100

Process in which a substance changes from a liqud to a gas is?



condensation

100

A storage location for a substance, such as water. The atmosphere is a reservoir for carbon dioxide is?



reservoir

100

Water that falls from the sky to Earth's surface; may take the form of rain, snow, sleet, hail, or freezing rain is?



precipitation



100

Where a stream meets a lake or, more usually, an ocean. The mixture of fresh and salt water attracts a large number of species and so estuaries have high biodiversity is?



estuary

100

A small body of freshwater, with no stream draining it; fed by an underground spring is?



pond

200

A bend or curve in a stream channel is?



meander

200

The amount of time, on average, a substance remains in a reservoir is?



residence time


200

The release of water vapor into the air through the leaves of plants is?



transpiration


200

The location where a stream forms, often high in the mountains is?



headwaters

200

Cold, nutrient-rich water that rises from oceanic depths is?

upwelling

300

The smaller of two streams that join together to make a larger stream is?



tributary


300

Water in the form of a gas. Water vapor is invisible to humans; when we see clouds, we actually are seeing liquid water in the clouds is?



water vapor


300

Where a stream meets a large body of standing water, usually the ocean is?



base level


300

Where a stream enters a larger body of water such as a lake or an ocean is?



mouth


300

Ocean water that sinks due to higher density is?



downwelling

400

The upper part of a glacier where the amount of snow and ice that accumulates is greater than the amount that melts off is?



zone of accumulation


400

Process in which a substance changes from a liqud to a gas is?



evaporation


400

Where two streams join together is?



confluence

400

The region near a stream bed where water from the stream overflows during floods is?



floodplain


400

A horizontal movement of ocean water, caused by surface winds is?



surface current


500

Temperature and salinity driven currents that drive deep ocean circulation is?



thermohaline circulation


500

The movements of water in and between reservoirs like oceans, clouds, streams, ice, and ground water is?



water cycle


500

A ridge that separates one water basin from another is?



divide

500

A large body of freshwater drained by a stream, naturally occurring or human-made is?



lake

500

The regular rising and falling of Earth's surface waters twice a tidal day as a result of the Moon's and Sun's gravitational attraction is?



tide
