envisci midterm Flashcards
is the surrounding external conditions influencing development or growth of
people, animal or plants; living or working conditions etc.
Environment
living organisms (e.g., humans, animals, plants)
biotic
non-living things (e.g., Earth, wind, water, Sun).
abiotic
is the sum total of all the external forces, influences and conditions, which
affect the life, nature, behavior and the growth, development and maturation of living
organisms.
Environment
vapor or
air
“atmos”
ball, globe
“sphere”
It sustains life on the earth.
THE ATMOSPHERE
It comprises of 78% nitrogen,
21% oxygen, and smaller
amounts of
argon, carbon
dioxide, helium, and neon.
Reaches 12 km from the Earth’s surface
TROPOSPHERE
The thinnest layer of the atmosphere
TROPOSPHERE
Comprises roughly 80% of the weight of the atmosphere
TROPOSPHERE
Ozone Layer is located
STRATOSPHERE
Reaches 50 km from the Earth’s surface
STRATOSPHERE
a protective layer of O3
compounds that prevent ultraviolet radiation in directly
entering the Earth’s surface
Ozone Layer
Extends between 50 km and 70 km from the Earth’s surface
MESOSPHERE
Coldest layer of the atmosphere
MESOSPHERE
Contains only 0.001% of the gases in the atmosphere
THERMOSPHERE
Hottest layer of the atmosphere
THERMOSPHERE
Contains the Ionosphere, where aurora phenomena occur
THERMOSPHERE
Outermost layer of the atmosphere
EXOSPHERE
Extends as far as 6000 miles out into the space
EXOSPHERE
water
“hydro”
ball, globe
“sphere”
comprises all types of water resources oceans, seas, lakes, rivers, streams, reservior,
polar icecaps, glaciers, and ground water.
Hydrosphere
% of the earth’s water supply is in the oceans,
97
% of the water resources is locked in the polar icecaps and glaciers.
2
% is available as fresh surface water-rivers, lakes streams, and ground water fit to be used
for human consumption and other uses.
1
rock,
solid rock
“lithos”
– ball, globe
“sphere”
is the outer part of the solid
earth.
Lithosphere
lithosphere consist of
crust and Outermost layer of the mantle
about
60 miles (100 kilometers) in thickness
Outermost layer of the mantle
life or living
“bios”
indicates the realm of living organisms and their interactions with environment, via
atmosphere, hydrosphere, and lithosphere.
Biosphere
is systematized knowledge derived from and tested by recognition and formulation of a
problem, collection of data through observation, and experimentation.
Science
deals with the study of people and how they live together.
Social Science
deals with the study of nature and physical world. It includes such diverse disciplines
as biology, chemistry geology physics, and environmental science.
Natural Science
It is the study of living organisms and how they interact with our environment.
ENVIRONMENTAL SCIENCE
is a profession that applies science and mathematics to make the properties of matter and
sources of energy useful in structures, machines, products, systems, and processes.
Engineering
