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
