Moon Facts:

1. The moon takes about 27.3 days to orbit the Earth.                                                       2. The Moon is about 250,000 miles away from Earth.                                                       3.On average the Moon moves at 2,288 miles per hour around Earth.

Section 1: Earth in Space

How does earth move in space?

Earth moves through space in two major ways: rotation and revolution. The imaginary line that goes through the center of Earth and the North and South Poles is Earth's Axis. When the Earth spins on its axis, it's called a rotation. Earth's rotation causes day and night and it takes Earth about 24 hours to make a full rotation.

What causes the cycle of seasons on Earth?

Earth has seasons because its axis is tilted as it revolves around the sun. If Earth's axis were straight up and down similar to its orbit, temperatures would remain fairly the same year-round. The Earth's seasons are not caused by the changes in Earth's distance from the sun.

Section 2: Gravity and Motion

What determines the strength of the force of gravity between two objects?

The strength of the force of gravity between two objects depends on two factors: the masses of the objects and the distance between them. Gravity attracts all objects toward one another. If mass increases, force also increases. If distance increases, force decreases.

What two factors combine to keep the moon and earth in orbit?

Newton concluded that two factors, inertia and gravity, combine to keep Earth in orbit around the sun and the moon in orbit around Earth. Earth's gravity pulls the moon towards it, preventing the moon from moving in a straight line. If there wasn't any Earth gravity, inertia would cause the moon to move off through space in a straight line. The sun's gravity pulls on Earth and Earth's inertia keeps it moving ahead.

Section 3

What causes the phases of the moon?

The changing relative positions of the moon, Earth, and sun cause the phases of the moon, eclipse, and tides. The different shapes of the moon you see from Earth are called phases. The moon goes through its whole set of phases each time it makes a complete revolution around Earth. Phases are caused by changes in the relative positions of the moon, Earth, and sun.

What are the solar and lunar eclipses?

When the moon's shadows hits Earth or Earth's shadow hits the moon, and eclipse occurs. There are two types of eclipses, solar and lunar eclipses. A solar eclipse occurs when the moon passes directly between Earth and the sun, blocking sunlight from Earth. A lunar eclipse occurs at a full moon when Earth is directly between the moon and the sun.

What causes the tides?

Tides are mainly caused  by differences in how much the moon's gravity pulls on different parts of Earth. The moon's gravity causes high tide on the side closest to the moon. Low tides occur between the two high tides and the force of the moon's gravity pulls Earth toward the moon, leaving the water behind. There are different types of tides: Spring tides and Neap tides.

section 4

What features are found on Earths surface?

Features on Earth's surface include maria, craters, and highlands. Maria are the dark, flat areas on the moon's surface. The craters are large round pits and some of them can be hundreds of kilometers across. Highlands are the light-colored features on the moons surface. The lunar highlands cover much of the moon's surface.

What are some characteristics of the moon?

The moon is dry and airless. Compared to Earth, the moon is small and has large variations in its surface temperature. The moon is 3,476 kilometers in diameter, a little less than the distance across the U.S. The moon's average density is similar to the density of Earth's outer layers. On the moon's surface, the temperatures range from a torrid 130 degrees Celsius in direct sunlight to a frigid -180 degrees Celsius at night. The moon has no liquid water.

How did the moon form?

Scientists theorize that a planet-sized object collided with Earth to form the moon. Material from the object and Earth's outer layers was ejected into orbit around Earth, where it formed a ring. Gravity caused this material to combine to form the moon.
