vocab 1
the continuous movement of water between the atmosphere, the land, and the oceans
water cycle
one of the bends, twists, or curves in a low gradient stream or river
meander
What factors affect a water budget
temperature, vegetation, wind, and the amount of rainfall
How does a river develop
A river develops over time, through the process of precipitation and erosion.
What are the 2 types of stream deposition
Two types of stream depositions are deltas, which form in water, and alluvial fans, which form on land.
the total loss of water from an area, which equals the sum of water lost by evaporation from soil and other surfaces and the water lost by transpiration from organisms
evapotranspiration
a fan shaped mass of rock material deposited at the mouth of a stream
delta
What are 2 approaches to water conservation
Water can be conserved by individuals limiting water use and by governments enforcing conservation laws and antipollution laws.
What are the parts of a river system
A river system consists of a main stream and tributaries.
What is a disadvantage of living on a floodplain
flooding
a process of removing salt from ocean water
desalination
an area along a river that forms from sediments deposited when the river overflows its banks
floodplain
The change of water vapor into liquid water is called
condensation
What are the factors that affect the erosive ability of a river
The erosive ability of a river is affected by stream load, stream discharge, and stream gradient.
What are 3 methods for flood control
Three methods of flood control include forest and soil conservation, dams, and artificial levees.
stream that flows into a lake or into a larger stream
tributary
the change of state from a gas to a liquid
condensation
In a water budget, the income is precipitation and the expense is
evapotranspiration and runoff
How do erosive factors affect the development of a river channel
Erosive factors, such as gradient and discharge, can affect the development of a river channel, forming meanders and braided streams.
Why would forest fires increase the chance of flooding?
It burns away natural flooding prevention such as vegetation
the area of land that is drained by a river system
watershed
the volume of water that flows within a given time
discharge
any form of water that falls to Earth’s surface from the clouds
precipitation
Tributaries branch out and lengthen as a river system develops by
headwater erosion
Describe the life cycle of a lake
Over time, a lake may lose its water or fill with sediment and become dry land.
