26. Which one of the following is the only riverine major port in India?

Correct Answer: (c) Kolkata
Solution:The Kolkata Port (KoPT), located on the left bank of Hugli River is the first major as well as the only riverine port in India. The Haldia Dock Complex (HDC) is located on the right bank of the river at the confluence of Haldi and Hugli rivers. It has longest approach Channel of 145 km.

27. Which one of the following is not a desert river?

Correct Answer: (a) Barak
Solution:The Barak River flows 900 kilometres (560 mi) through the states of Manipur, Nagaland, Mizoram and Assam in India and into the Bay of Bengal via Bangladesh. The principal tributaries are all in India: the Sonai (or Tuirial), the Jiri, the Tlawng (or Dhaleswari, or Katakal), the Jatinga, the Longai and the Madhura.

28. The heaviest rocks, which are rolled the river bed in river bed in river transport, come under which type of load?

Correct Answer: (d) Traction load
Solution:There are 3 types of sediment load in the river: dissolved, suspended, and bed load. The dissolved load is made up of the solutes that are generally derived from chemical weathering of bedrock and soils. Fine sands, clay, and silt are typically transported as suspended load. Traction is the geologic process whereby a current transports larger, heavier rocks by rolling or sliding them along the bottom. Thus, the grains and clasts interact with the substratum during transport. Traction is where large stones or boulders in the river's load are rolled along by the force of the river.

29. Which of the following factors are needed for the growth of corals?

1. Freshwater

2. Clear shallow salt water

3. Plenty of sunlight for photosynthesis

4. Warm water between 23 °C to 25 °C

Select the correct answer using the code given below.

Correct Answer: (b) 2, 3 and 4 only
Solution:Sunlight: Corals need to grow in shallow water where sunlight can reach them. Corals depend on the algae that grow inside them for oxygen and other things, and since these algae need sunlight to survive, corals also need sunlight to survive. Corals rarely develop in water deeper than 165 feet (50 meters).

Clear water: Corals need clear water that lets sunlight through; they don't thrive well when the water is opaque. Sediment and plankton can cloud water, which decreases the amount of sunlight that reaches the zooxanthellae.

Warm water temperature: Reef-building corals require warm water conditions to survive. Different corals living in different regions can withstand various temperature fluctuations. However, corals generally live in water temperatures of 68 - 90° F or 20 – 32° C.

Clean water: Corals are sensitive to pollution and sediments. Sediment can create cloudy water and be deposited on corals, blocking out the sun and harming the polyps. Wastewater discharged into the ocean near the reef can contain too many nutrients that cause seaweeds to overgrow the reef.

Saltwater: Corals need saltwater to survive and require a certain balance in the ratio of salt to water. This is why corals don't live in areas where rivers drain fresh water into the ocean ("estuaries").

30. Convection currents, which move the tectonic plates, are found in which layer of the earth?

Correct Answer: (b) Mantle
Solution:
  • The Mantle is the middle layer of the earth surface extending up to 2900 kilometers.
  • Beneath the Mantle lies the core which contains molten rocks and materials called magma.
  • The materials are highly radioactive and immensely heated. These highly hot condition creates pressure on the middle layer (Mantle).
  • As a result, large convention currents are generated excessively.
