6E6.1 Weathering (chem & phy), Erosion, and Deposition

What are the three main processes involved in the formation of sedimentary rocks?

• Melting, cooling, and crystallization

• Weathering, erosion, and deposition

• Compaction, cementation, and lithification

• Metamorphism, melting, and solidification

What is the result of mechanical weathering?

• Sediments are laid down in horizontal layers

• Sediments are moved to a new location

• Large rocks dissolve into smaller pieces

• Large rocks break into smaller pieces called sediments

Which type of weathering involves the chemical dissolution of rocks?

• Physical weathering

• Biological weathering

• Mechanical weathering

• Chemical weathering

What is erosion?

• The process of breaking down rocks into smaller pieces

• The movement of sediments to a new location

• The laying down of sediments in new locations

• The formation of fossils in sedimentary rocks

Which natural force is NOT involved in erosion?

• Water

• Wind

• Gravity

• Heat

What happens during deposition?

• Sediments are broken down into smaller pieces

• Sediments are dissolved chemically

• Sediments are moved to a new location

• Sediments are dropped in a new location

How are sediments usually laid down during deposition?

• Vertically

• Horizontally

• Randomly

• Diagonally

What can sedimentary rocks tell us about past environments?

• The age of the Earth

• The types of plants that existed

• The conditions under which the sediments were deposited

• The types of animals that lived
