Our Planet Earth!!!
Our Natural Satellite
• Earth’s natural satellites are like the moon. Earth has one natural satellite.
Our Artificial Satellite
• Artificial satellites are like radio stations and TV channels. Earth has more than any other planet.
Gravity
• Gravity is what holds you down on Earth and not just let you float in the air. Gravity depends on the atmosphere.
Oceans
• The ocean almost covers ¾ (75%) of the Earth.
Environment
• Most of the Earth’s land was full of trees and thousands of grasslands, but now there are mostly homes and businesses.
Size
• Earth’s diameter (distance around the Earth) is 12,756.3 km.
Earth’s Past
• Earth was full of dinosaurs and trees. Can you tell me how Earth has changed?
Earth’s Future
• Earth, in time, will be horrible because trash will be all over the place. There might be hover crafts. Can you tell how it will change?
Questions
• How many natural satellites does Earth have? How many unnatural ones? What shape is Earth?
• What lived on Earth before us? How much water covers Earth? Can you tell me what you think will be on Earth after us? What will Earth look like?
