaller pieces.

Front

Which type of climate will have faster chemical weathering? Options: Hot and Wet, Cold and Dry, Hot and Cold, Cold and Wet

Back

Hot and Wet

Front

Which statement best explains why the process of water trapped in the cracks of a rock results in weathering? Options: frozen water acts as a solute, water expands when it freezes, the mass of water increases when it freezes, frozen water dissolves most types of rock

Back

water expands when it freezes

Front

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

Weeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:

Back

mechanical weathering

Front

All of the following are causes of physical weathering except... plant growth, wind, acid rain, running water

Back

acid rain

Front

Lichens (small green plants) growing on a large boulder release enzymes and other acids that slowly break the rock apart. This is an example of:

Back

chemical weathering

Front

Exposure to rain and oxygen causes the metal minerals in rocks to rust and fall apart. This is an example of: mechanical weathering, chemical weathering
