Question

E.Answer the following questions.
1. How are tides useful to us?
2.How are oceans beneficial to us in improving the quality of life?
3. Explain the water cycle with the help of a diagram.
4. Explain three effects of ocean currents.
5. Suggest four ways to help people affected by devastation due to Tsunami.​

Answer 1

1.Tides help us in the following ways: High tides help in navigation. This helps the ships to arrive at the harbour more easily. ... Tides are also helpful in generating to.

2.The air we breathe: The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns

3.The Sun, which drives the water cycle, heats water in oceans and seas. Water evaporates as water vapour into the air. When the water vapour rises, it starts cooling. The water vapour condenses causing the formation of droplets of water.

4.The following are the three effects of ocean currents:

It keeps the temperature high and makes the area more heated than the surrounding areas. The warm ocean currents led to rainfall. It shares minerals & pollution attached to it becomes profoundly adulterated & later negligible.

5.Suggest four ways to help people affected by devastation due to tsunami

Answer 2

Answer:

1. Tides help us in the following ways:
2. • High tides help in navigation. This helps the ships to arrive at the harbour more easily.
3. • The high tides also help in fish
4. • Tides are also helpful in generating electricity.
5. 3 quality of oceans are
7. 1)high tide enable the big ship to enter in a harbour or sail out of harbour
9. 2) high tide enable to harnessed or generate electricity in coastal area
11. 3) it provide ideal condition to plankton which is food for marine life
12. ANSWER
13. Water from bodies raise up in the form of water vaporous farmed by evaporation. clouds are formed due to condensation of water vaporous and then water returns back to the water bodies as rain. this circulation of water is called water cycle. (attachment is given)
14. Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
15. 1) Search for people stuck under tight spaces!
16. 2) make a list of people lost and keep advertising till every family is united and supply them with food and water
17. 3) Move them to safe place and make them feel everything is going to be fine
18. 4) Bring first aid and medical help as soon as possible
19. 5) Remember! Moral support is the key to build their strength. so keep assuring them that they're safe
20. 6) conduct fund raising events to financially aid them
