The Earth is a sphere that is made out of dirt and water. While the core is made out ofsilicon, iron, magnesium, aluminum, oxygen and other minerals. The reason Earth has a magnetic field is because the iron core. The Earth has 1 moon and 12 people have been on it. A lot of people study Earth their is even jobs and schools for people who are interested for it.The Earth is 93 million miles away from the Sun
The Earth is very important to human life because it is the only planet that has an atmosphere, water,and oxygen.Earth is the only planet that can sustain life ,so we can't just treat badly. The Earth is fragile,and the surface is split into which float on a rocky mantle.The Earth has fewer craters that the Moon,Venus,and Mars because of erosion.
The Earth is in the Milky Way Galaxy,and is the third planet in then solar system. Early astronomers thought the Earth was the center of the universe.The Solar System is located in the middle of the galactic disk ,but the center of the Milky Way Galaxy is 27,000.In the Milky Way the Earth is located in a place called the Orion's Arm.The Milky Way is in the Virgo Cluster which is a bunch of galaxies held up by gravity.
The Earth was made 4.54 billion years ago, and the moon is 4.53 billion years ago. Copernicus is the person who discovered we were on the Earth in the first place in 1543 .3.5 billion years ago the first sign of life is here, also 3 billion years ao plate tectonics came into place.300 million years ago the Earth was a supercontinent.It was a greek philosopher who said and proved that the world was round and his name is Pythagoras.
People should know about their home planet. If people don't know about their own planet they could do something bad to it. We should care for the Earth because we won't get another one. If we keep on treating the Earth badly we could destroy the atmosphere ,and harmful UV rays could get in and destroy us.Earth has limited resources and takes awhile for them to regenerate back.If we don't polluting the air it could mess up the food,water,and air.
I learned that the Earth needs to be treated than what it is right now because it is so old and fragile. We are using up a lot of fossil fuels and they take million of years to come back.I choose this book because of Mr.Brown's science class since we are talking about the earth.I thought the effects on the Earth were very short,but I was wrong some of them were permanent or long side effects.We are now looking for planet that can support life because of the damage we done to it.
