Physics Chemistry & Biology Test 4
Hot or Warm Air always
  • Both a and b
  • None of the above
Explanation:

Warm air rises due to lower density, while cooler air sinks, creating convection currents. This process influences weather patterns, forming clouds and causing wind, crucial for Earth's climate dynamics.

On cooling air, Air
  • Expands
  • Contracts
  • Both a and b
  • None of the above
Explanation:

When air cools, its molecules slow down and move closer together, causing the air to contract and become denser.

Air exerts ?
  • Humidity
  • Pressure
  • Both a and b
  • None of the above
Explanation:

Air has weight, and as it presses down on the Earth's surface, it exerts atmospheric pressure. This pressure varies with altitude, temperature, and humidity.

Thunderstorms develops in ?
  • Clod, Humid Tropical areas
  • Hot, Humid Tropical areas
  • Clod, Humid Tropical areas
  • All the above
Explanation:

Thunderstorms typically form in hot, humid tropical regions where the warm air rises, carrying moisture upward. This moisture condenses at higher altitudes, creating clouds and potentially leading to thunderstorms.

During lighting, which of the following is safest place ?
  • Open Garages
  • Car or Bus
  • Storage Sheds
  • All the above
Explanation:

During lightning, the safest place is inside a car or bus.

These vehicles provide a protective metal shell that can redirect lightning strikes around the occupants. Open garages and storage sheds do not offer the same level of protection.

Which of the following, tropical rain forest are found ?
  • India
  • Malaysia
  • Uganda
  • All the above
Explanation:

Tropical rainforests are found in various countries, including India (particularly in the northeastern region), Malaysia, and Uganda. These regions have the warm, humid conditions that support rich biodiversity typical of tropical rainforests.

Tropical rain forests are found in ?
  • Western Ghats
  • Eastern Ghats
  • Assam
    • Explanation:

    Tropical rainforests are found in both the Western Ghats and Assam in India. The Western Ghats are known for their rich biodiversity and dense forests, while Assam, located in northeastern India, also has significant tropical rainforest areas, particularly in regions like Kaziranga National Park.
