what are the threetypes of plate boundaries and an example of each? |
Transform….earthquake,
divergent…. mountains, and convergent…. Volcano |
|
|
what is pangea? |
name ofwegeners super continent….
Contained all land masses…. 200 million years agopangea started to break apart. |
|
|
What was the continental drift and who created this theory? |
proposedthat continents are not stationary but have moved around in the pas....

|
What are the 6 major facts of climate control? |
- solarenergy
- latitude - differentialheating of land and water - globalpressure systems - globalwind patterns - topography |
|
|
explain solar energy |
- mostimportant factor, has to do with the greenhouse effect, incoming solarradiation is known as isolation |
|
|
explain latitude |
- angle ofsuns rays affects intensity of solar energy (heat) |
|
|
explaindifferentialheating of land and water |
impact on continentality and maritime climates |
|
|
explain global pressures system |
created by uneven heating of oceans andcontinents, and it influences winds and storms |
|
|
explain global wind patterns |
winds flow away from high pressure toward lowpressure
|
|
|
explain topography |
adiabatic lapse, orographic effect, rain shadow
|
|
|
what is the differencebetween climate and weather |
Weather is what conditions of the atmosphere areover a short period of time, and climate is how the atmosphere"behaves" over relatively long periods of time.
|
|
|
What is climate change? |
cycles of advance and retreat,interglacials- warm intervals between ice ages
|
|
|
What are the two greenhouse gases? |
Carbon Dioxide (co2) and methane (ch4)
|
|
|
What is good news about greenhouse gases? and why are these good things happening? |
Good news is co2 levels aredeclining in the u.s.
co2 emissions have fallen 12% in thepast 5 years because: - transitionfrom coal to natural gas for electricity - peopleare driving and flying less - morefuel efficient cars -therecession |
|
|
Water stress is a major concern. List the three areas of concern and give an example for each. |
- scarcity-only 3% of worlds water if freshwater
- sanitation-only 3% of worlds water if freshwater - access-70% of freshwater is locked up in ice caps and glaciers |
|
|
What is topography and each of its meanings. |
adiabaticlaps- rate of cooling with increasing altitude
orographiceffect- impact of mountains on precipitation/ wet winward side rainshadow- dry area on leeward side |
|
|
explain the territorial limits/ resource zone:
|
- EEZ's-exclusive economic zones- grants rights to resources 200 nautical miles fromcoastline
- LOS- lawof the sea- countries can claim resources beyond EEZ limits if theircontinental shelf extends beyond 200- mile limit - geopoliticalissues |
|
|
Definition of Globalwind patterns-and list the Hadley cells and climate pyramid
|
- Windsflow away from high pressure toward low pressure
---Sub polarlow ---subtropicalhigh ---inter tropicalconvergence zone ---Subtropicalhigh ---Sub polarlow |
|
|
What are bio- regions? |
- includeplants and animals of a distinct region
- influencedby climate types |
|
|
What are climate regions? |
- based onlong- temp. averages (30 years) of temperature, precipitation, and seasonalitydata
- climographs-show monthly temperature and precipitation averages |
|
|
what percent in the world is urbanization? |
54% |
