Answer: 1- Option (D)
2- Option (A)
Explanation:
The green house gases plays a significant role in the earth's global temperature. In absence of green house gas, the earth would have been very much cold and life would would be difficult to exist. The average global temperature would have been about -15°C to 25°C. So the most favorable answer given here is that the<u> earth's temperature would have decrease by about 60°C</u>.
<u>Carbon dioxide (CO₂) is not the most abundant green house gas</u>. It is the second most abundant. The present composition of CO₂ in the atmosphere is about 0.04% by volume. A small increase in the CO₂ level, can lead to a global rise in the temperature. Hence, <u>the above statement is false.</u>

Sand is suspended in the water of seas and oceans by the action of waves and currents, and it is then deposited by the same wave action and storm surges at high tides or high water levels. Over time, the sand accumulates to create beaches, which are actually enormous sandbars.
<h3>Where will sand deposition cause the beach to spread for the first time?</h3>
around the area where the waves break. The sediments rub up against one another as a result of the moving water.
<h3>What is the primary reason for the incoming waves?</h3>
The most frequent waves are surface waves, which are brought on by wind moving over the air-water interface and causing a disturbance that gradually increases as the wind blows and the wave crest rises. The waves you see at the beach often are surface waves, which are continually present around the world.
