Which statements are true?
hurricanes can be caused by physical processes in the hydrosphere.
most of the earth's freshwater can be found in the air and streams.
most plants and animals need freshwater to survive.
ocean currents move warm water from the equator toward the poles.
the water cycle is powered by the sun.

The correct answer is - 1), 3), 4) and 5) are correct statements.

Explanation:

Hurricanes are the tropical storm caused in tropical or sub tropical water bodies. Hurricanes are tropic cyclone caused where warm air rises from ocean water and replaced by the cooler are and then again with warm air and cooler in rapid manner.

Most plants and animals need fresh water for their survival because body comprises water to perform several reaction and prevent from dehydration.

Ocean currents move warm water to the poles from the equator due to regulation of the global water temperature. Thus is maintained by the m,mechanism of the convection current that carries the warm water from the equator to the poles and at the poles, these warm warm because of the lowering temperature, cools an sinks.

The water cycle is the process in which water circulates within the spheres and begins with evaporation by sun.

Thus, the correct answer is - 1), 3), 4) and 5) are correct statements.
