Air Pollution• Smog is a thick haze of

fog and chemicals.• Smog occurs when

polluting chemicals mix with the ozone.

• It can be hazardous to breathing.

• Acid rain is a mixture of chemical air pollutants and precipitation.

• Acid rain can kill fish, eat away at buildings, and kill trees.

The Greenhouse Effect• The greenhouse effect is when gases in the

earth’s atmosphere trap the sun’s warmth. • Without the greenhouse effect, Earth would be

too cold to live on.• Some scientists believe pollution is

strengthening the greenhouse effect, making temperatures rise across the world.

• Rising temperatures could lead to polar ice caps melting and oceans flooding low coastal lands.

The Lithosphere• Lithosphere is another name for the earth’s crust.• Human activities such as farming, logging, and

mining can have negative effects on the lithosphere

Deforestation• Deforestation is the cutting down of trees

without replanting.• Without tree roots, topsoil can be lost when

wind or water carries it away.• Rainforests are being cut down at high rates. • This is a big concern because forests support

the water cycle and help replace the oxygen in the atmostphere.
