Why is water classified as a renewable resource?

a). water is constantly being recycled through earth’s system.

b.) groundwater that is rarely used makes up 80% of the earth’s water.

c). the ocean is not considered to be resource and it’s water is not counted as a resource.

d). water is renewed through the removal of salt from seawater and factories all over the world.

(never mind i figured it out)
the answer was a

Option (A)

Explanation:

The resources that can be regenerated again over a specific period of time are known as renewable resources. For example, Wind, Water, and Sunlight.

Water is one of the most necessary and valuable renewable resources. It is considered to be renewable because it can be obtained again and again by undergoing certain processes that form a cycle which is commonly known as the water cycle.

In the water cycle, the water moves from the surface to the atmosphere in the form of vapor by undergoing the process of evaporation and transpiration and comes back to the surface in the form of rainfall, by undergoing the process of condensation.

This is how water changes its phase from one type to another, recycling within the system, thereby regenerating it. So, water is usually classified as a renewable resource.

Thus, the correct answer is option (A).

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
