2 Size The Moon is ¼ the size of earth The Moon is 2,000 miles in diameterThe Earth is four times the size of the Moon
3 The Moon’s Landforms/Craters Craters were created by meteors hitting the moon’s surface. Scientists believe craters on the moon were formed around 3.5 to 4.5 billion years ago. Other landforms on the moon are mountains, valleys and lava plains.
4 Earth’s landforms and craters A meteorite crater, or an impact crater forms when a meteor greater than 3 feet in diameter hits the surface. The earth’s landforms include canyons, caves, mountains, plateaus, plains and valleys..
5 GravityIf you weigh 60 pounds on earth you’d weigh 1/6 of your heaviness on the moon so technically you’d weigh 10 pounds. Gravity on earth is 6 times stronger than it is on the moon. Gravity was discovered nearly 3 centuries ago by Sir Isaac Newton. The moons gravitational force is only 17% of the earth’s gravity.
6 AtmosphereThe moon has no atmosphere that’s why it has so many craters. The earth does have an atmosphere that is why there are very few craters on our planet. When an asteroid comes towards earth it is burned up by our atmosphere. The gases in the atmosphere that help retain gases are called greenhouse gases.
7 Weathering and Erosion In the darkest regions of deep space temperatures drop to negative 450 degrees Fahrenheit. Closer to the sun temperatures reach thousands of degrees.
8 WaterIt has been proven that there is about 25 gallons of water on the moon. That’s not very much! The earth is 72% water.
9 Time to rotate on it’s axis It takes the moon about 27 days to rotate once on it’s axis. It takes the earth 24 hours to rotate once, this creates 1 day.
10 Time to revolve/orbit once It takes the moon 29 days to orbit once around the it earth once. It takes the earth 365 and ¼ of a day to orbit around the sun.
11 TidesTides are caused by slight variations in gravitational attraction between then Earth and the moon. There is low tide and high tide.
12 SeasonsAs you most likely know there are four seasons Winter, Summer, Fall and Spring.The seasons are caused by the tilt of the Earth’s rotational axis or toward the sun as it travels through it’s year-long path around the sun.
