As the speed of the wind increases, the strength of the wave ____________.

  1. increase

  2. decrease

  3. remains same

  4. became calm

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Waves in the sea surface are generated by the action of the wind. The height of the wind waves increases with the increasing wind speed and with increasing duration and fetch of the wind. As the speed of the wind increases, the strength of the wave also increases.

Multiple choice geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

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

Reveal answer Fill a bubble to check yourself
C Correct answer
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.

Multiple choice geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

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

  1. Air

  2. Water

  3. Both a and b

  4. none of these

Reveal answer Fill a bubble to check yourself
A Correct answer
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.

Multiple choice geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

Temperature decreases down the valleys, it is known as the _______.

  1. Inversion of temperature

  2. Inversion of heat

  3. Inversion of pressure

  4. none of these

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Temperature decreases down the valley, it is known as the inversion of temperature. Especially during the winter nights the temperature increase with the altitude. This is mainly due to rapid radiation from the ground and on account of the flow of heavy cold air down the valley.

Multiple choice geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

Temperature of the atmosphere and altitude are _____.

  1. interrelated

  2. different

  3. same

  4. none of these

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A temperature of the atmosphere and altitude are interrelated. The temperature of the atmosphere decrease with increasing altitude from the earth's surface. This vertical decrease in temperature of the atmosphere is limited to the troposphere. The atmosphere is heated mainly from below. Therefore, within the troposphere, as we go higher temperature gradually decreases to about 6.5 degrees C per km. Sometimes, especially during cold winter nights the temperature increase with the altitude. This is mainly due to the rapid radiation from the ground and on account of the flow of heavy cold air down the valley.

Multiple choice geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

Temperature varies from place to place with latitude and altitude. It may increase or decrease depending upon the factors that affect temperature. Certain anomalies may also develop on account of tmique combination of factors. The inversion of temperature would mean that the _____________.

  1. Temperature decreases with elevation

  2. Temperature is constant at different eleations

  3. Temperature decreases and then increases with elevation

  4. Temperature changes along the same latitude

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Temperature inversion is a phenomenon where the normal temperature gradient is reversed, meaning temperature increases with altitude instead of decreasing.

Multiple choice geography natural regions climate and natural vegetation equatorial climatic region natural regions of the world

The humidity in the equatorial forest region is __________.

  1. very high

  2. high

  3. moderate

  4. low

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The equatorial forest region experience very high temperatures throughout the year, the annual average temperature is being about 27 degrees celsius. The daily range of temperature is between 10 degrees Celsius to 25 degrees celsious. The rainfall is very heavy and distributed throughout the year. This region also received a sufficient amount of sunshine for all these the humidity level is very high in this region.

Multiple choice physics the kinetic model of matter gases and the kinetic theory concept of ideal gas and state equation of ideal gas behaviour of perfect gas and kinetic theory of gases

A drop of alcohol is introduced into the vaccum space of mercury barometer completely evaporates and then slightly lowers the height of the barometer. If the barometer tube is raised from this position, the height of the barometer will

  1. fall

  2. rise

  3. remains stationery

  4. falls first and then rises

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Since on raising the tube, the volume of vacuum will decrease and hence pressure due to alcohol will decrease. Since the pressure at the base must be equal to atmospheric pressure, to compensate for the decrease in pressure due to alcohol expansion, mercury in tube will rise but will never reach 76mm since pressure due to vaporized alcohol will never be 0.

Multiple choice chemistry states of matter: boiling, evaporation and condensation atmospheric pressure and boiling point evaporation - factors and effects in daily life changes in physical state - boiling, evaporation and condensation

During hot sunny day, people sprinkle water on the roof because ______________.

  1. they have more water to sprinkle

  2. water is cheapest thing available

  3. it has high latent heat of vapourisation

  4. None of the above

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

People sprinkle water on the roof top during sunny days as water has high latent heat of vaporisation so it will absorb more heat and make the roof top cool.

On decreasing the surface area, the rate of evaporation _________.

  1. increases

  2. decreases

  3. remains same

  4. Data insufficient

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

On decreasing the surface area, fewer particles are exposed to the atmosphere. So the rate of evaporation decreases.
