Scratch- What would happen if parts of the water cycle were missing?

 

Biosphere Explantion

 Biosphere, Do you know what it is? The earth is made up of 4 main spheres: Biosphere, geosphere, atmosphere and the hydrosphere. Today I will be telling you about the biosphere and how it works.

What is the biosphere? 

The biosphere is all about life. It includes all living things like animals, plants, even us! Geographers use this term biosphere to describe our world. The biosphere goes all the way, Earth up to the upper areas of the atmosphere where birds and insects are found Without the biosphere, Earth will be lifeless.

P2 What are the main components of the biosphere?

There are 4 main components of the biosphere Sunlight, Water, Air and food. Sunlight is a necessity for all living things, as it is the main source of energy. The sun produces heat for animals, plants and us. Secondly, is water, it is an essential part of survival. Water is needed for cells and tissues to work. It is also an environment for animals. Air is next. Air is made up of several gases. Two most important gases of all are oxygen and carbon dioxide. Without oxygen, living things will die and without carbon-dioxide plants won’t survive. Lastly is food. Living things need energy for function. Energy is for growth, reproduction, movement and work.

P3 How does it work?

The biosphere is made of all living things but it includes all four spheres. For example, sea animals live in the ocean and that’s the hydrosphere and birds live in the sky and that’s the atmosphere and insect live underground and that’s the geosphere.

In conclusion, without the biosphere life wouldn’t be possible. The biosphere connects all the spheres together and makes Earth, Earth.
