plates
gigantic slabs of rock that make up the earth's crust
fault
a break or crack in the earth's crust where plates come together
weathering
the slow process that breaks rocks down into smaller pieces
deposition
the dropping off of weathered rock
composite volcano
cone shaped volcano with explosive and gentle eruptions
shield volcano
wide flat volcano formed by layers and layers of lava building up over time
cinder-cone volcano
a volcano with steep sides that forms when pieces of lava fall around the vent
hot spot
place where magma partially melts through the earth's crust
creep
slow movement along the faults
tsunami
giant ocean wave caused by an underwater earthquake
erosion
movement of sediments and soil by wind, water, ice, and gravity
constructive
processs that create landform
destructive
processes that destroy landforms
landslides
mass movements of land due to gravity
avalanche
mass movents of snow due to gravity
earthquakes
vibrations on earthy's surface caused by sudden movements in earth, often along a fault
floods
excessive amount of water covering what usually is dry land
Tornado Alley
an area in the plains where tornadoes are highly likely to occur
physical weathering
rocks broken down into smaller pieces without changing the rock type
chemical weathering
when the minerals in the rocks change into other minerals....lichens
reverse fault
plates pushed together by rocks moving up example Himalaya mountains
strike slip fault
plates moving along side each other,not up or down. example San Andreas
tornado
a narrow column of wind
dormant volcano
volcano that isn't erupting anymore
normal fault
plates pull apart and the rocks above the surface move down
Ring of Fire
location in the Pacific Ocean where a bunch of volcanoes can be found
creep
slow movement of land along the faults
magma
melted rock beneath the earth's surface
lava
melted rock that reaches the earth's surface
rift volcano
volcano found along the edge of spreading plates
active volcano
a volcano that is still erupting
