  1. SCIENCE 8 3-1 CIA REVIEW

  2. We are learning to: describe how objects in the solar system are in regular and predictable motions that explain days, years, and seasons. We are looking for: description of: • Days- Earth rotates on its axis every 24 hours • Years-Earth revolves around the sun 365.25 days • Seasons-Earth revolves around the sun as the Earth is tilted on its axis

  3. Why do we have night and day? • Earth’s rotation • Earth’s revolution • Tilt of the Earth on its axis • I need Help!

  4. What causes Earth to experience different seasons? • It rotates on its axis while it revolves around the sun • It revolves on its axis while it rotates around the sun • It is tilted while it rotates around the sun. • It is tilted while it revolves around the sun. • I need help!

  5. If the Earth’s Revolution was slower, we would experience • Longer days • Shorter days • Longer years • Shorter years • I need help!

  6. Of the following, which does not affect seasons? • Earth is tilted 23.5 degrees • The Earth revolves around the sun • The Earth’s distance from the sun • I need help!

  7. We are learning to: describe how objects in the solar system are in regular and predictable motions that explain phases (moon cycles), eclipses, tides We are looking for: a description of -Phases-moon revolves around the Earth approximately once a month-Eclipse-are random predictable; one object moves in front of another object in relation to the position of the sun -Tides-high tide occurs approximately twice a day due to the gravitational pull of the moon

  8. Which phase occurs when the moon is in between the Earth and the sun? • Full moon • New moon • 1st Quarter moon • 3rd quarter moon

  9. What causes us to see different phases of the moon? • Light refracts off of the surface of the moon. • The moon rotates around the Earth. • We see different perspectives of the moon. • I need help!

  10. What is the main cause of tides? • The gravitational pull of the moon • The gravitational pull of the sun • The gravitational pull of the Earth • I need help!

  11. If the sun, moon, and Earth are perfectly aligned (as pictured), what event will occur on Earth? • Neap Tide • Solar Eclipse • Lunar Eclipse • Seasonal Change

  12. When studying a solar eclipse, which would be a proper method of viewing the sun? • Wear sunglasses • Use a telescope • Use a magnifying glass • Use filters that are specifically designed to view eclipses • I need help!

  13. We are learning to: explain that gravitational force determines motions in the solar system and keeps the planets in orbit around the sun.We are looking for: explanation that*All objects in the solar system have gravity.*Sun has the greatest mass, thus has the greatest gravitational pull within our solar system.*Since planets have inertia, they do not get pulled into the sun. *Gravity keeps the planets in orbit.

  14. What is an object’s resistance to a change in motion? • Gravity • Inertia • Mass • Friction • I need help!

  15. Predict what would happen if Earth stopped its forward motion around the sun? • It will fly off into space. • It will hit the nearest planet. • It will get pulled into the sun. • It will continue to revolve.

  16. What keeps planets revolving around the sun? • The sun’s gravitational pull. • The planet’s mass. • The planet’s magnetic field. • The Sun’s inertia. • I need help!
