The Interdisciplinary Nature of Environmental Science Flashcards
surroundings that have the conditions for living organisms
environment
French Word where environment was derived from and its meaning
“Environ” - surrounding
Components of Environment
Hydrosphere, Lithosphere, Atmosphere, Biosphere
mantle of rocks constituting the Earth’s crust
lithosphere
includes all water bodies
hydrosphere
cover of the air; envelopes the earth
atmosphere
known as the life layer
biosphere
Five Concentric Layers of the Atmosphere
Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
% of all water vapor and aerosols in the troposphere
99%
most of Earth’s weather happens here; most aviation takes place here; almost all clouds are here
Troposphere
home to Earth’s ozone layer
Stratosphere
highest part of atmosphere that jet planes can reach
Stratosphere
stratosphere is located between:
12 and 50 km
mesosphere is located between:
50 and 80 km
coldest place found within earth system
Mesosphere
sounding rockets and rocket powered aircrafts can reach here
Mesosphere
thermosphere is between:
80 and 700 km
lowest part of the thermosphere contains the:
Ionosphere
both cloud and water vapor-free; auroras can be seen here
Thermosphere
the ISS orbits this atmosphere
Thermosphere
the exosphere is between:
700 and 1000 km
molecules found here are extremely low in density; doesn’t behave like gas
Exosphere
no weather at all and most satellites orbit here
Exosphere
interdisciplinary academic field that integrates physical and biological science, to the study of the environment, and the solution of environmental problem
Environmental Science
Goals of Environmental Science
- How Nature Works
- How Environment Affects Us
- How We Affect the Environment
- How to Deal with Environment Problem
- How Can We Live Sustainably
Importance of Environmental Science
- Environment issues being of international importance
- Problems cropped in the wake of development
- Explosive increase in pollution
- Need to save humanity from extinction
- Need for wise planning of development
recent changes that happened in the world
population exponential growth, climate change, urbanization, biodiversity loss, pollution
