Introduction
The Earth consists of four subsystems,
across whose boundaries matter and
energy flows, the atmosphere (air),
biosphere (living things), hydrosphere
(water), and geosphere (land).
Because these subsystems interact
with each other and the biosphere,
they work together to influence the
climate, trigger geological processes,
and affect life all over the Earth.
The geosphere includes the rocks and minerals on Earth from the molten
rock and heavy metals in the planet’s center to the sand on beaches and
mountain tops.
The hydrosphere is made up of the total amount of water on
Earth, such as seas, oceans, rivers, etc.
The hydrosphere is significant since it keeps the Earth’s
temperature balanced. It is also the most crucial role in the
ecosystems as it gives living organisms water and supports
plant growth through the water cycle.
The abiotic components of soil and animal bones that may
become fossilized over the course of geologic time are
considered to be a part of the geosphere.
Why is the Geosphere important?
It provides the natural resources and
minerals to humans and to be able to
grow food.
Like the other three subsystems the
Geosphere is also necessary for life.
The Earth’s atmosphere is the gaseous
layer that envelopes the world.
The Earth’s atmosphere is held around the
planet with the force of gravity.
The common term for the atmosphere is
“air”.

THE
SUBSYSTEMS
OF EARTH
ATMOSPHERE
Why is the Atmosphere important?
Protects Earth's Biosphere from harmful solar
radiation.
Cycles heat, water, and necessary chemicals through
the climate system.
BIOSPHERE
Why is the Hydrosphere important?
Keeps the Earth’s temperature cool
through heat distribution.
Supports life to all ecosystems through
bodies of water and the water cycle.
Affects the weather and weather
patterns.
The biosphere is the thin life-supporting
stratum of Earth’s surface, extending from a
few kilometers into the atmosphere to the
deep-sea vents of the ocean. It is composed
of living organisms and non-living factors
from which the organisms derive energy and
nutrients.
Why is the Biosphere important?
Little changes in the biosphere can cause a large
impact on the lives of living organisms.
It promotes life on Earth by adapting to various
environmental changes, and favorable climatic
conditions.
How are they interconnected?
01 | Geosphere
Biosphere - receives sunlight and gases from the Atmosphere. It
collects water from the Hydrosphere and a living medium from
the Geosphere.
Hydrosphere - rain comes from the Hydrosphere, it falls from
the clouds at the Atmosphere to the Lithosphere and forms
streams and rivers that provides drinking water for wildlife.
Atmosphere – the Atmosphere provides the Geosphere with
heat and energy needed for rock breakdown and erosion. It
includes the mixture of gases that surround the planet.
02 | Atmosphere
Geosphere - Gases emmited from volcanic eruptions
have warming and cooling impacts on the Atmosphere.
Biosphere - Exchanges of carbon dioxide and oxygen
occur between the the Atmosphere and Biosphere in a
process called the photosynthesis-respiration cycle.
Hydrosphere - Evaporation of water in the
Hydrosphere adds water vapor to the Armosphere, a
process that requires energy input.
03 | Hydrosphere
Geosphere - Bodies of water erode the lands and
change their appearances overtime.
Biosphere - Bodies of water such as lakes support
the living organisms in the biosphere.
Atmosphere - The water cycle is a process that
involves both the hydrosphere and the atmosphere.
04 | Biosphere
Geosphere - The geosphere provdes a living
medium for the Earth's ecosystems to survive and
thrive.
Hydrosphere - The hydrosphere provides water for
the biosphere to function, grow, and live.
Atmosphere - The release of carbon dioxide into
the atmosphere completes the biological part of the
carbon cycle.
