Why does something sink? Sinking is when something heavy goes down the water.
Why does something semi-floats? Semi-float is when you can see the object at the bottom and the top.
Notes/Ideas: Things float because they have air in it or they are light. Things that sink are because they are heavy and have no air in them. Example, when people die in water they float because their blood is gone. Cruise ships float because of the air and the shape of it. A bowling ball will sink because of its mass and the basketball will float because it has air in it. If you take a bath and sit in the bathtub, the water will rise because of your mass and how much space you take up. Submarines can sink and float because when they have air or water they float but when they have no air or water, they will sink!

Introduction - what are the 4 spheres? What’s this report about?
There are four spheres that make up the earth. It is the Geosphere, Biosphere, Hydrosphere, Atmosphere. All these spheres contain something important that makes the earth what it is.
The Geosphere describes the land and rocks on the planet. From the tiny grains of sand to the big borders all live in the Geosphere. Geo comes from the greek word ground. Everything that lives in the Geosphere is not living, like they are all dead and not alive but some all the living things live in the next sphere that we are going to talk about.
The Biosphere has all the living things in it. All the animals, trees, grass, etc. Bio comes from the greek word Life. All types of animals, plants, humans even are from the Biosphere. Some of the animals live in the next sphere.
The Hydrosphere contains all the water on earth. Rain drops, water, seawater and liquid come from the Hydrosphere. Hydro comes from the greek work for Water. The water cycle is also in and from the Hydrosphere. Ice is also a part of the Hydrosphere.
The Atmosphere in the final sphere I will be talking about. It contains all the air and gases. For example, the air in the atmosphere and all the layers, gases from our vehicles. Atmo comes from the greek word Air.
Conclusion - what was this about? This was all about the 4 spheres of the earth. Geosphere, Biosphere, Hydrosphere, Atmosphere. All these spheres help each other so that the earth can be what it is.
