# Section1: Earth in Space

## How does Earth move in space

Earth moves through space in two ways: rotation and Revolution

Earth rotates on its axis while it revolves around the sun

## Wha causes the cycle of seasons on earth

The cycle of seasons is caused by the amount of sunlight that's hits Earth as it revolves around the sun

# What determines the strength of the force and gravity between two objects.

The strength of the force of gravity between two objects depends on the masses of the two objects and the distance between them. Mass is the amount of matter in an object.

## What two factors combine to keep the moon and earth on the same orbit.

Newton concluded that the two factors inertia and gravity combine to keep the earth on orbit around the sun and moon around earth. A combination of gravity and inertia keeps the moon in orbit around the Earth. If here was no gravity or inertia would cause the moon to travel in a straight line.

## What cause the phase of the moon?

As the moon revolves around earth the relative positions of the moon, earth, and sun change. the changing relative positions of the moon, Earth, and the sun cause the phase of the moon, eclipses, and tides.

## What are solar and lunar eclipses

A solar eclipses occurs when the moon passes directly between the earth and sun, blocking sunlight from Earth. A lunar eclipses Earth blocks sunlight from the moon causing a bloody moon

## What causes the tides

Tides are caused by the difference in how much the moon gravity pulls on Earth. High tides are when the water is either the closets or the farthest from the moon. The low tides are in the middle farthest to the moon.

## What features are found on the moons Surface.

There are many features on the moon surface,one feature is craters. Craters are large pits formed by large meteoroids hitting the moon's surface causing craters.

## What are some characteristics of the moon

• The moon is about one-fourth of the Earths size. The moon has large craters everywhere. There is no air or water on the moon which makes it lifeless.

## How did the moon form

People think that a small plant collided with the Earth. The parts of the small planet form a ring. Eventually gravity push it together to form the moon.
