Answer:

Explanation:

  • For about 14.6% of the Earth's Fresh water supply comes from ground water.
  • The share of the liquid fresh water of the Earth that accounts for ground water is about 94.05%.
  • The two geological roles of ground water are given below:
  1. It acts as an erosional agent.
  2. It acts as a stream flow equalizer, i.e., it is a sort of storage form in order to provide sustainability to the streams during dry periods.
  • For about 23% of U.S fresh water is provided by ground water.
  • Most of the ground water is utilized for irrigation purposes.

2. How much Potential Energy is gained when a 1250 N mass is raised a vertical distance of<br>35 m?​
vichka [17]

Potential Energy

The potential energy gained is 43750 J

Explanation:

Potential energy is the energy by virtue of an object's position relative to the ground ie, the height of the other object.

For example, an object has more potential energy when it is on top of a two-story building than it does resting on the ground. That's because the object's relative position to the Earth gives it more energy.

Potential Energy is defined as

Potential energy = Mass * height

Given Mass M = 1250 N

Given height h = 35 m

So the potential energy = 1250 * 35 = 43750 J

Thus the potential energy is 43750 J

The hawaiian islands are located where the pacific plate is:
damaskus [11]
The Hawaiian Islands are formed on a region of intra plate volcanic activity on the Pacific plate. This region is known as a hot spot. Scientists are not exactly sure what causes this but they do know that a plume of magma rises through the mantle and forces it's way through the crust to form submarine volcanoes and over time volcanic islands.
The magma that rises here originates from the mantle and not crustal melt and so forms basic or basaltic lava.

The latitude in New York City is about 40 degrees north. Do the Sun’s rays ever shine directly overhead in New York City? Explai
Alona [7]
For continental U.S. the answer is never. Since the earth's rotation axis is tilted 23.5 degrees with respect to its orbital motion around the su, one would have to be less than 23.5 degrees above or below the equator to have the sun pass direclty overhead
