4 horizons of soil

clay, silt, sand, and loam

4 main types of soil

mineral particles, organic matter, water, air

4 major components of soil

gasoline, oil, and salt pollute rivers and lakes - nonpoint pollutions

Describe how runoff from roads can harm the environment? Is this point or non-point pollution?

land - radioactive waste dump water - plant discharges, sewage

Give land and two water pollution examples (point-source)

land - microbes water - debris, runoff used on crops

Give one land and two water pollution examples

volatile compounds created by polluted earth go into the atmosphere

How can land pollution become air pollution?

If a septic tank is too close to a hill or well, wastewater can flow to the well.

How can septic tanks lead to pollution?

How can we fix water pollution?

-factories can recycle water -farmers can use runoff water for irrigation -farmers can plant fields of grass that filter out pollutants before they reach the water

How can we prevent water pollution?

fertilizers speed up eutrophication

How does agricultural runoff contribute to eutrophication?

Sulfur dioxide and nitrogen oxide released into the air turns into acid rain.

How does smog and exhaust increase water pollution?

1. planting vegetation in areas prone to erosion 2. household chemical disposal 3. proper use of chemical killers

How to prevent soil pollution?

1. Kind of material 2. How much material 3. C:N ratio 4. Kind of soil 5. Growing conditions 6. How long the material has been there 7. Immediate danger to people and animals

Seven factors you need to know for remediation

cancer and tissue problems

What are some of the consequences of soil pollution?

human waste, industrial waste, and chemical runoff

What are the three main sources of pollution?

biochemical oxygen demand

What does BOD stand for?

DDT is a pesticide. DDT thins the eggshells of birds. The two animals we talked about were the bald eagle and the crane.

What is DDT? How does it impact the environment? What are two animals we discussed that were harmed by DDT?

Human waste is sewage and if the sewers overflow, it can pollute surface water.

What is human waste pollution and how does it harm the environment?

cleaning the soil - excavation, washing, changing properties of contaminants

What is remediation and what are some remediation processes?

acid rain

What major water pollutant does smog contribute to?

plants, animals, and humans are affected by lack of nutrients

Why is it important to prevent land pollution?

pollutant

any substance that can harm the environment

soil pollution

contamination of soil by harmful pollutants

pollution

contamination of the environment by harmful substances

soil

critical to life - made up of water, air, mineral particles, and organic matter

industrial waste pollution

fog and smoke that comes from factories and goes into the atmosphere and turns into acid rain

heat pollution

hot water from factories that once released into streams kills fish and other living things

open dumping, fly dumping, midnight dumping

names for illegally dumping trash

point source pollution

pollution that comes from a specific origin

nonpoint pollution

pollution that doesn't have a specific origin

agricultural runoff

runoff and irrigation water carry away pollutants from farm fields such as pesticides and fertilizers
