2. Question
2 points
1. The western coastal plains are an example of submerged coastal plain.
2. Because of this submergence it is a narrow belt and doesn’t provides natural conditions for the
development of ports and harbours.
3. Mazagaon, JLN port Navha Sheva, Marmagao, Mangalore, Cochin, etc. are some of the important natural
ports located along the west coast.
Select the correct answer using the code below
• The western coastal plains are an example of submerged coastal plain. It is believed that the city of
Dwaraka which was once a part of the Indian mainland situated along the west coast is submerged
under water. Because of this submergence it is a narrow belt and provides natural conditions for the
development of ports and harbours. Kandla, Mazagaon, JLN port Navha Sheva, Marmagao,
Mangalore, Cochin, etc. are some of the important natural ports located along the west coast.

4. Question
2 points
1. Coastal lagoons generally form near flat or gently sloping landscapes.
2. The size and depth of coastal lagoons often depend on sea level.
Which of the above is/are correct?
• A lagoon is a shallow body of water protected from a larger body of water (usually the ocean) by
sandbars, barrier islands, or coral reefs. Lagoons are often called estuaries, sounds, bays, or even
lakes.
• Statement 1: Lagoons sheltered by sandbars or barrier islands are called coastal lagoons. Coastal
lagoons form along coastal plains—flat or gently sloping landscapes. They form in areas with small
tidal ranges. Coastal lagoons are created as a shallow basin near the shore gradually erodes, and the
ocean seeps in between the sandbars or barrier islands.
• Statement 2: The size and depth of coastal lagoons often depend on sea level. When the sea level is
low, coastal lagoons are swampy wetlands. When the sea level is high, they can look like coastal lakes
or bays.

6. Question
2 points
1. Saline water
2. Absence of tides
3. Muddy anaerobic soil
Select the correct answer using the codes below.
• Mangroves are plants that survive high salinity, tidal regimes, strong wind velocity, high temperature
and muddy anaerobic soil—a combination of conditions hostile for other plants.In fact, Mangroves
grow best in inter-tidal regions of sheltered shores, estuaries, creeks, backwaters, lagoons, marshes
and mud-flats. So, statement 2 is clearly incorrect.
• The mangrove ecosystems constitute a symbiotic link or bridge between terrestrial and marine
ecosystem.
• Mangrove vegetation has been reported in all the coastal states/UTs. India is home to some of the best
mangroves in the world. West Bengal has the maximum mangrove cover in the country, followed by
Gujarat and Andaman and Nicobar Islands.
• However, not all coastal areas are suitable for mangrove plantation as these plants require an
appropriate mix of saline and freshwater, and soft substrate like mudflats to enable it to grow and
perpetuate.

7. Question
2 points
• Option C: The intertidal zone, also known as the foreshore and seashore and sometimes referred to as
the littoral zone, is the area that is above water at low tide and under water at high tide. So, C is
incorrect.
Option B: Water is available regularly with the tides but varies from fresh with rain to highly saline and dry
salt with drying between tidal inundations. So, B is incorrect.
It is very rich in nutrients and hence supports the growth of Mangroves the best

8. Question

promote the growth of seaweeds?
1.Shallow coastal waters with high temperature
2.Sandy ocean bottoms and clear water
3.Ocean water frequently disturbed by strong waves and currents
Select the correct answer using the codes below.
• Statement 1: A water temperature ranging from 25 °C to 30 °C is best for growing seaweed. In
shallow waters near the beach, the water temperature can become quite high especially during a sunny
day. Such an area is not suitable for planting seaweed.
• Statement 2: Fresh water kills seaweed. But, Seaweed prefers clear saline water and plenty of sunlight,
even turbid water (muddy) will not sustain good seaweed growth.
• Statement 3: If the water current is too strong, it can damage your plants and even wash away your
planted lines by pulling down the stakes.
• They are the only group of higher plants adapted to life in the salt water. Major Sea grass meadows in
India occur along the south east coast of Tamil Nadu, in the lagoons of a few Lakshadweep Island and
Andaman and Nicobar islands.
• The strong photosynthesis of algae creates a large affinity for nutrients; this allows the seaweed to be
used purposely to remove undesired nutrients from water. Other seaweed may be used as fertilizer,
compost for landscaping, or a means of combating beach erosion through burial in beach dunes.

9. Question

the following implications?
1.No potential fisheries zone is found in Gujarat coasts.
2.The shelf provides a rich ground for hydrocarbon extraction.
Which of the above is/are correct?
• Statement 1: This isn’t correct. Gujarat also ranks second in having backwaters, next only to Bengal,
which has huge potential for fisheries. Moreover, continental shelves make delta formation easier and
encourage growth of transition (freshwater and saline water) marine species.
• Statement 2: Most commercial exploitation from the sea, such as metallic-ore, non-metallic ore, and
hydrocarbon extraction, takes place on the continental shelf. This is due to the large sedimentation
from rivers that form delta there.

10. Question
2 points
1.The density of seawater is unbearable to freshwater organisms resulting in their reverse migration.
2.The phenomenon of osmosis can augur dangerous for freshwater animals.
Which of the above is/are correct?
• Freshwater animals cannot live for long in sea water as well as many sea water animals also cannot
live for long in freshwater.
• If a freshwater animal is put in salt water, the salty sea water would absorb the water from the animal
via its gills due to osmosis until it dies.
• The opposite happens to a saltwater animal placed in fresh water. It instead absorbs too much
freshwater through its gills due to reverse osmosis and dies as a result.
• Some animals, for e.g. fish can live in both fresh and salt water (salmon, eels, bull sharks for instance)
but they require time to adjust between the two
