Question

Discuss and explain the diagram showing four systems of the earth

Answer 1

Answer:

Planet Earth is made up of four overlapping systems that contain all of world’s land masses, water sources, living organisms, and gases. These four systems are known as spheres.

Geographers break down the Earth’s systems into four spheres that make up the world’s air (atmosphere), water (hydrosphere), land (geosphere), and living organisms (biosphere).

Three of these spheres are abiotic and one sphere is biotic. Abiotic describes substances that are made from non-living materials. Biotic relates to living things like bacteria, birds, mammals, insects, and plants.
