With respect to thermocline, choose the correct statement:
1. Layer in which temperature changes more rapidly than it does in layers above as below.
2. It depends upon season, latitude and turbulent mixing by wind.
3. It may be semi-permanent feature of body of water in which they occur.

  1. 1 only

  2. 1 and 2 only

  3. 3 only

  4. all of them

D Correct answer
Explanation

The thermocline is a transition layer where temperature drops rapidly with depth. Its depth and intensity are influenced by seasonal changes, latitude, and wind-driven mixing, and it often acts as a semi-permanent feature in the water column.

Which among the following statements about the North Atlantic Drift is/are correct?
1. It keeps the West coast of Northern Europe ice free.
2. It is responsible for the warm air mass which interacts with the cold air mass from the Polar region and causes rainfall in Western Europe.
3. It meets the Labrador current near Vancouver Island and causes dense fog.

Select the correct answer using the - codes given below

  1. 1, 2 and 3

  2. 1 and 2

  3. Only 2

  4. 1 and 3
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The North Atlantic Drift keeps Northern Europe ice-free (1) and influences the climate by bringing warm air (2). Statement 3 is incorrect because the North Atlantic Drift does not meet the Labrador current near Vancouver Island; that meeting occurs in the North Atlantic off the coast of Newfoundland.

Tides are of various types, caused by different alignments of Sun, Moon and Earth. Choose correct statement.
1. Height of high tide and low tides at different places in different oceans, differs. 
2. At perigee, spring tide gets abnormally high.
3. Same place will have another spring tide after 12 hours exactly.

  1. Only 1

  2. 1 and 2

  3. 1 and 3

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

Tide heights vary by location due to basin shape (1). Perigee (when the moon is closest to Earth) increases the gravitational pull, leading to higher spring tides (2). Statement 3 is incorrect because the interval between high tides is roughly 12 hours and 26 minutes, not exactly 12 hours.

Which of the following statements relating to tsunami is/are correct?
As the tsunamis leave the deep water of the open sea and travel towards shallow water:
1. The speed is reduced considerably.
2. They attain enormous height.
3. They appear as a gentle rise and fall of the sea.

Select the correct answer using the codes given below.

  1. 1 and 2

  2. 2 and 3

  3. Only 1

  4. All of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

As tsunamis enter shallow water, their speed decreases due to friction, and their energy is compressed into a smaller volume, causing the wave height to increase significantly. Statement 3 is incorrect because tsunamis are not just gentle rises and falls; they are powerful, destructive surges.

The interval between two high tides is approximately _________.

  1. 4 h 12 m

  2. 6 h 13 m

  3. 12 h 26 m

  4. 24 h 52 m
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Earth rotates once in 24 hours, but the moon also orbits the Earth in the same direction. This makes the lunar day about 24 hours and 52 minutes long, resulting in high tides occurring roughly every 12 hours and 26 minutes.

On the planet Earth, most of the fresh water exists as ice caps and glaciers. Out of the remaining fresh water, the largest proportion _____________.

  1. is found in atmosphere as moisture and clouds

  2. is found in freshwater lakes and rivers

  3. exists as groundwater

  4. exists as soil moisture
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

After ice caps and glaciers, the largest reservoir of fresh water on Earth is groundwater, which accounts for a significant portion of the remaining liquid fresh water.

Extensive coral formations develop between 30°N and 30°S especially on the sides of the landmasses.

  1. Eastern

  2. Western

  3. Northern

  4. Southern
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coral reefs are more extensive on the eastern sides of continents in tropical regions because the western sides of ocean basins have cold currents that inhibit coral growth, while the eastern sides have warm currents.
