Types of Weathering

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• ice wedging
• acid rain
• permeability
• abrasion

These rocks were made smooth by wind blowing smaller rock particles across their surface.  This is an example of:

• ice wedging
• chemical weathering
• acid rain
• abrasion

Acid rain wearing away the face of a marble gravestone or statue is an example of?

• mechanical weathering
• chemical weathering

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

• carbonation
• oxidation
• Hydrolysis
• Acid Precipitation

Rust that forms on rocks or metal because of extended exposure to oxygen is what example of chemical weathering?

• carbon dioxide (carbonic acid)
• acid rain
• oxidation
• living organisms

What are the two factors that affect the rate at which weathering occurs?

• climate and mass of rock
• climate and size of rock
• type of rock and size of rock
• type of rock and climate

Which type of climate will have faster chemical weathering?

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

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.

The formation of stalactites and stalagmites in a cave as water mixed with carbon dioxide creates carbonic acid, which dissolves away the limestone, is an example of:

• acid  precipitation
• carbonation
• hydrolysis
• oxidation
