<u>Answer:</u>
Carbon is found in hydrosphere in the form of dissolved carbon in ocean and sea water during the gas exchange process.
<u>Explanation:</u>
- Carbon cycle is the process of transformation of carbon in different forms. From atmosphere, the carbon gets into hydrosphere during the gas exchange processes.
- During this gas exchange process, the carbon is dissolved in the ocean water which is later utilized by marine plants to conduct photosynthesis.
- There is a continuous transformation of carbon from lands, plants to atmosphere and from atmosphere to hydrosphere.
Earth's surface wind generally blow from regions of higher AIR PRESSURE TOWARDS REGION OF LOWER AIR PRESSURE.
The direction in which the wind blow on the earth surface is a product of many factors, the most important of these factors are: pressure, friction and Coriolis effects. On the earth surface, the wind normally blow from high to low pressure. A high pressure system followed by a low pressure system allows the wind to flow in clockwise direction outward toward a low pressure system. This ensures the continuous flow of the wind.
