Imp Questions For All Chapters – Geography Class 6
Short Questions
1. What is temperature?
Answer : Temperature is the measure of heat in the air at a place.
2. What is the main source of heat on Earth?
Answer : The Sun is the main source of heat on Earth.
3. Why is the Equator hotter than the poles?
Answer : The Equator gets direct sunrays, while the poles get slanting sunrays.
4. What are the three temperature zones of Earth?
Answer : Torrid Zone (hot), Temperate Zone (moderate), and Frigid Zone (cold).
5. How does altitude affect temperature?
Answer : Higher places (mountains) are colder than lower areas (plains).
6. Why is Mumbai’s climate moderate?
Answer : Mumbai is near the sea, so it has less temperature change.
7. What is an isotherm?
Answer : An isotherm is a line on a map connecting places with the same temperature.
8. What is used to measure temperature?
Answer : A thermometer measures temperature in °C or °F.
9. What is the effect of warm ocean currents?
Answer : Warm currents make the climate warmer in nearby coastal areas.
10. How does land and water heat differently?
Answer : Land heats up and cools down quickly, but water heats up and cools down slowly.
11. What are greenhouse gases?
Answer : Gases like carbon dioxide and methane trap heat, causing global warming.
12. What is global warming?
Answer : Global warming is the rise in Earth’s temperature due to pollution and greenhouse gases.
Long Questions
1. Why do sunrays fall differently on different parts of the Earth?
Answer : The Earth is round, so sunrays fall directly near the Equator and slanting near the poles, affecting temperature.
2. How does distance from the sea affect temperature?
Answer : Coastal areas have a moderate climate, while inland areas have extreme temperatures due to land heating faster.
3. Why do mountains have lower temperatures than plains?
Answer : As altitude increases, air pressure and temperature decrease, making mountains colder than lowlands.
4. What is the difference between Torrid, Temperate, and Frigid Zones?
Answer : Torrid Zone is hot, Temperate Zone has a moderate climate, and Frigid Zone is cold due to slanting sunrays.
5. How do warm and cold ocean currents affect climate?
Answer : Warm currents make coastal areas hotter, while cold currents make them colder, affecting local temperatures.
6. How does the greenhouse effect cause global warming?
Answer : Greenhouse gases trap heat in the atmosphere, causing Earth’s temperature to rise and leading to climate changes.
7. What is the difference between isotherms over land and water?
Answer : Isotherms are zigzag over land due to temperature changes but straight over oceans because water temperature changes slowly.
8. Why does Nagpur have an extreme climate, while Mumbai has a moderate climate?
Answer : Nagpur is far from the sea, so it has hot summers and cold winters, while Mumbai’s coastal location keeps the temperature stable.
