A few weeks ago, we discussed Earth Science and discovered how much we truly don't know about the different parts of the Earth and which parts we were not too confident on. My partner and I decided that we were not that knowledgable on the Earth's Atmosphere. From this, we had to create a presentation that we would share with our peers. We created a Glogster that was all about the Earth's Atmosphere. I learned a lot from doing this assignment, not only about the Earth's Atmosphere, but also about the frustrations that can come from using Glogster!
We learned that the Earth’s atmosphere is broken up into several distinct layers. We live down in the troposphere, where the atmosphere is thickest. Above that is the stratosphere, then there’s the mesosphere, thermosphere and finally the exosphere. The top of the exosphere marks the line between the Earth’s atmosphere and interplanetary space.
The atmosphere is a mixture of nitrogen (78%), oxygen (21%), and other gases (1%) that surrounds Earth. High above the planet, the atmosphere becomes thinner until it gradually reaches space. It is divided into five layers. Most of the weather and clouds are found in the first layer.
The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun's dangerous rays from reaching Earth. It traps heat, making Earth a comfortable temperature. And the oxygen within our atmosphere is essential for life.
The atmosphere is the blanket of gases which surrounds Earth. It is held near the surface of the planet by Earth's gravitational attraction.
Without the atmosphere there could be no life on Earth.
The atmosphere contains the air we breathe;protects life from harmful radiation from the Sun;
helps keep the planet's heat from the Sun from escaping back into space; is a major element of the water cycle and keeps the climate on Earth moderate compared to that of other planets.
There are 5 layers:
-Exosphere
-Thermosphere
-Mesosphere
-Stratosphere
-Troposphere
