📊 Geography
Q. Weather is best defined as:
  • (A) Average atmospheric condition over 30 years
  • (B) Daily state of the atmosphere at a particular place and time
  • (C) Climate of a continent
  • (D) Movement of ocean currents
💬 Discuss
✅ Correct Answer: (B) Daily state of the atmosphere at a particular place and time

Explanation: Weather refers to short-term atmospheric conditions such as temperature, humidity, rainfall and wind.

📊 Geography
Q. The unit commonly used for measuring rainfall is:
  • (A) Millimeter
  • (B) Kilogram
  • (C) Kelvin
  • (D) Pascal
💬 Discuss
✅ Correct Answer: (A) Millimeter

Explanation: Rainfall is measured as the depth of water collected in a rain gauge, expressed in millimeters.

📊 Geography
Q. Wind is caused mainly due to:
  • (A) Earth’s rotation only
  • (B) Unequal heating of Earth’s surface
  • (C) Ocean currents
  • (D) Earthquakes
💬 Discuss
✅ Correct Answer: (B) Unequal heating of Earth’s surface

Explanation: Different heating creates pressure differences; air moves from high to low pressure forming wind.

📊 Geography
Q. Which gas is most responsible for the greenhouse effect?
  • (A) Nitrogen
  • (B) Oxygen
  • (C) Carbon dioxide
  • (D) Argon
💬 Discuss
✅ Correct Answer: (C) Carbon dioxide

Explanation: Carbon dioxide traps heat in the atmosphere and plays a major role in warming and weather patterns.

📊 Geography
Q. A sudden fall in air pressure usually indicates:
  • (A) Clear sky
  • (B) Storm or rain
  • (C) Snowfall always
  • (D) Heat wave
💬 Discuss
✅ Correct Answer: (B) Storm or rain

Explanation: Low pressure systems are associated with rising air, clouds and precipitation.

📊 Geography
Q. Relative humidity refers to:
  • (A) Amount of oxygen in air
  • (B) Water vapor present compared to maximum possible at that temperature
  • (C) Total rainfall in a year
  • (D) Moisture in soil
💬 Discuss
✅ Correct Answer: (B) Water vapor present compared to maximum possible at that temperature

Explanation: Relative humidity expresses how saturated the air is with water vapor.

📊 Geography
Q. Which cloud type is associated with thunderstorms?
  • (A) Cirrus
  • (B) Stratus
  • (C) Cumulonimbus
  • (D) Nimbus
💬 Discuss
✅ Correct Answer: (C) Cumulonimbus

Explanation: Cumulonimbus clouds are tall, dense clouds producing lightning, thunder and heavy rain.

📊 Geography
Q. The line joining places of equal atmospheric pressure on a map is called:
  • (A) Isotherm
  • (B) Isohyet
  • (C) Isobar
  • (D) Contour
💬 Discuss
✅ Correct Answer: (C) Isobar

Explanation: Isobars help meteorologists identify pressure systems and predict weather.

📊 Geography
Q. Which instrument measures wind speed?
  • (A) Anemometer
  • (B) Barograph
  • (C) Hydrometer
  • (D) Altimeter
💬 Discuss
✅ Correct Answer: (A) Anemometer

Explanation: An anemometer records the speed of wind, important for forecasting storms.

📊 Geography
Q. Hail is formed when:
  • (A) Rain freezes on ground
  • (B) Strong updrafts carry water droplets upward and freeze
  • (C) Snow melts in air
  • (D) Fog condenses
💬 Discuss
✅ Correct Answer: (B) Strong updrafts carry water droplets upward and freeze

Explanation: In thunderclouds, rising air currents freeze droplets repeatedly forming hailstones.
