Weathering, Erosion, and Deposition

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

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

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

• weathering
• erosion
• soil conservation
• decomposition

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.

Which type of climate will have faster chemical weathering?

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

During chemical weathering, what can happen to the type of rock that has undergone chemical weathering?

• a new rock is produced that is larger than the original rock
• a new rock is produced that is the same as the original rock
• a new rock is produced that is different from the original rock 
• no new rock is created - it is just smaller in size

A marble statue is left exposed to the weather.  Within a few years, the details on the statue have begun to weather away.  This weathering probably is caused by...

• oxygen in the air
• carbonic acid in rainwater
• lichens
• abrasion
