Why do batteries have a positive and negative side?
The battery has 2 sides just because.
The battery needs to form a complete circuit.
One side is for the switch, the other is for a light bulb.
One side is to turn it on, the other is to produce more power.
When the lamp is turned on and the bulb is lit, the circuit demonstrates which of the following?

Which statement best describes the processes of weathering and erosion?
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 breakdown of any type of rock into smaller particles and the carrying away of the loose sediments.
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.
