🌞 Chapter 2: Energy from the Sun (Quick Revision Q&A)
| Question | Answer |
|---|---|
| What is Insolation? | The solar radiation (energy) received on the surface of the Earth. |
| Why is the Equator hotter than the Poles? | Due to the Earth's curvature, the Sun's rays fall vertically (direct) at the Equator, concentrating heat, but fall slanting at the Poles, spreading heat over a larger area. |
| How does the atmosphere get heated? | The Sun's rays first heat the Earth's surface. The heated surface then radiates heat back, which warms the air (atmosphere) around it. |
| What is 'Heat Balance'? | The balance between the solar energy the Earth receives and the solar energy it radiates back, which maintains a stable global temperature. |
| Why is Solar Energy better than Thermal Power? | Solar energy is renewable and non-polluting (no \text{CO}_2 emissions), unlike thermal power (coal), which is non-renewable and causes global warming. |
🌎 Chapter 3: Earth Movements and Seasons (Quick Revision Q&A)
| Concept | Rotation | Revolution |
|---|---|---|
| Definition | Earth spinning on its tilted axis. | Earth orbiting the Sun in an elliptical path. |
| Time Taken | 24 hours (1 Earth Day). | 365 \frac{1}{4} days (1 Year). |
| Effect | Causes Day and Night. | Causes Seasons and variations in the length of day/night. |
| Question | Key Date & Definition | Result |
|---|---|---|
| What is a Solstice? | June 21 (Summer Solstice in NH) / December 22 (Winter Solstice in NH). The Sun's rays are direct on the Tropic of Cancer/Capricorn. | Unequal day/night length; marks the start of summer/winter. |
| What is an Equinox? | March 21 (Spring) / September 23 (Autumn). The Sun's rays fall directly on the Equator. | Equal day and night length all over the world. |
| Why are seasons possible? | Because the Earth's axis is tilted at \mathbf{23\frac{1}{2}\text{°}} and the tilt remains fixed while the Earth revolves around the Sun. | |
| What is the 'Circle of Illumination'? | The imaginary line that separates the parts of the globe experiencing day from those experiencing night. | |
