In which layer of atmosphere temperature remains constant?

  1. Mesosphere

  2. Thermosphere

  3. Stratosphere

  4. Troposphere
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In the stratosphere, the temperature increases with altitude due to ozone absorption of UV radiation, but there are regions where the temperature gradient is near zero or stable, often contrasted with the troposphere's lapse rate.

Which is second major layer of earth's atmosphere?

  1. Troposphere

  2. Mesosphere

  3. Thermosphere

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

The layers of the atmosphere starting from the surface are: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Therefore, the stratosphere is the second layer.

C Correct answer
Explanation

The troposphere is the lowest layer of the Earth's atmosphere, extending from the surface up to the tropopause.

Cyclones are mainly caused by 

  1. High-speed wind

  2. Diferential air pressure

  3. Uneven heating of land

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The cyclone is the circulating mass of air that rotates around the center of low atmospheric pressure. It is caused due to uneven heating of the land. The uneven heating of land causes the difference in the air pressure and causes the strong flow of wind from high pressure to low pressure.

So, the correct answer is option D.

One litre of cold air weighs heavier than the dry air (1 Lit) because of the

  1. Increased number of collisions between the molecules

  2. Increased number of molecules at low temperature

  3. Greater energy of molecules at high temperature

  4. Lower energy of molecules at high temperature

An ordinary clock loses time in summer. This is because

  1. The length of the pendulum increases and time period increases

  2. The length of the pendulum increases and time period decreases

  3. The length of the pendulum decreases and time period increases

  4. The length of the pendulum decreases and time period decreases
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

As temperature increases in summer, the metal pendulum rod undergoes thermal expansion, increasing its length. Since the period of a pendulum is proportional to the square root of its length, a longer pendulum results in a longer time period, causing the clock to run slow.

At which city might you be able to observe cirrus clouds at an altitude of 3,000 m (10,000 feet) above the surface?

  1. Barrow, Alaska

  2. Honolulu, Hawaii

  3. Miami, Florida

  4. Chicago, Illinois
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cirrus clouds are high-altitude clouds. In polar regions like Barrow, Alaska, the tropopause is much lower than in tropical regions, allowing high-altitude clouds to exist at lower absolute altitudes.

Hot spots are regions of high

  1. rarity

  2. endemism

  3. critically endangered population

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

Biodiversity hotspots are biogeographic regions that are both a significant reservoir of biodiversity and are threatened with destruction, characterized by high levels of endemism (species found nowhere else).

The wind-chill factor:

  1. Relates body heat loss with wind to an equivalent temperature with no wind

  2. Indicates the temperature at which water freezes on exposed skin

  3. Takes into account humidity and air temperature in expressing the current air temperature

  4. Tells farmers when to protect crops from a freeze
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The wind-chill factor is a measure of the rate of heat loss from exposed skin due to the combined effects of low temperature and wind speed, expressed as an equivalent temperature.

Heat is energy in the process of being transferred from:

  1. Hot objects to cold objects

  2. Low pressure to high pressure

  3. Cold objects to hot objects

  4. High pressure to low pressure
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Heat is defined as the transfer of thermal energy between systems due to a temperature difference, always flowing from a region of higher temperature to a region of lower temperature.
