NASA Space Place Explore Earth & Space! Earth’s Atmosphere A jacket for the planet Earth is a great planet to live on because it has a wonderful atmosphere around it. This jacket of gases does a lot for us. It keeps us warm, it gives us oxygen to breathe, and it’s where our weather happens. The atmosphere surrounds our planet like the peel of an orange. But it’s not

In order to understand the importance of citizenship, we first have to look at what the word really means. By definition, citizenship is the position or status of being a citizen of a particular country. However, to many others, it means so much more than that. We as Americans tend to take advantage of the opportunities that have presented themselves since the day we were born into this country. We as Americans have the right to freedom of speech, press, religion, assembly, and to petition the government. We as Americans have the right to vote, to bear arms, and to hold speedy trials. We as Americans have a choice...But the same is not true for the rest of the world. Thousands of people from many different countries do not have the same rights. In fact, some of them don’t even have rights at all. They can’t express their opinions the same way we do. They can’t choose who will run their nation. They are not free. That’s why a lot of them will come to the United States-they want the same opportunities. To those people, citizenship can mean a new life, a new beginning. Being a part of the U.S.A gives them the right to vote, to bear arms, and the ones protected in the first amendment. Though the citizenship process is not an easy one, they work hard for the freedom they deserve. We have been blessed since the day Columbus discovered this land, which in a way, makes us all immigrants. That is why citizenship is so important.
the same everywhere. It has different layers with different qualities.
ONE ATMOSPHERE, MANY LAYERS Earth’s atmosphere has six different layers. They go from the ground all the way to outer space.
We will discuss the first layer and the layer we call home! This is the layer that is closest to the surface of Earth and is called the troposphere. “Tropos” means change. This layer gets its name from the weather that is constantly changing and mixing up the gases in this part of our atmosphere. The troposphere is between 5 and 9 miles (8 and 14 kilometers) thick depending on where you are on Earth. It’s thinnest at the North and South Pole. This layer has the air we breathe and the clouds in the sky. The air is densest in this lowest layer. In fact, the troposphere contains three-quarters of the mass of the entire atmosphere. The air here is 78% nitrogen and 21% oxygen. The last 1% is made of argon, water vapor, and carbon dioxide. When you feel the wind on your face, see clouds in the sky, and watch a bird flap its wings in flight, you’re experiencing the troposphere. It’s a pretty nice layer to call home.
