The Earth, Moon, and Sun

By: Jason Hildebran

Earth in Space

How does the Earth move in space?

Earth moves in two ways in space. The first is rotational. The Earth rotates around its axis and each rotation makes up one and slightly more than one day. The second way of moving is revolution. The Earth revolves around the sun. One revolution equals one year and a fourth of a day.

What causes the cycle of seasons on Earth?

The tilt of Earths axis is responsible for the seasons. As Earth revolves around the sun, light hits Earth with more or less direct light depending on where you are on Earth. Equinoxes are when the day is the same amount of time as night. The solstices are when the day and night are the farthest time apart. Summer has the longest day and winter has the longest night.

Gravity and Motion

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

Their are two variables in gravity between two objects. They are the mass of both the objects and the distance between both the objects. The greater the mass between the two objects means that their is more pull between the them. When the objects are closer together the force of gravity is stronger between each other.

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

The two factors that keep the Earth and the moon in orbit is inertia and gravity. Inertia is the tenancy of an object to resist a change in motion. This means that the Earth and the moon stay in motion and use gravity to stay in the same pattern in space.

Phases, Eclipses, and Tides

What causes the phases of the moon?

What are solar and lunar eclipses?

The phase of the moon that is shown depends of how much of the sunlit part of the moon you see. The sun causes the phases and we see the reflected light off of the moon.

They are when the shadow of the moon hits the Earth or the shadow of the Earth hits the moon. When a solar eclipse occurs, the moon casts a shadow on the Earth. A lunar eclipse happens when the Earth is in front of the moon so it casts a shadow on the moon. Lunar eclipses are much more common and last longer because the Earth is larger than the sun.

What causes the tides?

The Earth pulls the moon towards it but the moon has gravity which pulls the Earth toward it. The ocean's tides are evidence of that. The moon pulls on the water which cause tides.

This is where I did my research and made this tackk.

Earth's Moon

What features are found on the moon's surface?

The moon's surface is made up of maria, craters, and highlands. Maria means seas in Latin but maria is actually are dark, flat areas on the moon. Craters are large indents on the moon in the shape of a crater. They are very large across being hundreds of kilometers across. They are caused by meteoroids. Highlands are light spaces on the moon. They cover most of the moon and are mountains are hills.

What are some characteristics of the moon?

The moon is airless and very dry. The surface of the moon has large variations in temperature. The moon is very small compared to Earth. It's diameter is about the same as the distance across the United States. The moon's temperature ranges from 130°C to -180°C. This happens because it has no atmosphere. There is no liquid water on the moon but there is ice near its poles.

How did the moon form?

Their are many theories about how it formed but the most logical is called the collision-ring theory. 4.5 billion years ago the solar system was full of rocky debris. One of the rocks collided with the Earth and became the moon.
