3-6 Flashcards
The water and human wastes that are washed down sinks toilets and showers are known as
Sewage
Water that is tired in layers of soil and rock beneath earths surface is called
Groundwater
Chemicals that kill crop destroying organisms are known as
Pesticides
Water that causes erosion picks up blank or particles of sand and rock
Sediments
About 97 percent of water on earth is
Salt water
Water that causes erosion picks up
Sediments
The water and human wastes that are washed down sink showers and toilets are called
Sewage
Chemicals that kill crop destroying organisms are called
Pesticides
Most water pollution of the result of
Human activities
Blank wastes agriculture wastes including animal wastes fertilizers and pesticides into ponds causing algae to grow
Rain washed
Wastes produced by agriculture households industry mining and other human activities can end up in
Water
Blank is stored in souk and rock beneath earths surface
Groindwater
Blank requires effective cleanup of oil and gasoline spill proper sewage treatment and reduction of pollinates
Keeping water clean
Most communities treat blank before returning it to the environment
Sewage
Where do wetlands form
They form in places where water is trapped in low areas or where groundwater seeps trough the surface
How are wetland important to migrating birds
They are home to many that are migrating during winter
Why do wetlands have a rich supply of nutrients
Dead leaves and other plants and animals materials serve as natural fertilizers
What are three common types of freshwater wetlands
Marshes
Swamps
Bogs
Describe two ways that wetlands are important to living things
Shelter
Supply nutrients
What impact has human development had on the Florida Everglades
Use for farm lands
Which of the following wetlands would have a large number of cats told and grasslike plants
Marsh
Which wetlands would have a great many tress and be in a humid climate
Swamp
Where would mangrove trees grow
Coastal wetlands
Which of te following is not an effect of human development on the Everglades
Poco sins
Some wetlands dry up during long hot summers and fill up during
Spring rain
Sometimes called the river of grads blank is a vast wetland
Florida Everglades
A poco sin is a type of
Big
A wetland that contains both fresh and salt water is called
Coastal wetland
Wetlands affect climate by making them more
Moderate
Two important roles of wetland are to control floods and act as
Natural water filters
Describe how convection transfers heat and materials in earths mantle
It causes material to rise and then sink to the mantel
What are the three types of boundaries between earths tectonic plants
Convergent
Divergent
Transform
What are convection currents in mantle responsible for reshooting earths surface
When plates seperate pass each other crash into each other
What causes earthquakes
Mantle convection
How are volcanoes formed
Subduction plates cause partial melting forming lawr the magma later rises forming volcanoes
How are ocean basins formed
When there are earthquakes and volcanic eruptions
What changes happen fast and which happe slow
Basin slow
Earthquakes fast
Earthquakes can form along blank boundaries
Transform
Convection currents in earths blank transfer heat and materials to the surface
Mantle
The crust is the blank layer of the earth
Coolest
Tectonic plates make up earths
Lithosphere
Convection currents blank move tectonic plates across earth
Slowly
Convection work because of a fluids blank changes as it’s temperature rises and falls
Density
What might be found along a divergent boundary
Volcanoes
What explains how convection currents work
As a fluids temperature increases it’s density decreases
Which of the following is not a cause of earths internal heat
Heat leftover from earths transformation
Which of the following is likely to from volcanic mountains
Molten material rises between two divergent plates
