Moon and Earth By: Jonah Jimenez The Size The Moon’s size is 3476 kL! That’s really big! The Earth’s size is 5.9736x1024kg! That is a huge number! Landforms and Craters There is a crater on the moon called the Ptolemaeus crater. Types of landforms are valleys, mountains, plains etc. Gravity The gravity on the moon is 83.3% less than earths. The gravity on earth is six times more than on the moon. Weather and Atmosphere There is no atmosphere on the moon. The weather on the moon can go from zero degrees celsius to one hundred degrees farenheight! The layers of the earths atmosphere are the troposphere, the ozone layer, and the stratosphere. The weather on earth is constantly changing. We have rain, snow, wind, etc. Water Astronauts discovered 25 chunks of ice on the moon. That’s not a lot of water! Here on earth, water covers about 70% of the surface! Weathering and erosion The moon has some weathering and erosion, but it goes at a much slower rate than the earth. The earth’s weathering and erosion are caused by rain, snow, wind etc. Time to rotate on its axis The moon’s time to rotate on axis is 27.3 days. The earth’s time to rotate on it’s axis is 24 hours (1 day). Time to revolve/orbit once The moon takes 27.3 days to orbit around the earth. The earth takes 365 days to revolve around the sun. Effects on other cycles The gravitational pull on the moon causes the tides we see today. The reason that we have seasons is because of the tilt of the earth. The End End
