Module 2 Flashcards
a complex system of interrelating physical, chemical, and
biological processes. It is a system in which sets of interconnected components are
interacting to form a unified whole.
Earth
four major smaller
systems known as subsystems.
atmosphere, geosphere, hydrosphere, and biosphere.
subsystems is also known as?
spheres of the Earth.
serves as the Earth’s blanket. Its name rooted from the Greek
word atmos which means gas and sphaira which means globe or ball.
Atmosphere
The air in the atmosphere is generally composed of
78% nitrogen, 21% oxygen, 0.9% argon and the remaining 0.10% is made up of
different trace gases and vapor.
vapor. It serves as the Earth’s protection form harmful
UV rays and keeps the planet warm through greenhouse gasses.
Atmosphere
comes from the Greek word geos meaning ground.
It pertains to the solid part of the earth.
Geosphere
three layers of earth
crust, mantle, and the core.
The three layers are composed of?
minerals, organic material or natural glass called rocks.
loose particles of rocks that enveloped the surface of Earth is called as?
regolith.
is composed of
all the water on Earth in any form. This includes ice, water vapor and liquid water.
Hydrosphere
The permanently frozen part of this subsystem is called
cryosphere.
It is composed of
all living things and the areas where they are found. It includes all animals,
microbes, and plants. It extends to the upper areas of the atmosphere where
insects and birds can be found. It also extends to the deep parts of the oceans
where marine organisms can still survive.
Biosphere
It is also in this zone that the interaction
between the different subsystems is most dynamic. In __________, each organism
plays an important role to the food web. If one is lost the others will be affected.
Biosphere
The processes that move matter and energy from one sphere to another
is called as
sphere interactions.
