An Environmental Balance

Chp 2-4

Earth’s Physical Geography

• Atmosphere- blanket of air surrounding the earth

• Lithosphere- earth’s land areas• Hydrosphere- all water on earth• Biosphere- allliving things and theirenvironment in whichthey live

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

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

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

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
