- The Earth’s rotation on its axis.
- The Earth’s revolution around the Sun in an elliptical manner.
- Latitudinal position of the place.
- Revolution of the Earth on-axis.
Which of the above-mentioned statement/statements is/are correct?
Answer: Option A. -> Only 2 and 4
Answer: (a)
Answer: (a)
Answer: Option A. -> Exosphere
Answer: (a)
Above Troposphere, temperature increases rapidly with height in the Stratosphere layer as it houses the ozone layer which absorbs ultraviolet (UV) rays from the sun.
Again, temperature increases rapidly with height in Thermosphere which comprises the Ionosphere (lower part) and Exosphere (upper part)).
The temperature in the Exosphere which is the uppermost layer of the atmosphere reaches up to more than 4500o Celsius.

Answer: (b)
Answer: (b)
Answer: Option D. -> Westerlies
Answer: (d)
The Roaring Forties is the name given to strong westerly winds found in the Southern Hemisphere, generally between the latitudes of 40 and 50 degrees.
The Westerlies play an important role in carrying the warm, equatorial waters and winds to the western coasts of continents, especially in the southern hemisphere because of its vast oceanic expanse.

Answer: Option A. -> Tropical easterlies
Answer: (a)
Answer: (a)
Answer: Option A. -> air current
Answer: (a)
An updraught or downdraught is the vertical movement of air as a weather-related phenomenon. Better known as air current, they can be caused by differences in temperature, pressure, or impurity concentration.
Temperature differences can cause air currents because warmer air is less dense than cooler air, causing the warmer air to appear 'lighter.' Rising air is associated with turbulence as it creates low pressure on the surface.
