1. The energy received by the earth from the sun is known as
Insolation.
Perhelion.
Conduction.
Advection.
Answer: (a) Insolation.
Solution: The earth's surface receives most of its energy in short waves and insolation is the energy received by the earth. It is also known as incoming solar radiation.
2. Which of the following is not the factor responsible for controlling temperature distribution?
Latitude.
Altitude of the place.
Pressure.
Distance from the sea.
Answer: (c) Pressure.
Solution: The factors contributing to temperature distribution are (1) The altitude of the place, (2) The latitude of the place, (3) The Distance from the sea, (4) The presence of warm and cold ocean currents, and (5) Local aspects.
3. The atmosphere is mainly heated by
Long wave terrestrial radiation.
Short wave solar radiation.
Reflected terrestrial radiation.
Scattered solar radiation.
Answer: (a) Long wave terrestrial radiation.
Solution: The earth after being heated becomes a radiating body itself and it radiates energy to the atmosphere in a long waveform. This energy heats up the atmosphere from below, and this process is known to be terrestrial radiation.
4. In the northern hemisphere, the Coriolis force deflects the winds towards
South direction.
North-east direction.
South-west direction.
South direction.
Answer: (d) South direction.
Solution: The rotation of the earth about its axis affects the direction of the wind, and the force acting on it is called the Coriolis force. It deflects the wind to the right direction in the northern hemisphere, and to the left in the southern hemisphere.
5. The cool air of the high plateaus and ice fields draining into the valley is known as
Local wind.
Land breeze.
Katabatic wind.
Mountain breeze.
Answer: (c) Katabatic wind.
Solution: The cool air of the high plateaus and ice fields draining into the valley is known as a katabatic wind.
