The spheres are the four subsystems that make up the planet Earth.
They are called spheres because they are round, just like the Earth.
The four spheres are the geosphere (all the rock and land on Earth), hydrosphere (all the water on Earth), atmosphere (all the gases surrounding Earth), and biosphere (all the living things on Earth).
Earth’s land makes up the geosphere.
Geo means “earth.” The Earth’s geosphere is the portion of the earth that includes rocks and minerals.
We rely on the geosphere to provide natural resources and a place to grow food. Volcanos, mountain ranges, and deserts are all part of the geosphere.
Put simply, without the geosphere, there would be no Earth!
Earth’s water makes up the hydrosphere.
Hydro means “water.“ The hydrosphere includes the oceans, rivers, lakes, groundwater, and water frozen in glaciers. 97% of water on Earth is found in the oceans. Water is one of the most important substances needed for life and makes up about 90% of living things.
Without water, life would not be possible.
Earth’s air makes up the atmosphere.
Atmos means “air.” The atmosphere includes all the gases surrounding the Earth. We often call the atmosphere “air.” All planets have an atmosphere, but Earth is the only planet with the correct combination of gases to support life.
The atmosphere consists of five layers and is responsible for Earth’s weather. Even though it seems like air is made of nothing, it consists of particles too small to be seen. All these particles have weight that push down on Earth. The weight of air above us is called air pressure.
Without air , life would not be possible.
Earth’s living things make up the biosphere.
Bio means “life.” biosphere is made up of all the living things on Earth and it includes fish, birds, plants, and even people.
The living portion of the Earth interacts with all the other spheres. Living things need water (hydrosphere), chemicals from the atmosphere, and nutrients gained by eating things in the biosphere.
Humans, animals and plant are part of the Biosphere
Basically:
Geosphere: Is the land on the Earth planet
Hydrosphere: Is the water around the Planet
Atmosphere: Is the air
Biosphere: All living things in the Planet
Time to do it!!
As this is going to be the last project, it has to be great!!!
I would like you to make a project where we can find an example the four “spheres”
Ex: land, water, air and living things
MATERIALS:
You can use everything you want (even a piece of paper and make a drawing if you do not feel like doing a great project)
Here I leave some examples:
In all of them we see a living thing (biosphere), water ( hydrosphere), land (geosphere) and air (atmosphere) represented
We are going to try this interactive worksheet:
You need to drag the answers to the correct place then, you can check if everything is correct.
Next, you need to send it to me. Write your name and year3 and then send to the teacher: santamartabilingual@gmail.com
As the water evaporates, vapour rise and condense at the top of the bag. That forms clouds
After a while, water droplets appear on the inside of the bag. As they become bigger, they slide downwards. That is the rain. That goes to the sea again.
