1. An Environmental Balance
Chp 2-4

2. Earth’s Physical Geography
Atmosphere- blanket of air surrounding the earth
Lithosphere- earth’s land areas
Hydrosphere- all water on earth
Biosphere- all
living things and their
environment in which
they live

3. Atmosphere and Air pollution
Fumes and chemicals from cars and factories pollute the air
Air pollution also includes more solid particles such as ash or dust
Air can become harmful to breathe
GLOBAL EFFECTS OF AIR POLLUTION
a. Global warming b. Ozone depletion
c. Acid rain

4. Atmosphere and Air pollution
Air pollution can affect the ozone layer- this layer serves as a protective shield as it filters out harmful rays from the Sun
Acid rain kills fish and eats away from the surface of buildings- it can destroy entire forests

5. Lithosphere Everything we use comes from land resources
To get these resources, top soil must be removed, which can results in harmful effects on the environment

6. Biosphere The more we expand, the more we disturb ecosystems
Ecosystems: places where the plants and
animals are dependent
upon one another and
their surroundings for
survival
Ecosystems are found
everywhere in the world
