Question

1. Answer the following questions.
(i) What is precipitation?
(ii) What is water cycle?
(iii) What are the factors affecting the height of the waves?
(iv) Which factors affect the movement of ocean water?
(v) What are tides and how are they caused?
(vi) What are ocean currents?​

Answer 1

Answer:

1)The sun's heat vaporises water into vapour. This vapour cools down and condenses to become clouds. This may then fall on the surface of Earth in the form of rain, snow or sleet. This phenomenon of water falling back onto the surface of the earth in the form of rain, snow or sleet is called precipitation

2)the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

3)Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction.

4)characteristics like temperature, salinity, density and the external forces like of the sun, moon and the winds influence the movement of ocean water. The horizontal and vertical motions are common in ocean water bodies. The horizontal motion refers to the ocean currents and waves. The vertical motion refers to tides.

5)Tides are caused by gravitational pull of the moon and the sun. The rise and fall of the tides play an important role in the natural world and can have a marked effect on maritime-related

6)An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.

Answer 2

Answer:

1. Precipitation:-

Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth.

2.Water cycle:-

The water cycle describes how water is exchanged (cycled) through Earth's land, ocean, and atmosphere.

3.Factors affecting the height of the waves:-

Winds, earthquakes, volcanic eruption or under water landslides are the factors affecting the height of the waves. The stronger the wind blows, the bigger the wave becomes.

4. Factors affecting the movement of ocean water:-

Temperature, winds, gravitational pull of the sun, the earth and the moon, warm and cold currents are the factors that affect the movement of ocean water.

5.tides and there caused :-

Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun, and the rotation of the Earth.

The strong gravitational pull exerted by the sun and the moon on the earth's surface causes the tides.

6.Ocean Currents :-

An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.
