Chapter One: Earth, Moon, and Sun.
By: Ty Yurkovich

Section One
Earth in Space

How does Earth move in space?

Earth moves in space two ways, revolution and rotation.

Earths revolution travels around the sun. A revolution is the movement of one object around another. Earths rotation happens by Earth Spinning around on is axis. Rotation is the spinning motion of a planet on its axis.

What causes the cycle of seasons on Earth?

The Earths axis is tilted meaning that is is not directly up straight. It will stay in this postition throughout its revolution around the sun. When it is warm where you are then your hemishere is getting more direct sunlight than the other hemishere warmin it up more. In the hemisheres when it is summer in one it will be winter in the other.

Section Two
Gravity and the Moon

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

The mass and distance determine the strength of the force o gravity between two objects. Gravity attracts all objects toward each other. If mass increases, force also increases. If distance increases, force decreases.

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

The two factors combined that keep Earth and the moon in orbit are gravity and inertia. Inertia is the tendency of an object to resist change in motion.

Section Three
Phases, Eclipses, and Tides

What causes the phases of the moon?

As the moon makes a revolution around the Earth it reflects light from the sun. Depending on were the moon is compared to the sun and the Earth will be a certain type of moon. If it is behind the Earth then it will be a full moon. If it is in between the Earth and sun the it will be a new moon. If it is to the side of Earth then it will be a half moon.

What are solar and lunar eclipses?

An eclipses occurs when either Earths shadow hits the moon or the moons shadow hits Earth. A solar eclipses occurs when the moon passes directly between Earth and the sun, blocking sunlight from Earth. In a lunar eclipses, Earth blocks sunlight from reaching the moon. During a lunar eclipse the moon will appear to be red, this is called a blood moon.

What causes the tides?

Tides are caused mainly by differences in how much moons gravity pulls on different parts of Earth. In the two places that the  water is closest and farthest from the moon is when it will be high tide, The two that are in the middle of the high tides is called the low tides.

Section Four
Earths Moon

What features are found on the moons surface?

There are craters found on the moons surface. Craters a large round pits formed by meteoroids hitting the moons surface.

What are some characteristics of the moon?

Some characteristics of the moon is that it is dry and airless. On the moons surface the temperature can get up to 130 degrees C during the day and -180 degrees C at night.

How did the moon form?

The moon was theoretically formed by the collision-ring theory. The theory is that a planet-sized object collided with Earth to form the moon.
