• Tornados

• water

• animals

WHy is water a major factor in chemical weathering?

• water trickles over thousands of years to create caves

• water can dissolve or break down certain minerals

• water can move eroded materials

• water causes sinkholes

Where does most weathering take place?

• inside the Earth

• inside the LAC school

• on the Earth's surface

• on the playground

• hills

• mountanis

• plateaus

• caves

What is a glacier?
