Presentation Transcript

  1. Earth Science Review • If you were a meteorologist, what kind of weather would you predict New York, NY to have tomorrow? • Warmer with no precipitation • Colder with precipitation • Warmer with rain showers • Colder with no precipitation

  2. Earth Science Review • If you were a meteorologist, what kind of weather would you predict Denver, CO to have tomorrow? • Warmer with no precipitation • Colder with precipitation • Warmer with precipitation • Colder with no precipitation

  3. Earth Science Review Look at the picture below. What time of day would the shadow of the tree be the shortest? • In the morning • At noon • In the mid-afternoon • In the evening

  4. Earth Science Review Look at the picture below. Based on the shadows, what is the position of the sun? • In the western sky • Directly overhead • In the eastern sky • Behind clouds

  5. How the Moon Affects the Tides

  6. Tides • The Moon’s gravity tugs on the Earth. • It pulls the most on the part of the Earth that is closest to the Sun, which raises the atmosphere, the oceans, and even the rocks (a little) • It pulls the least on the part of Earth that’s farthest, which allows the oceans and atmosphere to be further from the Moon (and higher) • The Sun’s gravity does the same thing, but to a lesser extent

  7. When the moon is new or full, the gravitational forces of the sun and moon are pulling at the same side of the earth. (See the diagram to the left.) This occurrence creates the extra large "spring" tides. When the moon is at first and third quarter, the gravitational forces of the sun and moon are pulling at 90 degrees from each other. (see the diagram to the left.) This occurrence yields little net tides called neap tides.

  8. How Tides Look on the Earth Every twelve hours, you will have two high tides and two low tides.
