Earth, Moon, and Sun.
By: Jordan Crider

          Section 1: Earth in Space

Q: How does Earth move in space?

A: Earth moves through space in two major ways: rotation and revolution. Rotation- The spinning motion of a planet on its axis. Revolution- The movement of an object around another object.

Q: What causes the cycle of seasons on Earth?

A:Earth has seasons because its axis is tilted as it revolves around the sun.

    Section 2: Gravity and Motion

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

A: The strength of the force of gravity between two objects depends on two factors: the masses of the objects and the distance between them.

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

A: Newton concluded that two factors, inertia and gravity, combine to keep Earth in orbit around the sun and the moon in orbit around Earth.

      Section 3: Phases, Eclipses, and                                   Tides.

Q: What causes the phases of the moon?

A: The changing relative positions of the moon, Earth, and sun cause the phases of the moon, eclipses, and tides.

Q: What are solar and lunar eclipses .

A: A solar eclipse occurs when the moon passes directly between Earth and the sun, blocking sunlight from Earth. During a lunar eclipse, Earth blocks sunlight from reaching the moon.

Q: What causes the tides to occur

A: Tides are caused mainly by difference in ho much the moon's gravity pulls on different parts of Earth.

          Section 4: Earth's Moon

Q: What features are found on the moon's surface?

A: Features on the moon's surface include maria, craters, and highlands.

Q: What are some characteristics of the moon?

A: The moon is dry and airless. Compared to Earth, the moon is small and has large variations in its surface temperature.

Q: How did the moon from?

A: Scientists theorize that a planet-sized object collided with Earth to from the moon.
