Section C
1) Ocean currents are driven by wind, water density differences, and tides. Oceanic currents describe the movement of water from one location to another. By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. Ocean currents are also critically important to sea life. They carry nutrients and food to organisms that live permanently attached in one place and carry reproductive cells and ocean life to new places.
2) Tides are the rise and fall of seawater due to the gravitational forces of the sun and the moon. Tides are mainly caused by the centrifugal and centripetal forces of the earth and the moon.
3) Moisture is the presence of a liquid, especially water, often in trace amounts.
Rainfall has been classified into three types based on the origin –
1) Convectional rainfall
2) Orographic rainfall
3) Cyclonic rainfall
4) Troposphere:
1. The troposphere is the lowest layer of Earth's atmosphere,
2. It is the densest layer of the atmosphere and contains approximately 75 per cent of the mass of the atmosphere and almost all the water vapour and aerosol.
Stratosphere:
1. The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward.
2. The stratosphere is stratified in temperature, with warmer layers higher and cooler layers closer to the Earth; this increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet radiation by the ozone layer.
