Questions Answers For All Chapters – Geography Class 6
Exercises
(A) Where am I?
1. The isotherm 0°C runs in my surroundings.
→ Polar region (North Pole or South Pole)
2. The mean annual temperature is 25°C around me.
→ Tropical region (near the Equator)
3. The mean annual temperature around me is 10°C.
→ Temperate region (mid-latitudes)
(B) Who am I?
1. I connect places of equal temperature.
→ Isotherm
2. I am useful for measuring the correct temperature.
→ Thermometer
3. I get heated due to the land or water near me.
→ Air
4. Land and water get heated due to me.
→ Sunrays
(C) Answer the following:
1. Explain with a diagram, the effect of the spherical shape of the Earth on the temperature at different latitudes.
- The Earth is round, so sunrays do not fall equally everywhere.
- Near the Equator, sunrays are direct and strong, making it hot.
- Near the poles, sunrays are slanting, covering a larger area, making it cold.
2. What is the relation between the latitudinal extent and temperature of a region?
- As we move away from the Equator towards the poles, the temperature decreases.
- Places near the Equator are hotter, while places near the poles are colder.
3. What makes the isotherms run zigzag over continental areas?
- Land heats up and cools down faster than water, causing uneven temperatures.
- This difference makes isotherms (temperature lines) bend or zigzag over land areas.
