The Moon by Sandra Sakauye

Phases of the moon

2014-05-08 15:36:33 UTC

The phase of the moon you see depends on how much of the sunlight side of the moon faces the earth

The moonlight

2014-05-08 15:40:42 UTC

The light we see when the moon is out is actually the sun reflecting on the moon!

Eclipses

2014-05-08 15:43:04 UTC

An eclipse happens when the moons shadow

hits Earth or Earth's shadow hits the moon. There

are two types of eclipses, lunar and solar.

2014-05-08 15:44:13 UTC

Phases are the different shapes of the moon that we see from Earth!

2014-05-08 15:45:15 UTC

What are phases caused by?

2014-05-08 15:46:14 UTC

Phases are caused by changes in the relative positions of the moon, Earth, and the sun. Because the sun lights the moon, half the moon is almost always in sunlight. Since the moon revolves around Earth, we see the moon from different angles.

How tides are caused

sandra_sak — 2014-05-08 15:46:28 UTC

Tides are caused by differences in the moons gravity pull on different parts of the Earth

High tides

sandra_sak — 2014-05-08 15:48:47 UTC

When the Earth pulls toward the moon the force causes high tides.

2014-05-08 15:49:10 UTC

When do solar Eclipses Occur?

2014-05-08 15:50:21 UTC

When the moon passes directly between the Earth and the sun, blocking sunlight from the Earth.

2014-05-08 15:50:44 UTC

Low tides

sandra_sak — 2014-05-08 15:51:28 UTC

Low tides occur between the two high tides

Total Solar Eclipes

2014-05-08 15:52:54 UTC

The umbra is the very darkest part of the solar eclispe.

2014-05-08 15:54:42 UTC

After about 29.5 days after a new moon, a cycle is complete. And a new moon will occur again.

Spring tides

sandra_sak — 2014-05-08 15:54:48 UTC

When a low and a high tide combine forces they produce a spring tide

Neap tides

sandra_sak — 2014-05-08 15:56:26 UTC

When the sun pulls the moon at a right angle , it produces a neap tide. Neap tides make tides that have high and low tides at different times

The Moon's Surface

2014-05-08 15:56:43 UTC

Features on the moon's surface include maria, craters, and highlands.

2014-05-08 15:58:31 UTC

Maria

2014-05-08 15:59:48 UTC

Dark, flat areas on the moon.

Characteristics of the moon

sandra_sak — 2014-05-08 16:03:55 UTC

The moon is the closest neighbor to Earth

Craters

2014-05-08 16:05:46 UTC

Large round pits. Some craters can be hundreds of kilometers across. Craters were caused by the impacts of meteoroids, chunks of rock or dust from space.

Size and Density

sandra_sak — 2014-05-08 16:06:11 UTC

The moon is 3,476 kilometers in diameter. The moon has one-eightieth as much mass as Earth

Temperature and Atomosphere

sandra_sak — 2014-05-08 16:08:39 UTC

The temperature of the moon is 130 Celsius. Temperature on the moon varies because it has no atomosphere. Gravity is weak on the moon, so gas easily can get into space. The moon has no air and it is dry.

Highlands

2014-05-08 16:09:31 UTC

Some of the light-colored features seen on the moon's surface. The peaks of lunar highlands and the rims of the craters cast dark shadows, which can be seen.

Water

sandra_sak — 2014-05-08 16:12:02 UTC

There is no water in space. The temperature is low there, so if there was water it would freeze and stay there

Fun Fact

2014-05-09 15:37:29 UTC

Since our moon does not have an atmosphere- nothing can stop even the smallest meteoroids from striking its surface!

Tides

2014-05-12 15:52:33 UTC

Tides are the periodic rise and fall of the water in the ocean and its produced by the attraction of the moon and sun.

Earths Surface

sandra_sak — 2014-05-14 04:32:06 UTC

sandra_sak — 2014-05-14 04:36:57 UTC

How the moon was created

sandra_sak — 2014-05-14 04:43:31 UTC

The theory of the moons origin that seemed most possible is the collision-ring theory

Theory

sandra_sak — 2014-05-14 04:45:10 UTC

Scientists theorize a planet-sized object collided with Earth to form the moon

sandra_sak — 2014-05-14 04:50:53 UTC

During and After the collision

sandra_sak — 2014-05-14 04:51:57 UTC

Material from the object that collided with Earth and the Earths outer layers were ejected into orbit around Earth, and it formed a ring. Gravity caused the material of the ring to form the moon.
