Question 1 of 5
1. Question
Consider the following statements about atmosphere
- The proportion of gases in atmosphere remains the same in general horizontally and vertically
- Water vapour decreases with altitude
Which of the above is/are correct
Correct
Answer – b
- The proportion of gases changes in the higher layers of the atmosphere in such a way that oxygen will be almost in negligible quantity at the height of 120 km.
- Similarly, carbon dioxide and water vapour are found only up to 90 km from the surface of the earth

Question 2 of 5
2. Question
Consider the following about waves
- Waves are fastest at the shores
- The amplitude of waves is lowest in the open ocean
Which of the above is./are correct
Correct
Answer – d
- Waves are actually the energy, not the water as such, which moves across the ocean surface. Water particles only travel in a small circle as a wave passes. Wind provides energy to the waves.
- When a breeze of two knots or less blows over calm water, small ripples form and grow as the wind speed increases until white caps appear in the breaking waves. Waves may travel thousands of km before rolling ashore, breaking and dissolving as surf
- As a wave approaches the beach, it slows down. This is due to the friction occurring between the dynamic water and the sea floor. And, when the depth of water is less than half the wavelength of the wave, the wave breaks. The largest waves are found in the open oceans.

Question 3 of 5
3. Question
Consider the following about waves
- Steep waves are formed by planetary winds mostly
- Water does not move at all when energy passes through it
Which of the above is correct
Correct
Answer – d
- Steep waves are fairly young ones and are probably formed by local wind. Slow and steady waves originate from far away places, possibly from another hemisphere
- The actual motion of the water beneath the waves is circular. It indicates that things are carried up and forward as the wave approaches, and down and back as it passes.

Question 4 of 5
4. Question
Consider the following about the tides
- They are a result of counterbalancing of gravitational forces of celestial bodies only
- Tidal bulges are highest on the continental shelves compare to open ocean
Which of the above is/are correct
Correct
Answer – b
- The moon’s gravitational pull to a great extent and to a lesser extent the sun’s gravitational pull, are the major causes for the occurrence of tides. Another factor is centrifugal force, which is the force that acts to counter balance the gravity
- The tidal bulges on wide continental shelves, have greater height. When tidal bulges hit the mid-oceanic islands they become low.

Question 5 of 5
5. Question
The highest tidal bulge occurs at
Correct
Answer – a
- The highest tides in the world occur in the Bay of Fundy in Nova Scotia, Canada. The tidal bulge is 15 – 16 m. Because there are two high tides and two low tides every day (roughly a 24 hour period); then a tide must come in within about a six hour period. As a rough estimate, the tide rises about 240 cm an hour (1,440 cm divided by 6 hours).
- If you have walked down a beach with a steep cliff alongside (which is common there), make sure you watch the tides. If you walk for about an hour and then notice that the tide is coming in, the water will be over your head before you get back to where you started!
GS 1 – Important Geophysical phenomena
- All the above questions belong to this particular section in GS 1, which basically covers most of the Physical geography. Thus direct questions can be asked in Mains from here, hence static knowledge is significant there.
