Question 2 of 5
2. Question
2 pointsWith reference to International Date Line (IDL), consider the following statements:
- A traveller crossing the IDL from east to west gains a day.
- IDL is an imaginary straight line at 180-degree meridian.
Which of the statements given above is/are correct?
Correct
ANSWER: D
Explanation:
A traveller crossing the IDL from east to west loses a day. IDL is an imaginary zig-zag line at 180-degree meridian. The International Date Line (IDL) is an imaginary line of longitude on the Earth’s surface located at about 180 degrees east (or west) of the Greenwich Meridian. The International Date Line isn’t a fixed line at all, but actually sort of follows the 180° longitude line, zigzagging its way through a bunch of small islands, territories and nations

Question 3 of 5
3. Question
2 pointsWhich of the following is/are examples of chemical weathering?
- Frost action on rocks.
- Repeated wetting and drying.
Select the correct answer using the codes given below.
Correct
ANSWER: D
Explanation:
- Chemical weathering is what happens when rocks are broken down and chemically altered. Frost action and repeated wetting and drying are the process of physical weathering.
- Alternate wetting and drying of rocks, sometimes known as slaking, can be a very important factor in weathering. Slaking occurs by the mechanism of “ordered water”, which is the accumulation of successive layers of water molecules in between the mineral grains of a rock.
- The increasing thickness of the water pulls the rock grains apart with great tensional stress. Recent research has shown that slaking in combination with dissolved sodium sulphate can disintegrate samples of rock in only twenty cycles of wetting and drying.

Question 4 of 5
4. Question
2 pointsThe seismic weaves help in understanding the interior of earth. Which of the following about seismic waves is/are correct?
- P-Waves travel with fastest speed and are most destructive.
- S-Waves are analogous to light waves.
Select the correct answer using the codes given below.
Correct
ANSWER: B
Explanation:
- Though P waves travel with fastest speed, they are not most destructive. L waves are most violent and destructive. S waves that are analogous to light waves because S waves are transverse in the nature and the particle moves at right angles to the direction of propagation.

Correct
ANSWER: C
Explanation:
- Rajaji National Park is spread across Dehradun, Haridwar and Pauri districts of Uttarakhand.
- Kanha National Park located in the upper reaches of Narmada and The Orang National Park, located on the north bank of the Brahmaputra River in the Sonitpur district of Assam
Incorrect
ANSWER: C
