The MoonWhat do we already know about the Moon?
Talk With Your Group!How do you think the Moon affects us here on Earth?
The effects of the MoonPhases of the moonEclipsesTides
Talk With Your Group!Why/How do you think Moon phases occur?
Why does the moon have phases?The changing relative positions of the moon, Earth, and sun cause the phases of the moon!
Talk With Your Group!Why do you think eclipses occur?
Why do eclipses occur?Sometimes the Earth, sun, and moon line up so that one object is blocking or shadowing another
Talk With Your Group!Why do you think we have tides?
Why does the Earth have tides?The sun and moon pull on the Earths water causing the tides to rise
Phases of the Moon
TidesPeriodic rise and fall of large bodies of water caused by the gravitational attraction of the moon to the Earth.
High TideOutward bulge of water. Occurs twice per day
Low TideTrough left by the movement of water to the two bulges. Occurs twice per day
Spring TideFull or new moon causes the gravity of sun and moon to combine causing extreme high and low tides
Neap tideMoon is in Quarter phase causing the gravity of the sun and moon to cancel each other. (Sun and moon pull at a right angle)Smaller difference between high and low tides

Tides: Rate Your Learning!Do you think you could explain tides to a friend? If so, then you are a 4!Could you Ace a quiz on tides? You are a 3!Do you want to study a little, then take a quiz? You are a 2!
The Moons Tilted OrbitThe moons orbit is tilted by 5 degrees, so it is infrequent for the sun, moon, and earth to all line up. When these objects do align, eclipses occur.
EclipseWhen the moons shadow hits Earth or Earths shadow hits the moon, an eclipse occurs
Types of EclipsesSolar eclipse solar is Latin for sunOccurs when the moon passes directly between Earth and the sun, blocking sunlight from EarthLunar eclipse- lunar is Latin for moonOccurs when Earth blocks sunlight from reaching the moon
Total Solar EclipseLight from the sun is completely blocked by the moon; within the umbraUmbra- the very darkest part of the moons shadow on EarthPartial Solar EclipsePart of the sun is visible from Earth within the penumbraPenumbra- larger part of the moons shadow on Earth
Total Lunar EclipseWhen the moon is in Earths umbra, a total lunar eclipse occurs.Can be seen anywhere on Earth that the moon is visiblePartial Lunar EclipseOccurs when the moon passes partly into the umbra of Earths shadow; can appear orangeThe edge of the umbra appears blurry, and you can watch it pass across the moon for two or three hours.
Eclipses: Rate Your Learning!Do you think you could explain both Solar & Lunar Eclipses to a friend? If so, then you are a 4!Could you Ace a quiz on Eclipses? You are a 3!Do you want to study a little, then take a quiz? You are a 2!
