Why are oceans a major part of the water cycle?

• because they are large bodies of salt water that easily evaporate salt into the air

• because they are large bodies of salt water that fresh water can be evaporated from

• because the salt water condenses easily to become a gas in the air

• because the salt water runs off onto land to fill lakes and streams
