When the air is saturated, which of the following statements is NOT correct?

  1. The air temperature equals the wet-bulb temperature

  2. The relative humidity is 100 percent

  3. The air temperature equals the dew point temperature

  4. An increase in temperature will cause condensation to occur

D Correct answer
Explanation

When air is saturated, relative humidity is 100 percent and the dew point equals the air temperature. Increasing the temperature would decrease the relative humidity, not cause condensation.

What scale is useful to record the force of wind ?

  1. Decibel

  2. Richter

  3. Beau fort

  4. Fajita

C Correct answer
Explanation

The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. It ranges from 0 (calm) to 12 (hurricane-force winds). Decibels measure sound intensity, Richter scale measures earthquake magnitude, and Fujita scale (misspelled as Fajita here) measures tornado intensity.

World climate is threatened by increase in atmospheric concentration of

  1. Oxygen

  2. Nitrogen

  3. Water vapours

  4. Carbon dioxide

  5. Both C and D
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

The major greenhouse gases are water vapour, which causes about 3670% of the greenhouse effect; carbon dioxide (CO$ _2$), which causes 926%; methane (CH$ _4$), which causes 49%; and ozone (O$ _3$), which causes 37%. Water vapour is the most abundant greenhouse gas, it acts as a feedback to the climate. Water vapour increases as the earth's atmosphere warms, making these the most important feedback mechanisms to the greenhouse effect. Carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels. This is the most important long-lived cause of climate change.

Therefore, the correct answer is option C and D.

Gaseous envelop surrounding the earth is called

  1. Lithosphere

  2. Mesophere

  3. Stratosphere

  4. Atmosphere
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The atmosphere is a gaseous envelope surrounding the earth. It is mostly composed of nitrogen, oxygen, argon, carbon dioxide and some other gasses in trace amounts. The atmosphere is held in place by gravity of the earth.    Thus the correct answer is option D.
