Earth, Moon, and Sun

by: Ben Knapik

Earth in Space

How does Earth move in space?

Earth Moves through space by rotation and revolution.

Earth rotates on its axis, which is an imaginary line that passes through Earth's North and South poles.

Earth revolves around the Sun in an ecliptic orbit.

What causes the cycle of seasons on Earth?

The tilt of Earth on its axis causes the seasons.

When one hemisphere is tilted towards the Sun, it is Summer in that hemisphere and Winter in the other.

When neither hemispheres are tilted towards the Sun, one is in Spring and the other is in Fall.

Gravity and Motion

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

The Mass and distance between two objects determines the force of gravity between the objects.

When mass increases, the force of gravity increases.

When mass decreases, the force of gravity decreases.

When distance increases, the force of gravity decreases.

When distance decreases, the force of gravity increases.

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

Inertia and gravity combine to keep the moon and Earth in orbit.

Earth's gravity pulls the moon towards it, but inertia makes the moon want to keep moving forward in space. This effect creates the ecliptic orbit that all planets follow.

Phases, Eclipses, and Tides

What causes the phases of the moon?

Phases are caused by changes in the relative position of the Earth, Moon, and Sun.

The moon has no light of its own, the light you see is reflected from the sun.

Half of the moon is always illuminated by the sun, but that half is not always facing us, making it seem like less than half of the moon is illuminated.

What are solar and lunar eclipses?

Solar Eclipses occur when the moon passes between the Sun and the Earth. The moon completely blocks out the sun and casts the Earth in darkness.

Lunar Eclipses occur when the Earth is directly between the Sun and the Moon, casting the moon in darkness.

What causes the tides?

The moon's gravity pulls Earth towards it leaving the water behind.

The water from the other sides of the Earth flow towards the moon, making the tides across from each other the same.

Earth's Moon

What features are found on the moon's surface?

Maria, Craters, and Highlands, are found on the moon

Maria are dark spots on the moon caused by lava flows 3-4 billion years ago.

Craters are large, round pits caused by the impact of meteoroids.

Highlands are light colored spots on the moon, which are mountains.

What are some characteristics of the moon?

The moon is about 384,000  kilometers away from the earth. It is Earth's Closest neighbor in space. The moon is 3,476 kilometers in diameter and the temperature ranges from 130 degrees Celsius during the day and -180 degrees Celsius at night. There is no liquid water, but there are evidences of ice.

How did the moon form?

Scientist believe that a giant meteorite crashed into the Earth. That mass was eventually thrown off the Earth and held in its orbit, making the moon.

Scientists first got this idea when they found out that many of the materials on the moon are found on Earth.
