  • What causes eclipses? Why are solar eclipses less common to see?
    When moon's shadow hits earth, or earths shadow hits the moon. Moon has smaller shaddow.

    The tide with the smallest difference between high and low tide.
  • What happens every 24 hours?
    Earth Rotates once on its Axis
  • What factors keep the moon in orbit around the earth? Earth around Sun?
    Gravity and Inertia
  • What season is it here when the south end of Earth's axis is tiled toward the sun?
    Winter in the Northern Hemisphere
  • This can only occur at FULL moon
    Lunar Eclipse
  • When we weigh ourselves what does the number represent?
    The force of gravity on an object (us)
  • Describe the Vernal Equinox. (Sun Position, Approximate Dates)
    March 21st, First day of spring, Sun is overhead at noon
  • What causes a Spring Tide?
    when the sun and moon are at right angles to Earth

    Distance and Mass
  • What is the positions of the Earth Sun and Moon in a solar eclipse?
    Sun, Moon, Earth
  • What CAUSES an Equinox?
    Neither hemisphere is tilted toward the sun. 12 hours of day and night

  • Describe the Collision Ring Theory
    A planet sized object collided with Earth. Part of Earth's crust was cast into space and was caught in Earth's orbit. This material formed the moon.
  • The two days of the year when the sun is either 23.5 degrees north or south?
    solstices
  • Why couldn't Galileo study the entire moon's surface? What methods can we use today to do so?
