What is the water cycle?
a continuous pattern in nature in which water moves as it changes state above, on, and below the surface of the earth
What is the scientific definition of melting?
the change of state from a solid to liquid; occurs when a solid gains thermal energy
What is sublimation?
the change of state from a solid to a gas without first becoming a liquid; occurs when a solid gains thermal energy
What is evaporation?
the change of state from a liquid to a gas; occurs when a liquid gains thermal energy
What is condensation?
the change of state from a gas to a liquid; occurs when a gas loses thermal energy
What is deposition?
the change of state from gas to solid; occurs when a gas loses thermal energy
What is the scientific definition of freezing
the change of state from a liquid to a solid; occurs when a liquid loses thermal energy
What is thermal energy?
the energy that is generated and measured by heat. An example of thermal energy is the kinetic energy of an atom or the chemical energy in a molecule
What is runoff?
water from precipitation and snowmelt that flows over earths surface
What is ground water?
water that seeps through soil and cracks in rock; source of water for underground springs and wells
What is aquifer?
a geological formation of loose rock or soil that is saturated with ground water
What is Water table?
the depth at which loose rock and soil below earths surface are saturated with water; the upper boundary of an aquifer
What is precipitation?
solid to liquid water that falls to earths surface
What is a polar ice sheet?
a frozen field of ice covering either the north pole or the south pole
What is an ice cap?
a large area of ice that permanently covers land
