Global Warming: The temperature of the Earth has increased, which makes ecosystems unstable
Invasive species: Species that although live in a certain area, are not native and do not belong there

Nutrient pollution -
the presence of excess nitrogen and phosphorus in the water.Parts per million -
a measure of concentration.Bacterial pollution -
the presence of harmful bacteria in water supplies.What harmful effect does Nutrient Pollution have?
It can result in blooms of algae that die and deplete oxygen as
they decay. The lack of oxygen kills fish and other animals.Current is measured in
amperes (A)Energy consumption -
the amount of energy that is usedFluorescent lamp -
a light source that consists of a glass tube coated with phosphor and filled with argon and another inert gasHalogen 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.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.Voltage -
a measure of electrical potential energyWattage -
the electrical power consumed by a deviceVoltage is measured in
volts (V).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.Greenhouse gas
a gas in Earth's atmosphere that absorbs and then re-radiates heat.Hydrosphere
the water on a planet.Lithosphere
the rigid upper layer of the Earth.Consumer
an organism that feeds on organic matter because it cannot produce it.+2
not produced by living things.+2
- Climate change impacts farmers because warmer temperatures can lead to __ ___ that damage crops.
What is the difference between weather and climate?
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+1
What Is the difference between "Global Warming"and "Climate Change" ?
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+2
Scientists are highly confident that many of these observed changes can be linked to the climbing levels of ___ and other _ in our atmosphere, which are caused by ___.
CO2, greenhouse gases, human activity+1
Name 3 natural factors that influence Earth's climate-
