Physical Geography Flashcards
7 continents
Asia, Europe, Africa, Antarctica, austrailia, North America, South America
5 oceans
southern, Arctic, indian, pacific, atlantic
oceans
body of water surrounding land
seas
body of water partially enclosed by land
lake
body of water completely enclosed by land
Earth’s layers
core, mantle, crust
Plate
floats on the crust
Subduction
oceanic plate(heavier), goes under continental(lighter) and melts and comes back up Makes volcanoes
accretion
occurs during subduction as oceanic plate goes under continental the debri heats and the plates become one big plate
Fold
when rock gets hot and makes a formation
fault
where 2 tectonic plates come together and there is a crack and lots of earthquakes and tsunamis
ring of fire
area around pacific rimthat has a lot of earthquakes and tsu;nanmis
glaciers
frozen rivers valleys are U shaped
Morraine
debris left by glaciers
climat
long trerm atmospheric conditions
weather
short term atmosphereic condiations
tilt
what causes season and the wqay the ligjt fall
equinoz
when day and night are equal
solstice
either day or night is longer than the other
wind patterns
heating and cooling of air
prevailing winds
consistent wind patterns
coriolis eggect
N winds are clockwise and s are counterclockwise
wind pattern names
westerlies, trades, doldrums, and horse latitude
ocean currents affect of climat
warm or cool the land
El Nino
when currents change direction in pacific rim
rainshadow effect
where land becomes desert because mountains are blocking all plant growth and rainy weather
torpical climate
found along equator wet or dry
tropical wet
daily rain found inasia africa and SA lts of wildlife
tropical dry
wet and dry season few plants and short grass in africa asia austrailia and C and SA
dry
has deserts and steppes
deserts
little plant ife 10 inches of rain per year
steppes
treeless grassland transition zone 10-20 in of rain per year
midlatritude
4 subregions Marine west coast, mediterranean, humid subtropical, humid continental
marine west coast
ocean winds coniferous and deciduous cool summers cool damp winters
mediterranean
wood bushes and short trewes mild rainy winter hot sunny summers
humid subtropical
prairies evergreen deciduous short winters rain all year
humid conatinental
evergreen in N no ocean winds snowy winters
High latitude
three regions sub arctic tundra and ice cap
sub arctic
perma frost short cool summers evergreens
tundra
dark winters lichen moss hsort grass cold summers
ice cap
snow and ice upo to 2 mi thick lichen only
canal
man-made waterway constructed to allow the passage of boats or to carry water
isthmus
narrow strip of land connecting two larger land masses
butte
isolate hill with steep sides and a flat top
mesa
isolated flat topped elevationthat rises abruptly formt he surroundign area
sea
large body of water partiall enclosed by land
geyser
spring that throws forth jets of hot water and steam
oasis
fertile area with water in the middle of a desert
gulf
part of an ocean or sea extending into the land
cape
large point of land extending into the water ususally at an abrupt angle
lagoon
shallow body of water protected form the sea by snad bar or reefs
fjord
long narrow inlet of the sea between hih cliffs
delta
flat area of sediment deposited a thee mouth of a river
prairie
large area of flat greaasssland
plain
large area of flat land
peninsula
area of land nearly surrounded by water
island
area of land surrounded by water
reef
ridge of rock coral or sand just above or below the surface of the sea
