Weathering & Erosion
The removal of weathered material from one location to another.
Erosion
What is mass wasting?
The downhill movement of large masses of rocks or soil because of the pull of gravity.
What are the three forms of nonrenewable fuels?
Coal, oil (petroleum), natural gas
True or False: food scraps and alcohol is an example of biomass energy
True
What percent of our blood consists of water?
83%
Sediment that is all the same size, and is has been moved a lot by wind or waves creating small, rounded pieces of sediment can be classified as: poorly sorted, moderately sorted, or well sorted sediment?
Well sorted sediment
A pile of angular rocks and sediment from a rockfall
Talus
True
What are the three non-polluting renewable resources?
Solar, wind, and water energy
Deposits of minerals that are large enough to be mined for a profit.
Ores
What is a low energy depositional environment?
Deep lakes and areas of slow-moving air or water where the sediment lands and stays in very think layers.
How do glaciers carve the surface?
Their large masses scrape away the land when the glacier moves, creating a large u-shaped valley from the removed land.
What is the process of reclamation?
How does geothermal energy generate heat to produce steam, which turns the electric turbine?
Drilling into the hot, molten core of the Earth
How can farming and agriculture affect the water quality?
Fertilizers can run off into other bodies of water, polluting the water with toxic chemicals.
How could you describe the landforms that are produced through erosion? (Two adjectives)
Jagged and tall
Which of the following comes first in glacial erosion: the outwash, the moraine, or the formation of till?
Formation of till: the till is a mixture of sediment that is deposited by a glacier.
Why does natural gas form on the layer above the crude oil formation?
The natural gas takes higher temperature and pressure to develop, which increases the movement of the particles causing a less dense gas to form.
What is the number 1 renewable energy resource used in the United States?
Biomass energy
Why is land considered a resource?
Living things need land to meet their survival needs.
How does an alluvial fan develop?
A stream empties a large mass of sediment onto flat land at the foot of a steep slope.
How much freshwater in the world is contained by the glaciers (in fractions)?
2/3 of the freshwater on Earth is contained by glaciers.
How long is it predicted that our current oil reserves will last us?
Only another 50 years
How does hydroelectric power produce energy?
The energy of the flowing water turns a turbine connected to a generator that spins to produce energy.
What is the pH of acid precipitation?
Less than 5.6
