Moon, Earth, and Sun
By Matthew Fantauzzo
Section #1 Earth in space
#1 How does Earth move in space?
Earth moves through space in two major ways: rotation and revolution
Earth's axis is the imaginary line that passes through the North and South Poles. The axis causes Earth to spin.
The Earth revolves around the Sun in an orbit.
#2 What causes the cycle of seasons on Earth?
Earth has seasons because its axis is tilted as it revolves around the sun.
Section #2 Gravity and motion
#1 What determines the strength between two objects?
The strength of the force of gravity between two objects depends on their masses and the distance between them.
#2 What two factors combine to keep the moon and the Earth in orbit?
Inertia and gravity are the two factors that combine to keep the moon and Earth in Orbit.
The tendency of an object to resist a change in motion.
Section #3 Phases, Eclipses, and tides
#1 What causes the moon phases?
The changing relative positions of the moon, Earth, and sun cause the phases of the moon.
The phase of the moon you see depends on how much of the sunlit side of the moon faces Earth.

#2 What are solar and lunar eclipses?
The changing relative positions of the moon, Earth, and sun cause the solar and lunar eclipses.
A solar eclipse occurs when the moon passes directly between the Earth and the sun, blocking sunlight from Earth.
During a lunar eclipse, Earth blocks sunlight from reaching the moon.
#3 What causes the tides?
The changing relative positions of the moon, Earth, and sun cause the tides.
Tides are caused mainly by differences in how much the moon's gravity pulls on the different parts of the Earth.
Section #4 Earth's moon
#1 What features are found on the moon?
Features on the moon include maria, craters, and highlands.
Maria-The dark flat areas on the moon.
Craters- Large round pits on the moon.
Highlands- The light colored features on the moon's surface.
#2 What are some characteristics of the moon?
The moon is dry and airless. Compared to the 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 United States.
On the moon's surface, temperatures range from a torrid 130°C in direct sunlight to a frigid -180°C at night.
The moon has no liquid water. But there is some evidence of large patches of ice near the moon's poles.
#3 How did the moon form?
Scientists theorize that a planet-sized object collided with Earth to form the moon.
