Chemical or Mechanical Weathering

An acid that forms from the result of water mixing with carbon dioxide gas in the air or soil.

Halite ( a mineral in rocks) reacting in water

• Mechanical Weathering

• Chemical Weathering

• Both Mechanical and Chemical Weathering

Substances from decaying plants reacting with minerals in rocks

• Mechanical Weathering

• Chemical Weathering

• Both Mechanical and Chemical Weathering

Repeated freezing and thawing of water that cracks rock

• Mechanical Weathering

• Both Mechanical and Chemical Weathering

Ice wedging will

• wear down rocks as they bounce together 

• break up rocks when the water in cracks freezes and thaws

• peel away loosend material from the surface of rocks.

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

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

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
