Where do most volcanoes occur?
subduction zones
Define viscosity:
resistance to flow
What type of magma causes explosive eruptions?
rhyolitic
Things that affect viscosity
silica content, gas content, temperature
What were the biggest, baddest volcanoes?
Krakatoa &
Tambora - most explosive
VEI stands for
Volcanic Explosivity Index
What is the least dangerous type of flow?
Lava flow
Example of subduction zones
Cascade Range
Andes
Example of divergent zone
Mid-Atlantic Ridge
Example of a hot spot
Hawaiian Islands or
Yellowstone
3 magma types
Basaltic, Rhyolitic, Andesitic
Basaltic magma
forms shield volcanoes
Rhyolitic magma
forms calderas and are EXPLOSIVE
Andesitic magma
forms steep sided strato volcanoes
3 types of stuff ejected from volcanoes
lava flows, pyroclastic, gases,
What is her dog's name?
Cleo
Music she likes?
Metallica and Old Crow Med Show
What were the type of floods we studied?
River Floods
What is a factor NOT contributing to the occurrence and severity of floods?
Fish populations
The formula T=(N+1)/M is used to calculate what?
Recurrence Interval
True
the idea of floodplain management is based on the recognition of flood hazards and using that info when planning for land usage
Q=AV
discharge = area * velocity
Name two factors that greatly influence mass wasting:
Moisture
Gravity
Define Angle of Repose:
the critical angle above which failure occurs (approx. 30-35 degrees for loose dry stuff)
Classification of mass movement is based on what?
Type of material/type of movement
The slowest type of movement is a:
creep
True
The Gros Ventre Slide in Wyoming occurred because there was over-saturation of the rock layers and the river at the base of the mountain had cut down into the slope, thus destabilizing it
Why does East TN have so many landslides?
due to mountains and moisture
bigger mass =
bigger critical angle
2 types of energy
nonrenewable and renewable
Examples of renewable energy
water, wind, solar, geothermal, biomass
Examples of non-renewable energy
coal, oil, natural gas
Types of energies
Thermal, kinetic, potential, chemical, electrical, nuclear
What type of non-renewable energy has risen the most in price?
Natural gas
Examples of Biomass
corn, wood, peat
Why don't we use solar and wind energy in the US?
It's not reliable and there's no place to store the energy
Define energy efficiency:
the ability to use less energy and provide some level of service
Define Porocity:
how able something is to absorb fluids
permeability
how well the pores are connected in a rock
Hydraulic conductivity
how well a material can flow (like water)
Darcy's Law
q = (K(h1-h2)) / (d)
Hydro Cycle
Precipitation, Infiltration and Runoff, Groundwater flow, Transpiration, evaporation
