False

Septic

Having pathogens.

? wastes are solid, liquid, or gas wastes that are toxic, flammable, corrosive, reactive, or radioactive.

Hazardous

The continuous movement of water between the Earth's surface and the atmosphere

Hydrological Cycle

? reduce the need for landfills by burning solid wastes

Incinerators

Pollutes water sources by dumping wastes in rivers, streams, and oceans

Industry

Watershed

Land that receives precipitation and slows its flow into waterways.

Waste is deposited into ? in thin layers which are then compacted and covered with soil.

Landfills

Troposphere

Layer of the atmosphere closest to the earth, containing most of the oxygen.

Aquifers

Layers in the earth's crust that hold water.

A metal that leaks into water supplies via the soil or aging water systems

Lead

Thermosphere

Next to the outermost layer of the atmosphere.

Discarded plastic, rubber, glass, and styrofoam are examples of ? wastes.

Nondegradable

Ozone

O3, a highly reactive oxygen molecule.

Ionosphere

Part of the atmosphere full of electronically charged particles.

A chemical pollutant that can enter the water cycle through agricultural or domestic use

Pesticides

Can cause the contamination of underground water supplies if poured on the ground

Petroleum

The decomposition of organic matter by microorganisms

Putrefaction

Improperly disposed of solid or hazardous wastes can affect the ? of water, soil, and air.

Quality

Precipitation

Rain, snow, hail, or sleet.

? is the process by which certain waste materials, such as plastic, glass, aluminum, and paper, are prepared for reuse.

Recycling

Stratosphere

Second layer of the atmosphere, contains the ozone.

The leading cause of water contamination in countries without water treatment plants

Sewage

Biodegradable

Susceptible to decomposition by living organisms.

Putrefaction

The decay of organic matter caused by microorganisms.

Atmosphere

The layers of air that surround the earth.

Mesosphere

The middle layer of the atmosphere.

Exosphere

The outermost layer of the atmosphere that extends into outer space.

Distillation

The process of purifying water by vaporizing and recondensing it.

Erosion

The wearing away of land by wind and water.

Water is supplied to us in ? forms.

Three

Soil is the ? layer of the earth's crust.

Top

Air pollution is the presence of harmful substances in the earth's atmosphere.

True

Pollution in the environment affects living things.

True

Refuse

Waste

Biodegradable

Waste that will decompose naturally without causing harm to the environment.

The ? slows runoff of rain water, helping to prevent floods and erosion.

Watershed

Inhabitant

A person or animal that lives in a particular place.

A source of water pollution caused by the overuse of pesticides and fertilizers

Agriculture

? wastes can be broken down by other organisms into a reusable form.

Biodegradable

A substance that naturally decomposes into harmless materials is called ?.

Biodegradable

? dispose of solid biodegradable wastes through the implementation of the process of decomposition.

Compost Piles

? is the principle natural means of recycling solid waste.

Decay

? water is pure

Distilled

Ions

Electronically charged particles.

Caused by an overabundance of organic matter in water supplies

Eutrophication

All of the earth's life and weather exists within the stratosphere.

False

The atmosphere is a combination of gases that encases and protects the moon.

False

The condition of the environment has no affect on its inhabitants.

False

The ozone layer is contained within the troposphere.

False
