What is weathering?

• The process of rocks melting

• The breakdown of rocks into smaller pieces

• The formation of new rocks

• The movement of rocks

Which of the following is an example of chemical weathering?

• Frost wedging

• Oxidation

• Abrasion

What is erosion?

• The process of rocks forming

• The movement of sediment from one place to another

• The melting of rocks

• The cooling of magma

Which characteristic is typical of sedimentary rocks?

• They have a glassy texture

• They contain fossils

• They are formed from cooled magma

• They have a foliated structure

What is the primary agent of erosion?

• Wind
