vocab
"______"is a river or stream that enters a larger body of water, especially a lake or river. The receiving water into which a "______" feeds is called the “mainstem,” and the point where they come together is referred to as the “confluence.”
"_____" is an area of land that channels rainfall, snowmelt, and runoff into a common body of water. The term “watershed” is often used interchangeably with “drainage basin,” which may make the concept easier to visualize
watershed
water containing less than 1,000 milligrams per liter of dissolved solids, most often salt. As a part of the water cycle, Earth's surface-water bodies are generally thought of as renewable resources, although they are very dependent on other parts of the water cycle.
freshwater
is simply a substance that can dissolve other molecules and compounds, which are known as solutes. A homogeneous mixture of "____" and solute is called a solution, and much of life's chemistry takes place in aqueous solutions, or solutions with water as the "_____"
solvent
the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
water cycle
"_______"is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high "________", meaning it takes more energy to increase the temperature of water compared to other substances
specific heat
Surfaces that don't allow water to pass through such as roads,homes and parking lot to list a few
impermeable
is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground.
aquifer
Although the net charge of a water molecule is zero, water is "___" because of its shape. The hydrogen ends of the molecule are positive and the oxygen end is negative. This causes water molecules to attract each other and other "___" molecules.
polar
the area of land from which all surface run-off flows through a sequence of streams, rivers and, possibly lakes into the sea at a single river mouth, estuary or delta.
river basin
"_____" a part of the natural water cycle Some part of the precipitation that lands on the ground surface infiltrates into the subsurface. The part that continues downward through the soil until it reaches rock material that is saturated is groundwater recharge.
groundwater
Water is called the "_________" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.
Universal solvent
"_________"is the binding or attraction between dissimilar molecules, atoms, surfaces, or substances. The adhesive forces that bind two dissimilar substances or surfaces are electrostatic forces and mechanical forces.
adhesion
"___________" refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.
cohesion
