Earth subsystems

1. Subsystems of
the Earth
Lesson 2

2. What I Need to Know

3.  The planet Earth is home to varied life forms
which interact continuously with the non-living
components.
 There are four subsystems that composed the
earth.
 Each of these systems, allow earth to keep
itself in balance. A change in one system will
affect other system.

5. A. Earth’s Systems
Directions: Supply the blanks
with the different subsystems
of the earth which are shown
through the illustration. Write
your answers in a sheet of
paper.

6. B. Intro to Earth Systems
Directions: Read the descriptions below (across and down)of
the terms asked in the puzzle.

7. ACROSS
4. the envelope of gases surrounding the earth or another
planet
7. is defined as a branch of biology focused in the study of the
relationships of the natural world
8. any of the almost spherical concentric regions of matter
that make up the earth and its atmosphere, as the lithosphere
and hydrosphere
9. the branch of science that deals with the physical and
biological properties and phenomena of the sea.
10. the science that deals with the earth’s physical structure
and substance, its history and the processes that act on it.
DOWN
1. all the waters on the earth’s surface
2. the branch of science that deals with celestial objects,
space, and the physical universe as a whole
3. the branch of science dealing with the physical
constitution of the earth and its atmosphere.
5. the regions of the surface, atmosphere and hydrosphere of
the earth
6. the branch of science concerned with processes and
phenomena

8. EARTH’S UBSYSTEMS

9. Earth’s Subsystems
 Earth is one of the inner planets in the solar system.
 According to radiometric dating record, it is said to
be 4.56 billion years old.
 It is the only planet in the solar system to harbor life.
 Earth is a closed system.
 Biogeochemical cycles drive the Earth’s
subsystems.

10. 1. Atmosphere
 A set of layers of gases that
blankets the planet held by the
planet’s gravity.
 It is consisted of 78% nitrogen,
20.95% oxygen, 0.93% argon
and 0.04% water vapor including
all other gases.
 Different layers of the
atmosphere include the
troposphere, stratosphere,
mesosphere and thermosphere.

11. 2. Hydrosphere
 It is the liquid component of the Earth
including oceans, glacial waters, and
freshwater bodies that covers 70% of
the earth’s surface; 98% of the water
on Earth is saltwater.
 All liquid water runs down hill.
 It starts as fresh water in the high
areas and runs down hill until it
reaches the ocean.

12. The hydrosphere is made up of all the
salt water and fresh water on Earth.
Salt water in the
oceans and seas.
Fresh water in the lakes, rivers and
streams and the frozen water on Earth.

13. 3.Geosphere
 It is the solid sphere of the earth.
 This is where geologic processes
such as volcanism and
orogenesis (mountain building)
take place.
 The lithosphere is a part of the
geosphere that is composed of
the solid, outermost part of the
planet.

14. 4. Biosphere
 This is the living sphere
of the earth.
 It is the totality of all the
ecosystems in the whole
planet.
 It compels us to interact
with other living
organisms with the
influence of the abiotic
factors in the system.

15. Biosphere continued…
This
includes all
the plants,
animals,
fungus,
protists
and
bacteria
on Earth.

16. The spheres / systems are endlessly interacting.
• Can you think of ways that they interact?
