7E6.2 Weathering Erosion 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?

• Rocks melt and form magma

• Large rocks dissolve into smaller pieces

• Large rocks break into smaller pieces called sediments

• Rocks change their chemical composition

Which type of weathering involves the chemical breakdown of rocks?

• Biological weathering

• Chemical weathering

• Physical weathering

• Mechanical weathering

What is erosion?

• The movement of sediments to a new location

• The laying down of sediments in a new location

• The melting of rocks into magma

• The process of breaking down rocks into smaller pieces

What happens during deposition?

• Sediments are moved to a new location

• Sediments are dropped in a new location

• Sediments are broken down into smaller pieces

• Sediments are melted into magma

How are sediments usually laid down during deposition?

• Vertically

• Horizontally

• Diagonally

• Randomly

What can sedimentary rocks tell us about past environments?

• The events that caused the sediments to deposit

• The age of the Earth

• The climate conditions at the time

• The type of organisms that lived there

What is the role of the San Andreas Fault in the formation of the Marin Headlands chert?

• It dissolved the rocks chemically

• It caused the rocks to melt

• It moved the rocks to a new location

• It crumpled the originally horizontal layers
