Question 101. Assertion (A):
Unlike temperate forests, the tropical rain forests, if cleared, can yield productive farmland that can support intensive agriculture for several years even without chemical fertilizers.
Reason (R):
The primary productivity of the tropical rain forest is very high compared to that of temperate forests.

Answer: Option C. -> (A) is false, but (R) is true
Answer: (c)
Answer: (c)
Answer: Option D. -> India
Answer: (d)
Answer: (d)
Answer: Option D. -> Typhoon
Answer: (d)
Tropical Cyclones (also known as Typhoons (in the western Pacific), Hurricanes (Atlantic), or Tropical Revolving Storms) occur all year round over the northern South China Sea.
However, the “Typhoon Season” is taken to be from the Autumn transition (Oct) to the first half of the Northeast monsoon (NovDec), when they occur most frequently in the South China Sea.

Answer: Option A. -> saturation point
Answer: (a)
Answer: (a)
Answer: Option B. -> Winds blowing in southern hemisphere between 400– 600 S
Answer: (b)
The Roaring Forties is the name given to strong westerly winds found in the Southern Hemisphere, generally between the latitudes of 40 and 50 degrees.
The strong west-to-east air currents are caused by the combination of air being displaced from the Equator towards the South Pole and the Earth's rotation, and there are few landmasses to serve as windbreaks.

Answer: Option A. -> Norway
Answer: (a)
Answer: (a)
Answer: Option D. -> Troposphere, Stratosphere, Mesosphere, Ionosphere.
Answer: (d)
The troposphere is the lowest portion of Earth’s atmosphere and is also where all weather takes place.
The stratosphere is a layer of Earth’s atmosphere. It is the second layer of the atmosphere as one go upward. About 20% of the atmosphere’s mass is contained in the stratosphere. The stratosphere is stratified in temperature, with warmer layers higher and cooler layers closer to the Earth.
The region of the earth’s atmosphere above the stratosphere and below the thermosphere, between about 50 and 80 km in altitude is Mesosphere. In the mesosphere, temperature decreases as the altitude increases. The ionosphere is defined as the layer of the Earth’s atmosphere that is ionized by solar and cosmic radiation. It lies 75-1000 km (46-621 miles) above the Earth.

Answer: Option B. -> Temperate Coniferous forests
Answer: (b)
Answer: (b)
Answer: Option B. -> 30º
Answer: (b)
Answer: (b)
Answer: Option D. -> tropopause
Answer: (d) Jet streams are fast flowing, narrow air current found in the atmospheres of some planets including Earth. The main jet streams are located near the tropopause, the transition between the tropopause, the transition between the troposphere and the stratosphere.
