Section 3 Motions of the Moon – The changing relative positions of the moon, Earth, and sun cause the phases of the moon, eclipses, and tides
Section 3 Phases of the Moon – Phases – The phase of the moon you seed depends on how much of the sunlit side of the moon faces Earth – What is a new moon?
Section 3 Eclipses (when an object in space comes between the sun and third object, it casts a shadow on the object – When the moon’s shadow hits Earth or Earth’s shadow hits the moon, an eclipse occurs – Two types of eclipses Solar eclipses Lunar eclipses
Section 3 Eclipses – When Do Solar Eclipses Occur A solar eclipse occurs when the moon phases directly between Earth and the sun, blocking sunlight from Earth Solar eclipse – Total Solar Eclipses Umbra – Partial Solar Eclipses Penumbra
Section 3 Eclipses – When Do Lunar Eclipses Occur Lunar eclipses During a lunar eclipse, Earth blocks sunlight from reaching the moon – Total Lunar Eclipses – Partial Lunar Eclipses – During which phase of the moon can lunar eclipses occur?
Section 3 Tides (the rise & fall of ocean water that occurs every 12.5 hrs or so) – Tides are caused mainly by differences in how much the moon’s gravity pulls on different parts of Earth – The Tide Cycle – Spring Tides – Neap Tides
