Questions Related to sun: the ultimate source

___________ which fall over the Torrid Zone travel shorter distance and heat up a smaller surface leading to higher temperature.

  1. The sun's rays

  2. The moon's rays

  3. The mars's rays

  4. none of these


Correct Option: A
Explanation:
The sun's rays which fall over the Torrid Zone travel shorter distances and heat up a smaller surface leading to higher temperatures.
The spectrum of the Sun's solar radiation is close to that of a black body with a temperature of about 5,800 K. The Sun also emits X-rays, ultraviolet, visible light, infrared, and even radio waves; the only direct signature of the nuclear process is the emission of neutrinos.

The mechanism to maintain same temperature by the atmosphere is called as _____________. 

  1. Heat Budget

  2. Heat Balance

  3. Both a and b

  4. None of these


Correct Option: C
Explanation:

Heat budget and Heat Balance.

The earth as a whole does not accumulate or lose heat. It maintains its temperature. This can happen only if the amount of heat received in the form of insolation equals the amount lost by the earth through terrestrial radiation.

The height of a place above the mean sea level is known as its _________.

  1. altitude

  2. latitude

  3. both a and b

  4. none of these


Correct Option: A

Temperature __________ with ____________ in latitude on either side of the Equator due to spherical shape of the earth and its annual revolution around the sun.

  1. increases, decrease

  2. decreases, increase

  3. improves, decrease

  4. none of these


Correct Option: B
Explanation:
  • Temperature decreases with the increase in latitude on either side of the equator as the spherical shape of the earth and its revolution around the sun along with its tilted orbit leads to the reduction in the amount the insolation received as we move away from the equator. Hence option B is correct.

Slope of the land influences the ___ of a place.

  1. temperature

  2. pressure

  3. heat

  4. none of these


Correct Option: A

___________ is cooler at higher altitudes than on the earth's surface.

  1. Air

  2. Water

  3. Both a and b

  4. none of these


Correct Option: A
Explanation:

Air,

At higher altitudes, the air is thinner.  Without this atmosphere, Earth would be uninhabitable cold. So, even though higher altitude areas are closer to the sun, they have less ability to absorb the warmth of the sun because they have less of these gases.

During the _____ , the land is hotter than the sea.

  1. day

  2. night

  3. evening

  4. none of these


Correct Option: A
Explanation:

Day,

Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. Now, recall that warmer air is lighter than cooler air.

Cool breeze that blows over the earth is known as ________.

  1. Water breeze

  2. sea breeze

  3. heat breeze

  4. none of these


Correct Option: B
Explanation:

During the day time, land gets heated more than the adjacent sea and low pressure develops over the land. The warm air over the land being lighter moves upward and its place is taken over by the cooler air coming from the sea. This is called Sea Breeze.

Tick the correct answer:
The frigid zone lies near:

  1. the Poles

  2. the Equator

  3. the Tropic of Cancer

  4. None of these


Correct Option: A
Explanation:

The Frigid Zone lies near the Poles. The climate in the Polar Regions is very cold that is why the area is known as the Frigid Zone.

Maximum Point on Fahrenheit scale is ____________.

  1. 232$^{o}$F

  2. 212$^{o}$F

  3. 273$^{o}$F

  4. 373$^{o}$F


Correct Option: B
