Multiple choice commercial applications issues of the environment excessive consumption of resources atmosphere and its components atmosphere- wind

The sea breeze is caused due to the low pressure generated over

  1. Land

  2. Sea

  3. Air

  4. Both A and B
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

During, the daytime when the air above the land gets heated up, the air molecules absorbs the heat and the intermolecular forces between the air molecules become weak and its kinetic energy increases. The air molecules move apart and become less dense and they become lighter and rises up. This creates a low-pressure zone on land and thus cold air from the sea rushes from sea to land and thus creates sea breeze.

So, the correct answer is option B.

Suppose it is a winter night and at about 11 p.m., the air cools to the dew-point temperature and a thick radiation fog develops. If the air continues to cool during the night, in 5 hours the dew point temperature will probably:

  1. Decrease as the air becomes drier

  2. Decrease as the air becomes moister

  3. Increase as the air becomes drier

  4. Increase as the air becomes moister
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

As the air cools further during the night, water vapor condenses out of the air to form fog. This removal of water vapor decreases the dew point temperature.

Where are the days and nights of equal length all year long?

  1. At $66.5^{o}$

  2. Nowhere
  3. At $23.5^{o}$

  4. At the Equator
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Equator receives approximately equal day and night lengths throughout the year because it is positioned such that the sun's path remains consistent relative to the horizon.

Typically, water vapor occupies about what percentage of the air's volume near the earth's surface?

  1. About 78 percent

  2. About 21 percent

  3. Close to 10 percent

  4. Less than 4 percent
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water vapor is a variable gas in the atmosphere, typically ranging from 0 to 4 percent by volume depending on temperature and location. It is most concentrated near the surface in tropical regions.

At which latitude heat gain through insolation approximately equals heat loss through terrestrial radiation:

  1. $22.5^0$ North and South
  2. $40^0$ North and South
  3. $42.5^0$ North and South
  4. $66^0$ North and South
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Heat gain from solar insolation approximately balances heat loss from terrestrial radiation around the 40 degree latitude lines in both the Northern and Southern Hemispheres. Lower latitudes receive a net surplus of energy, while higher latitudes experience a net deficit.

If climate change keeps on disrupting atmospheric pressure, it would bring ice age in

  1. America

  2. Northern Europe

  3. Africa

  4. Canada
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Disruption of the North Atlantic Current, often linked to climate change, could lead to a significant cooling effect in Northern Europe. This is a common hypothesis regarding the impact of melting Arctic ice on ocean circulation.

Which of the following statements is not correct?

  1. The length of human hair changes as the relative humidity changes.

  2. During the winter, low relative humidity can irritate the mucus membranes in the nose and throat.

  3. The relative humidity is a measure of the air's actual water vapor content.

  4. A change in the air temperature can change the relative humidity.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Relative humidity is defined as the ratio of the actual water vapor content to the maximum possible water vapor content at a given temperature. It is not a direct measure of the actual vapor content itself, which is defined by absolute humidity or vapor pressure.

The relative humidity is often near 100 percent in the Polar Regions.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In Polar Regions, the air is extremely cold, which significantly lowers the air's capacity to hold water vapor. Consequently, even small amounts of moisture result in high relative humidity, often reaching saturation levels near 100 percent.

If the air temperature increased, with no addition or removal of water vapor, the actual vapor pressure would:

  1. Increase

  2. Decrease

  3. Stay the same

  4. Become greater than the saturation vapor pressure
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Actual vapor pressure is a measure of the amount of water vapor in the air. If the temperature increases but no water vapor is added or removed, the amount of water vapor remains constant, and thus the actual vapor pressure stays the same.
