This document discusses different types of environments. It defines environment as the sum of all surroundings, including natural forces and living things. Environments can be categorized as built, natural, or social. The built environment refers to human-made surroundings like buildings and infrastructure. The natural environment includes living and non-living things found naturally on Earth, like various rock layers, bodies of water, the atmosphere, and biosphere.

For instance, when we say that, the natural environment of
giraffes is the savanna.

7. Composition Natural Environment
i. The Lithosphere: The lithosphere is the rigid outermost shell of a
rocky planet defined on the basis of the mechanical properties.
ii. The Hydrosphere: The hydrosphere refers to the combined mass of
water found on, under, and over the surface of the planet. Ocean,
rivers, lakes, ponds and as a whole all the water body of the earth.
iii. The Atmosphere: The atmosphere of Earth is a layer of gases
surrounding the planet Earth that is retained by Earth's gravity. The
atmosphere protects life on Earth by absorbing ultraviolet solar
radiation, warming the surface through greenhouse effect, and
reducing temperature extremes between day and night.

8. iv. The Biosphere: The biosphere is the global sum of all ecosystems.
It can also be termed the zone of life on Earth, a closed system and
largely self-regulating.
The biosphere is the global ecological system integrating all living
beings and their relationships

9. Social Environment
The social environment refers to the immediate physical and social
setting in which people live or in which something happens or develops.
