ENVIRONMENTAL SCIENCE

ENVIRONMENTAL SCIENCE
1.Environmental science:
- atmospheric sciences
- ecology
- environmental chemistry
- geosciences
- environmental assessment
_ Atmospheric sciences -> the Earth’s gaseous outer layers with an emphasis on its relationship
to other aspects of biosphere
_ Ecology -> the dynamics of a species in a given area and some aspects of its environment
_ Environmental chemistry -> chemical alterations in the environment: soil contamination and
water pollution
_ Geosciences -> geology, physical geography, geomorphology
_ Environmental assessment -> a process of appraisal through which environmental protection
and sustainable development are considered
2. Both the Earth sciences and Environmental science deal with the process and change in our
natural environment
- Environmental science ->change made by human activities and subsequent implications for
ecosphere
- Earth sciences -> process and change within natural environment without the added factor of
human intervention
3. bio- connected to living things: biosphere
eco- connected to the environment: ecology
geo- related to the Earth: geology
inter- between: intervention
meteoro- related to weather: meteorology
ENVIRONMENTAL TECHNOLOGY
-Environmental technology is concerning cleaner energy sources, energy-efficient transportation
and building, pollution-preventive methods
-Environmental technology draws on many sciences such as chemistry, biology, ecology
- Environmental technology focuses on improving efficiency, capacity, availability of newer

power sources such as wind turbines, solar panel and developing relatively newer power sources
such as wave power, hydrogen fuel cells


-Environmental technology also focuses on ways of making buildings more energy-efficient
- Advances in Environmental technology is seeking newer power sources and reducing harmful
emissions
