BIOPHYSICAL ENVIRONMENTS
- ATMOSPHERE
- Structure of the atmosphere
- 1. troposphere
2. stratosphere
3. mesosphere
4. thermoshpere
- is the vast gaseous envelope of
air that surrounds the Earth
- insulates earth from extreme
temperatures
- Insolation = incoming solar radiatoin
- Negative Impacts on atmosphere
= fossil fuels green house gasses
hole in ozone layer global
warming
- LITHOSPHERE
- Parent Material
- provides starting point for soil
formation.
- Rocks high in silicia are high in acidity and
have low clay content and and low fertility eg
sand stone
- non acidic parent
material eg basalt are
high in iron and
magnesium. Important in
clay formation and often
fertile
- Definitions
- LITHOSPHERE: is the earths
surface and all its components and
inorganic mistures of rocks and soil
- WEATHERING: physical
disintegration and chemical
decomposition of land
- MASS MOVEMENT: down
slope movement of
weathered rock material
- EROSION: the
wearing away of land
by a force of water
- BIOSPHERE
- The biosphere is made up of the parts of Earth
where life exists. The biosphere extends from the
deepest root systems of trees, to the dark
environment of ocean trenches, to lush rain
forests and high mountaintops
- Origins of the Biosphere
- The biosphere has existed
for about 3.5 billion years.
The biosphere’s earliest
life-forms, called
prokaryotes, survived
without oxygen. Ancient
prokaryotes included
single-celled organisms
such as bacteria and
archaea.
- HYDROSPHERE
- Global Water Budget = Web definitions the balance of the volume of water coming and going between the
oceans, atmosphere, and continental landmasses
- HUMAN IMPACTS
- Climate Change
- Increase in natural disasters
- Burning of fossil fuels
- Tourisms effect on the environment
- Introduced species eg Bito Bush on sand dunes
