Chapters 15 and 16 Flashcards
What is stream load?
Rock and materials carried in a stream
The layer of an aquifer in which the pore space is completely filled with water is called the zone of…?
Saturation
Which of the following is a disadvantage of living in a floodplain?
Property damage
What is an early step in the formation of a lake?
Water collects in a depression
Water that contains relatively low concentrations of dissolved minerals is called…?
Soft water
All water that is lost from an area is…?
Evapotranspiration
Which of the following is not a way to ensure the water supply for the future?
Increase industrial wastewater
The aquifer zone that lies between the water table and Earths surface is called the…?
Zone of saturation
What is when water vapor changes into liquid water?
Condensation
Calcite formations standing on the floor of a cavern are called…?
Stalagmites
Rock becomes chemically weathered when…?
Carbonic acid, formed when water passes through soil, dissolves minerals in the rock
A sloping layer of permeable rock sandwiched between two layers of impermeable rock and exposed at the surface is called a(n)…?
Artesian formation
When a rivers load and discharge increase…?
It’s erosive power increases
A cone-shaped deposit of calcite on the ceiling of a cave is called a…?
Stalactite
Uncollapsed rock between sinkholes can form arches called…?
Natural bridges
A natural flow of groundwater to Earths surface is called a(n)…?
Spring
A watershed is…?
The area drained by a river system
Open spaces in rock must be connected in order for the rock to be…?
Permeable
Two land features formed by hit groundwater are…?
Geysers and hot springs
What does not affect the depth of the water table below the ground?
Pollution
What is a necessary condition for a river system to form?
Precipitation exceeds evapotranspiration
How does a rivers velocity affect its erosive ability?
Faster rivers erode the channel more quickly than slower rivers
What factors widen and deepen a river channel?
Load, discharge, gradient
A region that clearly shows the results of chemical weathering is called…?
Karst topography
How does a river form?
Precipitation exceeds Evapotranspiration, soil soaks up as much water as it can hold, excess water erodes the land, and eventually a river valley forms
What are two ways that fresh water supplies can be maintained?
Conservation and alternative methods of obtaining fresh water
Water of any form that falls to Earth is called…?
Precipitation
The area where water from the surface can move through permeable rock to reach an aquifer is called a…?
Recharge zone
What is when liquid water changes into water vapor?
Evaporation
Which of the following minerals makes rocks especially vulnerable to chemical weathering?
Calcite
What is the difference between a delta and an alluvial fan?
A delta forms in water, and an alluvial fan forms on land
Pumping water from a well causes a(n)…?
Come of depression
What is when plants and animals release water vapor into the atmosphere?
Transpiration
