Why are Airways considered uniquely indispensable during natural disasters like floods, earthquakes, and landslides?
- A
Air travel is the cheapest mode of transport available.
- B
Aircraft can reach isolated areas without relying on ground road/rail infrastructure to drop relief materials.
- C
Air travel generates zero carbon emissions during emergency operations.
- D
Airplanes can land on any rough water surface without specialized runways.
Explanation
Aircraft and helicopters can reach inaccessible disaster-hit areas, deliver relief supplies, and evacuate affected people even when roads and railways are damaged
With reference to Roadways, consider the following statements:
1. Roadways are the most suitable mode of transport for short distances.
2. Metalled roads (pucca) are made of mud and straw, making them unusable during monsoon rains.
3. Flyovers are roads built over raised structures.
Which of the statements given above are correct?
- A
1 and 2 Only
- B
1 and 3 Only
- C
2 and 3 Only
- D
1,2, and 3
Explanation
Statements 1 and 3 are correct. Roadways are the most suitable mode of transport for short distances, and flyovers are elevated roads built over raised structures. Statement 2 is incorrect because metalled (pucca) roads are made of tar, asphalt, or concrete, making them usable in all seasons.
Consider the following statements regarding Earth's atmosphere:
It contains a suitable balance of oxygen and other gases needed to support life.
It shields Earth's surface from harmful radiation coming from space.
Which of the statements given above is/are correct?
- A
1 only
- B
2 only
- C
1 and 2 both
- D
Neither 1 nor 2
Explanation
Both statements are correct, as Earth's atmosphere contains a suitable balance of gases needed for life while also shielding the surface from harmful space radiation. Option A is incorrect as it wrongly excludes the correct second statement. Option B is incorrect as it wrongly excludes the correct first statement. Option D is incorrect since both statements accurately describe Earth's atmosphere.
What is the overarching theme connecting Settlement, Transport, and Communication in human geography?
- A
They represent isolated human activities with no relation to physical geography.
- B
They are human environmental adaptations that enable societies to organize space, move goods, and share information efficiently.
- C
Settlements disappear as transportation and communication technology improve.
- D
Physical geography completely prevents human communication across oceans.
Explanation
The chapter highlights that settlements, transport, and communication are interconnected human adaptations that help societies organize space, facilitate movement of people and goods, and exchange information efficiently, supporting development and global connectivity
Why are Millets (Jowar, Bajra, Ragi) termed hardy crops in agronomy?
- A
They require continuous flooding and greenhouse heaters to germinate.
- B
They can grow on less fertile, sandy soils with low rainfall and high temperatures.
- C
They can only be grown inside deep underground caves.
- D
They require heavy application of expensive synthetic pesticides to survive.
Explanation
Millets are drought-resistant coarse grains that thrive in marginal, less fertile soils under low rainfall conditions.
Consider the following statements regarding Mediterranean vegetation:
1. It is mostly found along the eastern margins of continents in tropical latitudes.
2. Trees adapt to dry summers with thick barks and wax-coated leaves that reduce
transpiration.
3. It is renowned for extensive citrus fruit cultivation such as oranges, figs, and grapes.
Which of the statements given above are correct?
- A
1 and 2 only
- B
2 and 3 only
- C
1 and 3 only
- D
1, 2, and 3
Explanation
Statements 2 and 3 are correct. Statement 1 is incorrect because Mediterranean
vegetation is characteristically found along the western and south-western margins of
continents in mid-latitudes, not eastern margins.
Consider the following statements regarding Jupiter:
It is the largest planet in the entire solar system.
It could fit more than a thousand Earths inside it.
Which of the statements given above is/are correct?
- A
1 only
- B
2 only
- C
Neither 1 nor 2
- D
1 and 2 both
Explanation
Both statements are correct, as Jupiter is the largest planet in the solar system and is massive enough that more than a thousand Earths could fit inside it. Option A is incorrect as it wrongly excludes the correct second statement. Option B is incorrect as it wrongly excludes the correct first statement. Option C is incorrect since both statements accurately describe Jupiter's immense size.
What primary factor has contributed most to transforming the modern world into a "Global Village"?
- A
The complete elimination of physical borders between nations.
- B
Rapid advancements in transport speed and digital communication networks.
- C
The replacement of urban cities with rural farming villages globally.
- D
The decline of maritime international trade.
Explanation
The concept of a Global Village has become possible because of fast transportation and instant digital communication, allowing people, goods, and information to move quickly across the world
What is the primary driving force behind the daily formation of sea waves on the
ocean surface?
- A
Gravitational pull of the Moon
- B
Winds blowing across the ocean surface
- C
Undersea earthquake activity
- D
Evaporation of water by solar heat
Explanation
Friction between wind and the water surface creates regular ocean waves. The
stronger the wind, the greater the wave energy. Tides (Option A) are driven by gravity, while
tsunamis (Option C) are caused by tectonic forces.
Consider the following statements regarding Rainwater Harvesting:
1. It is a method used to collect and store rainwater to recharge groundwater aquifers
and local storage.
2. Concrete paving in urban cities enhances natural rainwater percolation into the
ground.
Which of the statements given above is/are correct?
- A
1 Only
- B
2 Only
- C
Both 1 and 2
- D
Neither 1 nor 2
Explanation
Statement 1 is correct. Statement 2 is incorrect because paving land with concrete
prevents rainwater from seeping into the soil, reducing natural groundwater recharge and
increasing surface runoff in cities.
