Q

Alfred Wagner is credited for what hypothesis?

A
Continental drift (not a real thing)
Believed there was one super continent PANGEA
16
Q

What was wegners evidence for continental drift?

A

Fit of continents

Fossil evidence

Ancient paleo climates

Correlation of rock structures

17
Q

What is curie point?

A

The temperature at which a rock becomes magnetized

18
Q

List the stages for plume arrivals

These are for MOR

A

Stage 1 doming
Stage 2 rifting above dome and basalt volcanism
Stage 3 creation of small linear sea
Stage 4 creation of MOR

19
Q

List three variations of convergent boundaries

A

1) oceanic- oceanic ex Japan, island arcs, Indonesia, Philippines
2) oceanic- continental ex Andes mtns, cascade mtns volcanic arcs
3) continental-continental ex Himalayan and Appalachian and alps

20
Q

What is atmospheric heating?

A

A fundament principle where sun rays that are closer to the poles are oblique Rays (not direct) and the equator get direct sun light

21
Q

Coriolis effect is

A

Tend to bend to the right on norther hemisphere and left in the Southern Hemisphere

22
Q

Global wind patterns

A

Air rises it expands and cools producing overcast and rainy conditions

Air descends it compresses and warms producing clear skies and dry conditions

23
Q

Name the cells of convention

A

Hadley
Ferrel
Polar

24
Doldrums is
``` Low pressure belt (around the equator) No air (dead) ```
25
Horse latitude is
No wind belt with high pressure | There are two 30 degrees from equator
26
Air masses
cP- cold and dry mP- cold and wet cT- hot and dry mT- hot wet
27
Jet stream
High (30k-40k) fast moving air
28
Me the types of weather fronts
Cold fronts Warm Occluded fronts
29
Name the stages of the evolution of a thunderstorm
Early stage- clouds build, actively rising cumulus cloud (no rain) Mature stage- it has both updraft and downdraft. Moisture becomes heavy and falls (heavy precipitation) Dissipating stage- end of storm light rain falls (downdraft)
30
Ingredients for a tornado
cP air mT air Jet stream They developed from supercell storms
31
Equivalent storms to hurricanes
Typhoons- western pacific | Cyclones- Indian oceans
32
Evolution of storms starts with
Tropical depressions 23 mph Tropical storms 40 mph Hurricane 74 mph
33
Hurricanes are low pressure systems | That rotate
Counter clockwise in northern hemisphere | Clockwise in souther hemisphere
34
Eye Of the storm is
Hi pressure
35
Hurricanes cause damage from
Wind damage Flooding Storm surge
