LE2 Flashcards
It is a popular expression for the more scientific term acid deposition, which refers to the many ways in which acidity can move from the atmosphere to Earth’s surface.
Acid Rain
_________ is capable of affecting landscapes and the living things that reside within them even when precipitation is not occurring.
Acid Deposition
_______ is a measure of the concentration of hydrogen ions (H+) in a solution.
Acidity
________ have a profound effect on the energy budget of the Earth system despite making up only a fraction of all atmospheric gases.
Greenhouse Gasses
________ is the primary greenhouse gas, responsible for about three-quarters of emissions. It can linger in the atmosphere for thousands of years.
Carbon Dioxide (CO2)
_______ is released from landfills, natural gas and petroleum industries, and agriculture (especially from the digestive systems of grazing animals).
Methane (CH4)
_______ occupies a relatively small share of global greenhouse gas emissions—about six percent—but it is 264 times more powerful than carbon dioxide over 20 years, and its lifetime in the atmosphere exceeds a century, according to the IPCC.
Nitrous Oxide (N20)
_______ is the long-term warming of the planet’s overall temperature.
Global Warming
It refers to changes in weather patterns and growing seasons around the world.
Climate Change
________ the release of substances into subsurface groundwater or into lakes, streams, rivers, estuaries, and oceans to the point that the substances interfere with beneficial use of the water or with the natural functioning of ecosystems.
Water Pollution
_________ are concerned with controlling pollution from human activity so as to ensure that the water is suitable for its intended uses.
Water Quality Management
It is also the science of knowing how much waste is too much for a particular water body.
Water Quality Management
WATER POLLUTANT: Point sources
- Domestic Sewage
- Industrial Waste
It consists of wastes from homes, schools, office buildings, and stores
Domestic Sewage
WATER POLLUTANTS: Nonpoint Sources
- Urban Runoff
- Agricultural Runoff
_______ describes the movement and conservation of water on earth.
Hydrological Cycle
Water is transferred to the earth’s atmosphere through two distinct processes:
- Evaporation
- Transpiration
This cycle includes all of the water present on and in the earth, including salt and fresh water, surface and groundwater, water present in the clouds and that trapped in rocks far below the earth’s surface.
Hydrological Cycle
It is the conversion of liquid water from lakes, streams, and other bodies of water to water vapor.
Evaporation
It is the process by which water is emitted from plants through the stomata, small openings on the underside of leaves that are connected to the vascular tissue.
Transpiration
A third process is derived from the two and is called _________.
Evapotraspiration
