Types of Pollution
Nutrient
Sediment
Bacterial
Toxic
What are they?
Toxic Pollution- is the presence of pesticides, oil, industrial waste, household chemicals, mining waste, lead, and radioactive nuclear waste in the water.
Sediment Pollution- it is the presence of excessive silt and clay in water.
Nutrient Pollution- is the presence of excess nitrogen and phosphorus in the water.
Bacterial Pollution- it is the presence of harmful bacteria in water supplies.

What are Household Energy Usage
Household Energy Usage is all of the electrical appliance in your house.
Electrical appliance in your home Examples
Examples-Computers, Air Conditioner, Electric Stoves, and the Water Heaters are all examples of electrical household appliances
What are Greenhouse Gases?

Greenhouse Gases- a gas in Earth's atmosphere that absorbs and then re-radiates heat.
Types of Greenhouse gases
Methane
Nitrous Oxide
Carbon Dioxide

The heat from the sun that gets trapped is used to warm our earth.

Without the greenhouse gas there wouldn't be as much heat
Increases the temperature and traps heat in our atmosphere and that keeps us warm
Voltage- (V) is a measure of how much electrical energy is in a circuit.
Current- (I) is a measure of the amount of electrical charge that passes through the circuit each second.
Wattage- (W) is the measure that is used by a device each second.
Energy Consumption (usage)- is the total amount of energy used in a given time period. It is measured in kilowatt-hours (kWh)
Ex- Incandescent lamp A type of light in which an electrical current passes through a thin tungsten filament, causing it to glow and give off light.
Ex- Fluorescent lamp a light source that consists of a glass tube coated with phosphor and filled with argon and another inert gas
Ex- Halogen lamp a type of lamp in which the tungsten filament is encased
in a capsule containing a mixture of gases that allow it to operate at a high temperature.
Lumen- a measure of the light produced by a lamp.
Units of wattage- include
the watt (W) and kilowatt (kW)
The carbon cycle is the cycle which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
What is the five Spheres?
Biosphere
Geosphere
Hydrosphere
Atmosphere

Carbon reservoir- a part of Earth that stores carbon.

Carbon sink- a carbon reservoir that absorbs carbon from the atmosphere and stores it for a long period of time.
Fossil fuel- a fuel that has formed over thousands or millions of years from the remains of living organisms.
Decomposer- an organism that absorbs nutrients from living things or the organic matter they leave behind, turning it into simpler inorganic matter.
Oxygen - a colorless, odorless gas in the air used by animals to get energy from food.
Producer- an organism that converts simple inorganic matter (such as water and carbon dioxide) into organic matter (like sugar and protein).
-
Biomass- the total mass of a group of living things.
Consumer-
an organism that feeds on organic matter because it cannot produce it.
Inorganic-
not produced by living things.
Organic-
produced almost exclusively by living (or once-living) things.
Organism-
a single living thing.
Population-
all the organisms of a certain kind in a particular place.
Water Vapor
AxV=W for voltage and wattage
