SUB AERIAL PROCESSES

An example of chemical weathering is -

• Ice wedging

• Oxidation

• Animals burrowing

• Crashing waves

An example of physical weathering is -

• Plant roots and leaves releasing acids

• Carbonic acid dissolving limestone

• Large temperature changes

• Lichens growing on rocks

This rock may chemically weather easily because is has many spaces or holes in it that allow water to seep through it, meaning it is:

• permeable
• abrasive
• erosion
• unchangable

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
