Question 1 of 5
1. Question
Delays in the formation of Mascarene High can lead to:
Correct
Answer: The correct option is B.
Explanation:- Mascarene High: This high-pressure region located between 25°S-35°S and 40°E-90°E near the Mascarene Islands in the southern Indian Ocean is a source of Southwest monsoon in India. Since it is a high pressure area, it is also known as Mascarene high. This is responsible for cross- equatorial flow through south Arabian Sea and it acts as southern hemispheric linkage. The variation in the intensity of High Pressure causes monsoon surges across equatorial flow. These surges are responsible for heavy rains along the west coast.
If there is a delay in the formation of Mascarene High there is a possibility of delay in the onset of Indian Monsoon.

Question 2 of 5
2. Question
Match the following:
Drainage pattern Characteristics
Dendritic 1. Rivers originate from a hill or mountain and flow in all directions, like the spokes of a wheel.
Radial 2. Resembles the branches of a tree, with the main river channel and its tributaries forming a network that spreads out across the landscape.
Trellis 3. Rivers discharge their waters from all directions into a lake or depression in the center of a circular or elliptical basin.
Centripetal 4. Primary tributaries of a river flow parallel to each other and are joined by secondary tributaries at right angles.Choose the correct option:
Correct
Answer: The correct option is B.
Explanation:- Dendritic pattern: Resembles the branches of a tree, with the main river channel and its tributaries forming a network that spreads out across the landscape.
- Radial pattern: Rivers originate from a hill or mountain and flow in all directions, like the spokes of a wheel.

Question 3 of 5
3. Question
Consider the following statements:
1. The jet streams are easterly winds of the stratosphere.
2. Jet Streams blow at the same speed throughout the year.
Which of the following statements is/are correct?Correct
Answer: The correct option is D.
Explanation: The term “jet stream” refers to a narrow band of westerly winds flowing at a high altitude (above 12000m).
From approx. 110 km/h in the summer to about 184 km/h in the winter, their speed varies.Incorrect

Question 4 of 5
4. Question
Consider the following:
Volcanoes Description
a. Composite volcanoes 1.These are tall, steep-sided volcanoes that are formed from basaltic lava flows. The lava of composite volcanoes has higher viscosity.
b. Shield volcanoes 2. These are broad, gently sloping volcanoes that are typically formed from basaltic lava flows.
c. Fissure volcanoes 3. These are small, steep-sided volcanoes that are formed from explosive eruptions of gas-rich magma.
d. Cinder volcanoes 4. These are long, narrow volcanoes that are formed when lava erupts from a crack in the earth’s crust.Which of the following pairs are correctly matched:
Correct
Answer: The correct option is A.
Explanation:
- Composite volcanoes: These are tall, steep-sided volcanoes that are formed from basaltic lava flows. The lava of composite volcanoes has higher viscosity.
- Shield volcanoes: These are broad, gently sloping volcanoes that are typically formed from basaltic lava flows.
- Fissure volcanoes: These are long, narrow volcanoes that are formed when lava erupts from a crack in the earth’s crust. Fissure eruptions can produce large amounts of basaltic lava, which can flow for long distances.
Cinder volcanoes: These are small, steep-sided volcanoes that are formed from explosive eruptions of gas-rich magma. The eruptions produce cinders, which are small pieces of volcanic rock.
