Which two details are most important to include in a summary of the excerpt?

excerpt from Robinson Crusoe

by Daniel Defoe

When I waked it was broad day, the weather clear, and the storm abated, so that the sea did not rage and swell as before. But that which

surprised me most was, that the ship was lifted off in the night from the sand where she lay by the swelling of the tide, and was driven up

almost as far as the rock which I at first mentioned, where I had been so bruised by the wave dashing me against it. This being within

about a mile from the shore where I was, and the ship seeming to stand upright still, I wished myself on board, that at least I might save

some necessary things for my use.

When I came down from my apartment in the tree, I looked about me again, and the first thing I found was the boat, which lay, as the wind

and the sea had tossed her up, upon the land, about two miles on my right hand. I walked as far as I could upon the shore to have got to

her, but found a neck or inlet of water between me and the boat which was about half a mile broad; so I came back for the present, being

more intent upon getting at the ship, where I hoped to find something for my present subsistence.

What is the difference between an exchange pool and a reservoir? What role do these areas play in the water cycle?
goldfiish [28.3K]

Answer:

EXCHANGE POOL is a part of the cycle that holds water for a short period of time. 

RESERVOIR POOL is a part of the cycle that holds water for a long period of time. 

So, the main difference is the period of time each one holds water during the water cycle. 

Explanation:

Water is recycled during the water cycle. Chemical elements and water that are important for an ecosystem and the animals living in it are CONSTANTLY being recycled.  For instance, chemicals might travel from organisms to the atmosphere or oceans and come back to the organisms again. But, it certainly happens that water is held for many years in different parts of the cycle. For example, the atmosphere plays the role of an exchange pool because it holds the water in the shape of vapor for just a few days. The ocean is a reservoir for water since it may hold water for thousands of years. The water cycle happens on, above and below earth surface, so the water cycle is a global cycle.
