Consider the following statements
1. The annual range of temperature is greater in the Pacific Ocean than that in the Atlantic Ocean.
2. The annual range of temperature is greater in the Northern hemisphere than that in the Southern hemisphere.

Which of the statements given above is/are correct?

  1. Only 1

  2. Only 2

  3. Both 1 and 2

  4. Neither 1 nor 2

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

Statement 1 is incorrect because the Atlantic Ocean has a greater annual temperature range than the Pacific due to its smaller size and greater influence of landmasses. Statement 2 is correct because the Northern Hemisphere has significantly more land area than the Southern Hemisphere, leading to greater temperature fluctuations.

Which one among the following best explains the reason for the Eastern and Western boundaries of the Pacific Ocean experiencing frequent earthquake?

  1. There are deep ocean trenches along these margins

  2. High mountain stretch along the continental margins adjacent to this ocean

  3. These margins coincide with the plate margins

  4. The currents of the vast Pacific Ocean continue to dash against the continental margins

C Correct answer
Explanation

The Pacific Ocean is surrounded by the Ring of Fire, where major tectonic plates meet. These plate boundaries are the primary source of the frequent seismic and volcanic activity observed along the Pacific margins.

Which one of the following factors is responsible for change in the regular direction of the ocean currents in the Indian Ocean?

  1. Indian Ocean is half an ocean

  2. Indian Ocean has Monsoon drift

  3. Indian Ocean is a land-locked ocean

  4. Indian Ocean has greater variation in salinity

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

The Indian Ocean currents are unique because they reverse direction seasonally due to the influence of the monsoon winds. This phenomenon is known as the Monsoon Drift.

Which of the following currents is located near the coastline of Philippines and China?

  1. Oyashio current

  2. Kuroshio current

  3. Canary current

  4. Benguela current

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

The Kuroshio Current is a warm, north-flowing ocean current on the west side of the North Pacific Ocean, which flows past the coast of Taiwan, Japan, and the Philippines.

Consider the following statements:
I. Ocean currents are large mass of surface water, that circulate in regular patterns around the oceans.
II. The planetary winds are probably the dominant influence on the flow of ocean currents.
III. The water of high salinity are denser than the water of low salinity.
IV. A land mass always obstructs and diverts an ocean current.
Which of the statements given above is/are correct?

  1. All of these

  2. I, II and III

  3. I and III

  4. Only II

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

All statements are correct: I defines currents, II identifies wind as the primary driver, III correctly notes that salinity increases density, and IV identifies that landmasses act as barriers to current flow.

The acidification of oceans is increasing. Why is this phenomenon a cause of concern?

1. The growth and survival of calcareous phytoplankton will be adversely affected.
2. The growth and survival of coral reefs will be adversely affected.
3. The survival of some animals that have phytoplanktonic larvae will be adversely affected.
4. The cloud seeding and formation of clouds will be adversely affected.
Which of the statements given above is/are correct? 

  1. 1, 2 and 3

  2. Only 2

  3. 1 and 3

  4. 1, 2, 3 and 4

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

Ocean acidification reduces carbonate ion availability, harming calcifying organisms like phytoplankton and corals (1, 2). Larval stages are sensitive to chemical changes (3). Furthermore, reduced phytoplankton productivity can impact dimethyl sulfide production, which is involved in cloud formation (4).

Consider the following statements with reference to the continental shelf:
1. It is submerged in water. 
2. Its average depth is 100 fathoms.
3. Its higher percentage is found in the Pacific ocean.
4. It is wider, where high mountains are close and parallel to the coast.
Which of the statements given above is/are correct?

  1. All of the below

  2. 1, 2 and 3

  3. 1 and 2

  4. Only 1

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

The continental shelf is submerged (1) and its average depth is indeed about 100 fathoms (2). Statement 3 is incorrect as the Atlantic has a larger percentage of continental shelves. Statement 4 is incorrect because shelves are generally narrow where mountains are close to the coast.

Which of the following factors affects the origin and nature of movement of ocean current?

  1. Gravitational force

  2. Density differences

  3. Direction and shape of coastline

  4. All of the above

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

Ocean currents are influenced by a combination of factors including gravitational forces, density differences (thermohaline circulation), and the physical shape of coastlines which deflects flow.
