Based on the case study, answer the following questions
During a science exhibition, a group of students used a globe and a torch to understand how sunlight reaches Earth. They noticed that the light was concentrated in a small area near the middle of the globe but spread over a much larger area towards the top and bottom. Their teacher explained that Earth is spherical and therefore sunlight strikes different latitudes at different angles. Near the Equator, the Sun's rays are more direct, whereas towards the poles, the rays become increasingly slanting. As a result, the same amount of solar energy is distributed differently across Earth's surface.
1. Why was the illuminated area smaller near the middle of the globe? -
2. Which region generally receives more concentrated solar energy? -
3. A student concludes that all places on Earth receive sunlight at the same angle. Which observation from the activity disproves this conclusion? -
4. If Earth were flat instead of spherical, what would most likely happen? -
