Halogen Lamp- type of lamp where the tungsten filament is encased in a capsule containing a mixture of gases that allow it to operate at a high temperature.
Usage- the amount of time an electrical device is used
Current is measured in amperes (A)
Lumen- a measure of the light produced by a lamp
Fluorescent Lamp- light source that consists of a glass tube coated with phosphor and filled with argon and another inert gas
Energy Consumption- the amount of energy that is used
Voltage- a measure of electrical potential energy
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
Wattage- the electrical power consumed by a device
Current- the flow of electrical charge
Voltage is measured in volts (V)
Units of wattage include the watt (W) and the kilowatt (kW)
Climate change impacts farmers because warmer temperatures can lead to drought conditions that damage crops
Global warming refers to the long-term increase in Earth's average temperature, climate change is the mean atmospheric conditions typically an average of 30 years of weather data. A mean, or average, is much less variable
Scientists are highly confident that many of these observed changes can be linked to the climbing levels of CO2 and other greenhouse gases in our atmosphere, which are caused by human activity.
Earth's average temperature is projected to rise another 0.5°F to 8.6°over the next hundred years
The Earth has experienced natural warming and cooling trends throughout its history
Climate change can cause more rain and flooding in certain areas
The increasing intensity of hurricanes over the past decades may be caused by climate change
Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time
Greenhouse Gas- a gas in Earth's atmosphere that absorbs and then re-radiates heat
Earth's average temperature has risen by 1.5°F over the past century
Rising global temperatures have been accompanied by changes in weather and climate
Glaciers are melting and causing ocean levels to rise as a result of climate change
When scientists discuss climate change, they refer to the overall trend in climate data.
Fossil fuel burning has caused the warming of the planet since the Industrial Revolution.
Biosphere- living things on a planet
Atmosphere- the gases that surround a planet
Hydrosphere- the water on a planet
Geosphere- the rocky, non-living parts on a planet
Sediment Pollution can harm marine plants and animals by blocking sunlight and covering sensitive organisms and can be especially devastating to coral reefs
Sediment Pollution- the presence of excessive silt and clay in water
Bacterial Pollution can cause sickness and infection
Toxic Pollution- the presence of pesticides, oil, industrial waste, household chemicals, mining waste, lead, and radioactive nuclear waste in water
Bacterial Pollution- the presence of harmful bacteria in water supplies
Nutrient Pollution can result in blooms of algae that die and deplete oxygen as they decay. The lack of oxygen kills fish and other animals
Nutrient Pollution- the presence of excess nitrogen and phosphorous in the water
Water Pollution- the introduction of harmful substances into water.
Concentration- the amount of substance in a given volume
Parts Per Million- a measure of concentration
Organism- a single living thing
Producer- an organism that converts simple inorganic matter (such as water and carbon dioxide) into organic matter (like sugar and protein)
Photosynthesis- a process in which plants use energy from light to change carbon dioxide and water into glucose (sugar) and oxygen
Carbon Sink- a carbon reservoir that absorbs carbon from the atmosphere and stores it for a long period of time
Consumer- an organism that feeds on organic matter because it cannot produce it
Carbon Reservoir- a part of Earth that stores carbon
Mean- the average of a group of numbers
Inorganic- not produced by living things
Biotic Factor- a living component of the environment
Decomposer- an organism that absorbs nutrients from living things or the organic matter they leave behind, turning it into simpler inorganic matter.
Abiotic Factor- a non-living component of the environment
Oxygen- a colorless, odorless gas in the air used by animals to get energy from food.
Organic- produced almost exclusively by living (or once-living) things
Population- alll the organisms of a certain kind in a particular place
Biomass- the total mass of a group of living things
Fossil Fuel- a fuel formed over thousands of years from the remains of living organisms
