Conserving water can save money while protecting the environment. True or False
blagie [28]

Answer: The given statement is true.

Explanation:

Water is a natural resource present in the nature and it is very precious as life without it is impossible.

So, when we unnecessarily use water then it means we are wasting a natural resource that cannot be reproduced again by human beings.

Therefore, more we are able to conserve water more we can protect other human life's and environment also.

If there is shortage of water then its prices will go high and hence we need to pay more for it.

Thus, we can conclude that the statement conserving water can save money while protecting the environment, is true.

Daniel [21]

c. The energy source of tsunami waves is much greater

Explanation:

The major difference between a tsunami waves and ripple waves is that the energy source of tsunami waves is much greater compared to ripple waves.

Tsunami waves carry more energy compared to just a disturbance resulting from a ripple caused by dropping of a stone.

  • A tsunami is a large water wave caused by the displacement of water usually by an earthquake.
  • An earthquake is a releases elastic waves suddenly within the earth crust.
  • Water bodies at the epicenter are disturbed sending huge volume of energetic water loads to the land.
  • A ripple is just a product of a stone dropped inside the water.
