Chapter 11 questions Flashcards
Which layer of the earth surrounds the core and is primarily composed of solid rock
Mantel
Which layer of the earth is the outermost and thinnest zone of the earth that lies under the continents and ocean
Crust
Which layer of the atmosphere is the layer of rock within the mantel who’s convection currents causes plate movement
Asthenosphere
What is the order of earths layers (inside to out)
core
mantel
asthenosphere
lithosphere
crust
IDK
The North America and Eurasian plates are moving apart from one another and creating the Mid-Atlantic ridge. This is an example of which plate boundary
Divergent- such as between the African and Arabian plates
Tectonic plates move slowly across the asthenosphere on
convection currents as a result of differences in density
Convergent boundaries between 2 continental plates produce
mountain ranges
the weathering of rocks from wind, water, and thermal expansion is known as
physical weathering
which rock forms when pre-existing rock is subjected to high temperatures, pressure, or chemicals
metamorphic rocks
which rock forms when existing rock is weathered and deposited as small grains
sedimentary rocks
which rock forms when magma cools and hardens
igneous rocks
what are oil shale rocks
sedimentary rocks, releases a liquid known as shale oil
what is leachate
the solution that forms when liquid travels through solids and removes some components
strip mining has all of the following harmful environmental effects EXCEPT
A. regrowth of vegetation where strip mining has occurred is very fast
B. toxic substances are left behind
C. biodiversity is destroyed in the area
D. Streams around the area become polluted
E. air pollution around the area occurs
A. regrowth of vegetation where strip mining has occurred is very fast
The vibration created when rock fractures beneath the earths surface is a
seismic wave
Finding substitutes for mineral resources will
help to keep supplies of resources sustainable
when rock ore contains small concentrations of gold, which technique is used to increase the amount of gold retrieved
Cyanide leaching of crushed rock
what occurs when a mineral resource becomes scarce
price increases, which can encourage use of substitutes and resource conservation
what refers to the process in which rainwater moves through underground mines and tailings and carries H2SO4 into water bodies
Acid mine drainage
One big environmental problem with smelting is
air pollution because smelting releases sulfur dioxide and particulates
When a mineral resource is too deep to be surface mined, which technique is used
Placer mining, because it is safer and easier to remove the minerals from spring water that flows up from deep underground
Which of the following is the LEAST sustainable use of nonrenewable mineral resources
A.recycling all aluminum resources
B. reducing dependency on metal resources by using alternatives
C. increasing subsides for mining companies to lower prices for consumers
D. using the water of mineral-based operations as raw materials in other industries
E. upgrading current mineral manufacturing plants to reduce pollution and waste
C. increasing subsides for mining companies to lower prices for consumers
