The document discusses the origins, structure, and subsystems of the Earth, highlighting key theories like the Big Bang and Steady State. It outlines the four subsystems of the Earth: atmosphere, biosphere, geosphere, and hydrosphere, detailing their roles and composition. The document also emphasizes the importance of these systems for life on Earth and includes a learning task related to the flow of matter and energy across these subsystems.

_____ 1. This theory states that God created the universe
in seven days
A. Aristotelian universe B. Creationist theory
C. Nebular Theory D. Primordial universe
_____ 1. The theory that states the universe developed
13.7 years ago and started as a very dense and hot
singularity.
A. Atomic universe B. Big Bang theory

15. • Opposes the Big Bang Theory
• Steady State theory states that the
universe has always been
essentially the same as it is today
and it will continue forever.
• The universe is expanding but it is
infinitely old. New galaxies
continually form in the gaps that
open up as the universe expands
• Creation of matter is an ongoing,
eternal process

32. The four subsystems of the earth

33. The four subsystems of the earth
1.Atmosphere
- The gaseous layer above the earth’s
surface , primarily composed of 78%
nitrogen, 21% oxygen and other gases like
argon, carbon dioxide, carbon monoxide
and other inert gases made the remaining
1%
- The atmosphere supports life indirectly by
regulating the climate .

34. 1.Atmosphere
- Air acts as both
blanket and filter,
retaining heat at
night and shielding
from direct solar
radiation through
the day

35. 2. Biosphere
- The zone of the earth where all forms
of life exist; in the sea, on land, and in
water. It sometimes called the large
ecosystem. This is the zone that life
inhabits. Biosphere is he very thin layer
above the earth’s surface.

37. 3. Geosphere
- The solid earth, consisting of the
entire planet from the center of the
earth to the outer crust. It includes
the core, mantle and the crust of the
earth.

39. 4. Hydrosphere
- The water part of the earth which
circulates among oceans , continents,
glaciers in the atmosphere. Oceans
cover 71% of the earth and contain
97.5% of its water.
