Question

Identify the statement that is true about a reservoir. Choose one:

(A) A reservoir of sedimentary rock at the bottom of the ocean is called eclogite.
(B) It must have a biological component in order to transfer materials to another reservoir.
(C) A reservoir of metamorphic rock needs the addition of heat and pressure in order to change into a reservoir of sedimentary rock.
(D) It is a component in the Earth System that holds material for a period of time.

Answer 1

Option (D)

Step-by-step explanation:

A reservoir is usually defined as a place where a large amount of water or other economic minerals are trapped or stored. They are formed by both artificially as well as naturally. These reservoirs form a part of the earth system.

Generally, a reservoir is a part of the earth system which stores the materials for a longer period of time.

For example, a water reservoir that stores water in it and is used in the production of electricity.

Hence, the correct answer is option (D).

Answer 2

option D

Step-by-step explanation:

The correct answer is option D

A reservoir is used to hold the material over a period of time.

A reservoir is used to store water so that it can be used for different purposes such as irrigation, flood control, and electricity production.

A reservoir can also be used to maintain the flow of water even when the flow in the river is less.

so, we can say that a reservoir is used to hold material.
