Question 1 of 5
1. Question
Consider the following statements about Polar vortex.
- The polar vortex is a large area of high pressure and cold air surrounding the Earth’s North and South poles.
- The polar vortex spins in the stratosphere.
- During winter in the Northern Hemisphere, the polar vortex will become less stable, sending cold Arctic air southward over the United States.
Which of the above statements is/are correct?
Correct
Solution: b)
The polar vortex is a large area of low pressure and cold air surrounding the Earth’s North and South poles. The term vortex refers to the counter-clockwise flow of air that helps keep the colder air close to the poles.
The polar vortex spins in the stratosphere, a layer of the atmosphere 10-48 km above the ground and above the troposphere, where most familiar weather patterns develop.
Often during winter in the Northern Hemisphere, the polar vortex will become less stable and expand, sending cold Arctic air southward over the United States.

Question 2 of 5
2. Question
Consider the following statements:
- These are the most widespread forests in India
- They spread over regions which receive rainfall between 70-200 cm
- These forests are also found in the north-eastern states along the foothills of Himalayas
The above statements are related to:
Correct
Solution: b)
Tropical Deciduous Forests:
These are the most widespread forests in India. They are also called the monsoon forests. They spread over regions which receive rainfall between 70-200 cm. On the basis of the availability of water, these forests are further divided into moist and dry deciduous.
The Moist deciduous forests are more pronounced in the regions which record rainfall between 100-200 cm. These forests are found in the north-eastern states along the foothills of Himalayas, eastern slopes of the Western Ghats and Odisha.

Question 4 of 5
4. Question
Consider the following statements.
- The distance between two longitudes decreases towards the poles whereas the distance between two latitudes remains the same everywhere.
- The latitudinal and longitudinal extent of India are roughly about 30 degrees, whereas there is a difference of around 200 kms in the actual distance measured from north to south extremity and that from east to west.
Which of the above statements is/are correct?
Correct
Solution: c)
If you work out the latitudinal and longitudinal extent of India, they are roughly about 30 degrees, whereas the actual distance measured from north to south extremity is 3,214 km, and that from east to west is only 2,933 km.
This difference is based on the fact that the distance between two longitudes decreases towards the poles whereas the distance between two latitudes remains the same everywhere.

Question 5 of 5
5. Question
Consider the following statements
- The soil is developed in the region of high temperature
- They are poor in organic matter
- They are cut as bricks for construction
- They are commonly found in Karnataka, Tamil Nadu and Madhya Pradesh
The above statements are related to:
Correct
Solution: c)
Laterite Soil:
The laterite soils develop in areas with high temperature and high rainfall. Humus content of the soil is removed fast by bacteria that thrives well in high temperature. These soils are poor in organic matter, nitrogen, phosphate and calcium, while iron oxide and potash are in excess.
Laterite soils are widely cut as bricks for use in house construction. These soils have mainly developed in the higher areas of the Peninsular plateau. The laterite soils are commonly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh and the hilly areas of Odisha and Assam.
