QUESTION: 1

### Consider the following statements regarding continental drift theory: 1. It was introduced by Arthur Holmes in 1912. 2. According to the theory, all the continents formed a single continental mass with a mega ocean surrounding it. 3. It failed to give an account of the forces responsible for drifting of the continents. Which of the statements given above is/are correct?

Solution:

Statement 1 is incorrect: It was Alfred Wegener, a German meteorologist who put forth a comprehensive argument in the form of the Continental Drift theory in 1912.

Statement 2 is correct: According to Wegener, all the continents formed a single continental mass and mega ocean surrounding the same. The supercontinent was named PANGAEA, which meant all earth.

Statement 3 is incorrect: Continental Drift theory suggested that the movement responsible for the drifting of the continents was caused by pole-fleeing force and tidal force.

QUESTION: 2

### As per the theory of Plate tectonics, the cycle of convection cell is responsible for the movement of the plates. The sources of heat within the earth responsible for this cycle of convection cells are: 1. Radioactive decay 2. Residual heat from Earth's formation 3. Solar radiation Select the correct answer using the code given below.

Solution:

Statements 1 and 2 are correct:

• As per the Plate tectonic theory, the surface of the earth and the interior are not static and motionless but are dynamic. The mobile rock beneath the rigid plates is believed to be moving circularly.
• The heated material rises to the surface, spreads and begins to cool, and then sinks back into deeper depths. This cycle is repeated over and over to generate what scientists call a convection cell or convective flow. Heat within the earth comes from two main sources: radioactive decay and residual heat.
QUESTION: 3

### Which of the following atmospheric parameters increase as we move up in the mountains? 1. Temperature 2. Density of air 3. Pressure Select the correct answer using the code given below.

Solution:

Statement 1 is incorrect: Temperature decreases with height.

Statement 2 is incorrect: The density of air decreases with height.

Statement 3 is incorrect: Pressure decreases with increasing altitude.

QUESTION: 4

Concerning the  Himalayan and the Peninsular Rivers, consider the following statements
1. Himalayan Rivers are perennial while Peninsular Rivers are seasonal.
2. Himalayan Rivers are old and mature while Peninsular Rivers are youthful in the activity.
3. Unlike Peninsular Rivers, Himalayan Rivers show meandering activity in the plains.

Which of the statements given above is/are correct?

Solution:

Statement 1 is correct: The Himalayan rivers are perennial, i.e., water flows throughout the year in these rivers. These rivers receive water both from the monsoons and snow-melt. While the Peninsular rivers receive water only from rainfall and water flows in these rivers in rainy season only.

Statement 2 is incorrect: Himalayan rivers flow across the young fold mountains and are still in a youthful stage, while Peninsular rivers have been flowing in one of the oldest plateaus of the world and have reached maturity.

Statement 3 is correct: When Himalayan rivers enter the plains, there is a sudden reduction in the speed of flow of water which forms meanders and shifts their beds. While, in the case of Peninsular rivers, the hard rock surface and non-alluvial character of the plateau permits little scope for the formation of meanders. As such, the rivers of the Peninsular Plateau follow more or less straight courses.

3.Tripura
