Question

C. Tell me what.
1. What percentage of the Earth's surface is covered with water?
2. What constitutes the hydrosphere?
3. What is the main cause of waves on the surface of water?
4. What are ocean currents?
5. What negative effect does the mixing of warm and cold ocean currents produce?​

Answer 1

Explanation:

Ans 1=71%

Ans2- The hydrosphere is the liquid water component of the earth.It include the oceans,rivers and streams....The hydrosphere like the atmosphere is always in motio

Ans3- Waves are most commonly caused by wind.Wind driven waves or surface of ocean or a lake,the continual disturbance creates a wave crest ...The gravitational pull of the Sun and moon on the earth also causes waves.

Ans 4- ocean current is a continuous,directed movement of ocean water that flows in one of the earth's ocean.The current are generated from the forces acting upon the water like the earth's rotation ,the wind,the temperature and salinity differences and the gravitation of the moon.

Answer 2

Answer:

1. 71 percent

2. A hydrosphere is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. ... On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground—as groundwater, in wells and aquifer

3. Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. ... The gravitational pull of the sun and moon on the earth also causes waves.

4. 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.

5. Ocean water is on the move, affecting your climate, your local ecosystem, and the seafood that you eat. Ocean currents, abiotic features of the environment, are continuous and directed movements of ocean water. These currents are on the ocean’s surface and in its depths, flowing both locally and globally
