12.1 Earth Processes Shape Our Resources
The supercontinent from 200 million years ago:
What is Pangea?
The three major rock formations
What is sedimentary, metamorphic, igneous?
The major side effects to strip mining:
What is as material is placed back on the top layer, the lack of topsoil means very slow re-vegetation?
When movement along faults occur gradually and smoothtly:
What is creep?
What are tectonic plates and how does their movement shape our world?
Tectonic plates are what the Earth's crust is divided into and the movement of these pieces of crust create the continents as well as mountain ranges.
What is a hot spot?
Economic mineralogy:
What is the study of resources that are valuable for manufacturing and trade?
Ways that metals can be recycled:
What are old cars and aluminum cans?
Where the largest earthquake in North America, a magnitude 8.8, struck in 1812:
What is New Madrid, Missouri?
Where and why do volcanoes and earthquakes occur?
Volcanoes and earthquakes occur around the boundaries of tectonic plates due to the tension between the plates and the magma between.
What is mid-oceanic ridge?
The metals consumed in the greatest quantity
What are iron, aluminum, manganese, copper and chromium?
New materials that can replace mined ones:
What are polymers, ceramics, plastics, alloys?
A flood that is expected to occur once in every ten years
What is a “ten-year-flood”?
What are some of the environmental and social costs of mining and oil- and gas-drilling?
The difference between a period and an era:
Three ways the Earth provides energy:
What are oil, coal, and natural gas?
Conserving our mined resources means:
What is to extend our supply of minerals and reduce the effects of mining them?
Level expenses that are periodically inundated/overflowed:
What are floodplains?
How can we reduce our consumption of geologic resources?
We can use polymers, alloys, plastics, and ceramics.
The Case Study connects since:
What is demonstrating the tensions between natural resources and mining in a real-life scenario?
The stages of the rock cycle
What is weathering, erosion, deposition, compaction and cementation, heat and pressure, melting, cooling, repeat?
FEMA estimates that due to rising sea levels caused by global warming, 25% of all coastal homes in the US could have the ground washed out from under them by:
What is 2060?
Explain why floods and mass wasting are problems.
These issues affect human populations, which make them the worst and most feared of the disasters that befall humans.
