Northern Hemisphere
sun
True or False – Earth is closer to the sun in summer.
False
It’s the tilt, not distance, that causes seasons.
Why do direct rays from the Sun make an area warmer than indirect rays? Explain how the angle of sunlight affects temperature.
Direct rays hit Earth at a straight line, so the energy is concentrated in a smaller area and makes it warmer. Indirect rays hit at a slanted angle, so the energy spreads out over a larger area and provides less heat.
Earth’s distance from the sun is often called this, making it “just right” for life.
The Goldilocks Zone
Approximately how long does it take light from the Sun to reach Earth?
About 8 minutes and 20 seconds
