Earth's Processes

Which type of climate will have faster chemical weathering?

• Hot and Wet
• Cold and Dry
• Hot and Cold
• Cold and Wet

All of the following are causes of physical weathering EXCEPT...

• plant growth
• wind
• acid rain
• running water

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

• keeps the rocks in place
• makes the rocks last longer
• expands in the cracks and breaks rocks
• causes rocks to fall in landslides

What is sediment?

• the process of rocks being broken down and carried away
• bits of rock and sand caused by the weathering of rocks
• the top layer of the soil
• decaying plant or animal material 

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
• Plants don't weather rocks

What type of weathering is it when acid rain breaks down and changes the rock?

• chemical weathering 
• physical or mechanical weathering
• erosion

Picture A is a mountain in the Sierra Nevada. Picture B shows only the west ridge of the mountain range.  What is the most likely reason for the shape of picture B?

• It was hit by a volcano
• Chemical weathering
• mechanical weathering
• it was caused by an earthquake
