m. explains earths topography and more

11. What is the underlying mechanism for plate techtonics? n. Convection cells in mantle

12. 5 Plate Boundaries:
o. Divergent: rifts, ridges, new oceanic crust
p. Ocean-Continent: volcanic mountain chains, trenches q. Ocean-Ocean: volcanic island arcs, trenches
r. Continent-Continent: upfolded mountains
s. Transform: strike-slip faults

13. What is a hotspot?
t. Where a plume of magma comes up and breaks the surface, spewing out lava u. Example: Hawaiian islands

15. how do oceans and continents form?
x. Oceans:
y. Continents:

16. Where do most earthquakes and volcanoes occur?
z. G

17. The two main components that affect climate
{. Temperature & precipitation

18. Rising air vs. Descending air:
|. Rising air: cools, holds less water vapor, relative humidity increases, rain increase }. Descending air: heats, holds more water vapor, relative humidity decreases, less rain

19. What is the dew point?
~. The temperature at which relative humidity (water vapor increase) becomes 100%

20. What are 3 causes of precipitation?
. Convection – when air is heated and rises
. Orographic – when air rises as it is blown up the side of a mountain . Frontal – when air rises as it is pushed up the leading edge of a cold front

21. What 3 major factors affect temperature?
. Elevation, latitude, and green house gas concentration in atmosphere

22. What causes the seasons?
. 23. 5 degree tilt and the revolution around sun, the angles it hits earth

23. What causes is to be cooler in the SW in winter and warmer in summer? . We are tilted more perpendicular to the sun in the summer

24. List the 4 major causes of deserts:
. descending air in Hadley cells
. rainshadow effect
. cold ocean offshore
. being far away from a water source

25. Name and define the levels of organization of the living world from organism through biome: . Organism (individual living things)
. Population (group of individuals of the same species occupying a given area at the same time) . Community (all populations occupying a given place)
. Ecosystem (community plus the physical environment in a given place and their interactions) . Biome (major type of ecosystem)

26. Name and define the five parts of ecosystem structure . Energy Source (usually sunlight)
. Physical Environment (non-living materials)
. Producers (organisms that make their own food)
. Consumers (organisms that eat other living things)
. Decomposers (organisms that eat waste matter and dead organisms)

27. What are the advantages and disadvantages of internalizing external costs? . Advantages: redirect economic growth in ways that consider long-term, societal impacts; paying real price lets market regulate. . Disadvantages: difficult to determine external costs; higher prices will allow competitors that don't internalize external...
