A substance sticking to another surface, like Water sticking to a mirror.

A substance sticking to another of the SAME substance, like water droplets merging.

Water stored and flowing under ground, eventually getting into a lake, river, or ocean.

The energy found in the average speed of moving atoms. Faster atoms are hotter.

The amount of heat required to raise the temperature of a substance. Water has high specific heat.

The tension of the surface of a liquid that can support solid objects, like a paper clip on water.

All the waters on the earth's surface, such as lakes and seas, rivers, and even the clouds in the sky.

The quality of a solid that allows liquids to get through it.

The upper most zone of the ocean that still receives sunlight.

Water has poles, like a magnet. Hydrogen atoms gives a slightly positive charge, the oxygen a slightly negative.

The region of land that feeds a river its water.

Sensitive living things, like insects and fish, that can help us determine the general health of a habitat with their presence.

The amount of oxygen in water as tiny gas particles (not part of the water molecule). Fish need this to breathe.

Environmental Protection Agency (EPA)

Federally run agency that protects the environment through regulation and enforcement.

A natural chemical that can pollute waters if there is too much. Can come from fertilizer and run off from farms.

Scale of acidity from 0-14. low ph is high in acids, high ph is high in alkaline, and 7 is neutral and healthy for water.

Chemical that pollutes water, causing algae blooms.

The amount of dissolved salt in water.

A measure of how clear or cloudy water appears. High turbidity is foggy, muddy, or murky water.

Water that travels from one place to another on the ground, can cause flooding.

A river or stream that runs into a larger body of fresh water.

salty water that is fresher than sea water, like water in estuaries. Lower Salinity.

Some rare living things can make biomass from chemicals instead of sunlight. They live by hydrothermal vents.

Nutrients rise on these cold underwater currents from the deep ocean to the shallow.

pollution discovered in a wide area found in ground water or as sediments.

Pollution coming from a direct location, like an oil spill or fallen trash can.

Term	Definition
Adhesion	A substance sticking to another surface, like Water sticking to a mirror.
Cohesion	A substance sticking to another of the SAME substance, like water droplets merging.
Ground Water	Water stored and flowing under ground, eventually getting into a lake, river, or ocean.
Heat Energy	The energy found in the average speed of moving atoms. Faster atoms are hotter.
Specific Heat	The amount of heat required to raise the temperature of a substance. Water has high specific heat.
surface tension	The tension of the surface of a liquid that can support solid objects, like a paper clip on water.
Hydrosphere	All the waters on the earth's surface, such as lakes and seas, rivers, and even the clouds in the sky.
Hydrothermal vents	Volcanic vents under the ocean
Permeability	The quality of a solid that allows liquids to get through it.
Photic Zone	The upper most zone of the ocean that still receives sunlight.
Water Polarity	Water has poles, like a magnet. Hydrogen atoms gives a slightly positive charge, the oxygen a slightly negative.
River Basin	The region of land that feeds a river its water.
Bio-Indicators	Sensitive living things, like insects and fish, that can help us determine the general health of a habitat with their presence.
Dissolved Oxygen	The amount of oxygen in water as tiny gas particles (not part of the water molecule). Fish need this to breathe.
Environmental Protection Agency (EPA)	Federally run agency that protects the environment through regulation and enforcement.
Nitrates	A natural chemical that can pollute waters if there is too much. Can come from fertilizer and run off from farms.
PH level	Scale of acidity from 0-14. low ph is high in acids, high ph is high in alkaline, and 7 is neutral and healthy for water.
phosphates	Chemical that pollutes water, causing algae blooms.
potable water	Drinking water, which is rare.
Salinity	The amount of dissolved salt in water.
Turbidity	A measure of how clear or cloudy water appears. High turbidity is foggy, muddy, or murky water.
Runoff	Water that travels from one place to another on the ground, can cause flooding.
Tributaries	A river or stream that runs into a larger body of fresh water.
Brackish water	salty water that is fresher than sea water, like water in estuaries. Lower Salinity.
Chemosynthesis	Some rare living things can make biomass from chemicals instead of sunlight. They live by hydrothermal vents.
Upwelling	Nutrients rise on these cold underwater currents from the deep ocean to the shallow.
Nonpoint pollution	pollution discovered in a wide area found in ground water or as sediments.
Point Pollution	Pollution coming from a direct location, like an oil spill or fallen trash can.
