Earth, Moon, and Sun.

By Andrew Batista

Section 1. Earth in  Space

How does Earth Move in Space?

Earth moves in two major ways: Rotation and revolution.

Rotation is the spinning of earth on its axis. This creates night and day. This takes 24 hours to complete.

Revolution is the path earth takes around the sun. An entire revolution is a year, which takes about 365.25 days.

What Causes the cycle of seasons on earth?

The cycle of seasons is caused by earths revolution around the sun. At different times of the year, areas of earth get more or less direct sun rays, depending on where they tilt towards.

Section 2. Gravity and Motion.

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

The strength of gravity depends on 2 factors: the masses of the objects and the distance between them.

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

Two factors keep the earth and moon in orbit: inertia and gravity.

Inertia is the earth and moon moving and resisting gravity, but the gravity still keeps them in orbit and not floating away.

Section 3. Phases, Eclipses, and Tides.

What causes the phases of our moon?

The changing relative positions of the Earth, moon, and sun cause the phases of our moon.

What are Solar and Lunar eclipses?

When the moon's shadow hits earth or Earth's shadow hits the moon, and eclipse occurs.  A lunar eclipse occurs when Earth blocks the sunlight from reaching the moon. A solar eclipse is when the moon passes between the earth and the sun, blocking the sun light from reaching Earth.

What causes the Tides?

Tides are caused mainly by differences in how much the moon's gravity pulls on different parts of Earth.

Section 4. Earth's moon.

What features are found on the moons surface?

The moon has many craters, highlands, and maria. Maria are hardened rivers of lava.

What are some characteristics of the moon?

The moon is dry and airless. The moon is about a fourth the size of earth. The moon also does not have any water, but it does have large patches of ice in craters and near the poles.

How did the moon form?

Scientists think that a smaller planet collided with earth and the parts that were ejected and formed a ring. Gravity eventually pulled it all together and created the moon.

I agree with Briana. The tack had all the information but it was a little boring
