1. axial tilt, 2. earth revolves, 3.# of daylight hours vs darkness, 4. altitude of sun at different times of the year.
|
why does earth have seasons? ( 4 reasons)
|
|
|
summer solstice(june21)
winter solstice(dec21) fall equinox(sept22) spring equinox(march21) |

|
|
It is the same(rotates at the same speed it revolves) which is why we are always have the same side of the moon facing us.
|
what is strange about the moon's rotation and revolution?

|
what are three differences between a solar and lunar eclipse?
|
|
|
The FISSION Theory, CAPTURE Theory, (CO-ACCRETION Theory), * COLLISION RING Theory: A planetesimal the size of Mars struck the earth, ejecting large volumes of matter. A disk of orbiting material was formed, and this matter eventually condensed to form the Moon in orbit around the Earth.
|
list the three theories of how scientists believe the moon formed, and completely explain the one that scientists believe the most.
|
|
|
1 Moon is at a node, 2 new or full phase position, 3 nearing perigee
|
what are three conditions that make an eclipse probable to happen?
|
|
|
Spring tides occur when the Sun-Earth-Moon are in line—Neap tides occur when they are at a right angle, Spring tides occur at ne and full phase whereas neap tides occur at the quarter phases, Spring tides are the highest highs and lowest lows compared to neap being not very high highs and not very low lows, Spring S-E-M work together<>Neap S-E-M cancel each other out----------*they each occur twice a month

|
A synodic month is how long the moon takes to go from new moon to new moon. A sidereal month is how long it takes the moon to orbit earth. How many days does each take?
