Which statement best describes the processes of weathering and erosion?

• Weathering and erosion are directly responsible for the breakdown of any type of rock into smaller particles and the carrying away of the loose sediments

• Weathering and erosion are directly responsible for depositing loose sediments on the bottom of the ocean, forming layers of sediment

• Weathering and erosion are directly responsible for the amount of water in a river that transports sediments to the sea

• Weathering and erosion are directly responsible for the transportation, deposition, and compaction of loose sediments on the seafloor

Erosion is one of the processes involved in the formation of sedimentary rock. Which of these best describes the process of erosion?

• Rocks are broken into smaller pieces that remain in the same location

• Pressure compacts layers of sediment and turns them into rock

• Pieces of rock or soil are carried from one place to another

• Sediment grains fall to the bottom of a lake to form sedimentary layers

The size and shape of a delta can change over time. The size and shape of this delta over time are NOT likely to be changed by -

• The number and height of tides along the shore

• The amount and size of sediments carried by the rivers and streams

• The amount of hunting and fishing in the area

• The number and size of waves from the ocean that reach the shore
