Earth, Moon, and Sun interactions

1. Earth, Moon, and Sun interactions

2. Answers To Look For • Why is it warmer near the equator? • Why are there tides in the ocean?’ • What are solar eclipses and lunar eclipses? • Why do the moon and earth stay together? • What causes the earth to be warm?

3. The Equator • Earth and Sun interaction • Earth tilts on its axis • Equator is always pointed at the sun • The suns heat hits the equator first

4. Tides • Relation ship between moon and Earth • The moons gravity pulls tides towards it • Earths spin also helps with tides • Many animals depend on tides to live

5. Eclipses • Eclipses occur when planets are align • Sun-earth-moon • Or Earth-moon-sun • Occur periodically • Only occur for a few moments

6. Why is the Earth Warm • Sun and Earth interactions • Sun creates nuclear heat • Sent in waves at Earth • Seasons are determined by tilt of earth and position in relativity to earth

7. The Dark Side • The side of the moon that doesn’t see the sun • Its much colder than the rest of the moon • Makes it so that the moon has phases • Earth blocks view of the sun from the moon

8. Gravity • Occurs between all thing • Earths gravity pulls the moon • Suns gravity pulls all planets • Keeps us in orbit • Pulls us to the ground

9. Moon phases • There are 8 moon phases • Created by earths shadow • Phase 1 - New Moon • Phase 2 - Waxing Crescent. • Phase 3 - First Quarter • Phase 4 - Waxing Gibbous • Phase 5 - Full Moon • Phase 6 - Waning Gibbous • Phase 7 - Last Quarter • Phase 8 - Waning Crescent

10. Solar Flares • Large bursts of energy from the sun • 6 x 10 to the 25th power joules • Equivalent to 160,000,000,000 megatons of TNT • Very powerful • 160,000,000,000 megatons of TNT
