Weathering

The process of breaking up Earth's surface into soil and sediment over a long period of time  is called...

• sediment
• erosion
• weathering
• deposition 

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

• chemical weathering 

• mechanical weathering

• erosion

• deposition

• mechanical weathering

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

What type of weathering is caused by animal actions?

• Chemical Weathering 

• Erosion 

• Mechanical Weathering 

• Animals 

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

• abrasion

• hydrolysis

• acid rain

All rocks break down into smaller material.

• True

• False

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering

• chemical weathering

• differential weathering

• deposition

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

• mechanical weathering

• chemical weathering

• differential weathering

• deposition

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
