Explanation- The Four Spheres
Some of you maybe thinking what are the four spheres? What even are spheres? Well there are four spheres they are called the Biosphere, Geosphere, Hydrosphere and Atmosphere. Also I will be mentioning what the spheres are, and how they work together. An interesting fact is that the start of all of these spheres is a Greek word. So Bio is Greek for life, Geo is Greek for Ground, Hydro is Greek for water and Atmo is Greek for air.
Biosphere
The Biosphere is all living things like trees, plants, grass and so on. The Biosphere and the Hydrosphere works together. How? You may think. Well the Biosphere is all living things as I said, like trees, grass plants and other things as well. The Hydrosphere gives them water so they can become apart of the Biosphere.
All of the four spheres help the Biosphere. The Geosphere gives the Biosphere a home to live in. Because the Geosphere is dirt well the ground. So when a seed goes into the ground like a tree or something like that, the Geosphere gives it a home to grow roots.
How the Atmosphere helps the Biosphere is that plants, trees needs oxygen. The Atmosphere is oxygen a.k.a air. Another good thing about the Biosphere is that when the Atmosphere gives the trees oxygen we breath in air and out again. When we breath out the trees do something with the air. So the Atmosphere and people are helping the Biosphere.

Geosphere
The Geosphere is non-living things like rocks. But what you may not of known about the Geosphere is that, there is layers of the Geosphere. Did you know the crust of the earth is three times thicker under the ocean!
The first layer of the earth is the crust. The earths crust extends to about twenty-five miles. Did you know the crust of the earth is three times thicker under the ocean! Anyways after the crust there is the mantle. Did you know the Mantle is the largest layer of the earth? So Geosphere is the largest layer of the earth.
The first fifty miles of the mantle is very hard rigid rocks. After that about 150 miles of the mantle is super hard solid rock. Several hundred miles is made up of super hot rock. Goss is this mantle ever gonna end? Any ways lets skip to the inner core. The inner core is the hottest part of the earth and it is as hot as the suns surface. Some of you may wondering why hasn't it cooled down after all these years? Well the truth is that it is cooling this very moment.

Lets go back up to the surface. How does the Geosphere work with all the spheres? The Geosphere is solid ground. So like soil, concert all that stuff. So how I think the Geosphere works with the Biosphere is that it gives the Biosphere a home. How it works with the Hydrosphere is the Geosphere is a riverbed so the Geosphere provides a home for rivers,lakes and the sea. How it works with the Atmosphere is that the Geosphere is held down with gravity.
Hydrosphere
The Hydrosphere would have to be the most Interesting sphere. The Hydrosphere is all about water which means there is a water cycle. There are three stages to the water cycle. The first one is Evaporation. Evaporation comes from the heat of the sun. The heats warms up all the groundwater and then changes from liquid to a gas. Before it is just about to go to the clouds it is the second step of the water cycle. The second step is called Condensation. This is when it starts drifting up to the clouds. But what changes it into rain is the third step of the water cycle. The third step is call Precipitation which turns it into rain. When the cloud gets to heavy it drops the rain. But it is just not rain, it could be snow, sleet or hail. Then it does it all over again.
Any water can be used for the water cycle like salty or fresh water. 97% of earth is salty water and 39% is fresh water. But what are some problems that the water cycle would face from us humans? The water is getting pollutant, people throwing rubbish into lakes or rivers and other problems.
Atmosphere
Did you know that there is 5 layers of the Atmosphere. The first one is called the Troposphere. The Troposphere is the lowest Atmosphere. It extends to 4-10 miles out. Oh and did you know the higher a plane goes the more it gets colder. Anyways the second part of the Atmosphere is called the Stratosphere. At the Stratosphere you will find the ozone layer and where you will find planes zooming around. The Stratosphere extends to about 30-35 miles out.
The third layer if the Atmosphere is the Mesosphere. The Mesosphere extends out to 50 miles and where you will find meteors burning. The fourth layer of the Atmosphere is called the Thermosphere. The Thermosphere has lonosphere in it and fin electrically charge here. The lonosphere helps to transmit radio waves. Also the air is very thin in the Thermosphere but it extends about 400 miles out. The last layer of the Atmosphere is called the Exosphere. The Exosphere also has thin air like the Thermosphere. The Exosphere extends to about 6200 miles from Earth's surface.
