landscape
runoff
scenery such as mountains, valleys, trees, rivers, and forests.
the flow of water, from rain, snowmelt, or other sources, over the land.
saturated
slope
thoroughly full.
used to describe the measurement of the steepness, incline, gradient, or grade of a
straight line.
stream
deposit
a body of water.
material added to a landform.
flood plains
sediment
flat or nearly flat land adjacent to a stream or river that experiences occasional or
periodic flooding.
is solid matter that floats in a liquid. Sediment often settles to the bottom after
a while.
tributaries
dam
a stream or river which flows into a mainstem (or parent) river, and which
does not flow directly into a sea.
a barrier that divides waters.
aerial drawing
canyon
a pictorial representation of earth as viewed from above.
a deep, narrow river valley
with steep slopes.
condensation
crevasse
the process by which a gas becomes a liquid. Water vapor turns into liquid water
by condensation.
a deep crack in a glacier.
deposition
erosion
When water or a
glacier lays down earth materials.
When earth
materials are broken down and
moved from place to place.
evaporation
flood
when a liquid
becomes a gas.
overflow of a body of water
beyond its banks or shore.
fog
glacier
very fine droplets of water suspended in the air at or near the surface of the earth.
a huge mass of ice that moves
very slowly over land.
ground water
hydroelectricity
water that has soaked into the soil.
electricity that is generated by waterpower.
iceberg
landforms
a large piece of ice that has broken off a glacier and has moved into the water.
the features of the earth’s surface, such as mountains, plateaus, and plains.
levee
meander
a bank along a stream or river that is intended to prevent flooding.
a large bend in a stream channel that develops when soil is eroded from one
bank and deposited on the other.
oxbow lake
precipitation
a lake that forms when a river breaks through the neck of a meander and moves
straight onward.
rain, snow, sleet, or hail.
reservoir
soil
a place where large amounts of water are stored for future use. Reservoirs are like
lakes; they may be natural or made by humans.
the top layer of earth. Soil is composed of organic materials (humus); inorganic
materials (sand, silt, and clay), water, and air.
surface water
valley glacier
water that stays on the earth’s surface rather than sinks into the soil.
a glacier that forms in the V-shaped valley formed by a river.
water cycle
water vapor
the process by which water moves through the ground, evaporates from earth into the air, forms clouds, and falls back to earth
as rain or snow.
water in its gaseous state.
weathering
the process by which earth materials are broken down by natural forces.
