GEOLOGY & PLATE TECTONICS
24
geology:the study of the earth and the forces that change the shape of the earth
sonar:the device that Harry Hess used to map the ocean floor
mantle:convection currents take place in this layer of the earth
pangea:the great landmass that was once all connected was called_________
convergent:this boundary comes together to create mountains, hills, trenches, etc...
divergent:this boundary divides and forms valleys, ridges, and results in sea-floor spreading
transform:this boundary slides side to side and creates earthquakes
subduction:the oceanic crust slides under the continental crust
continental:this crust is made up of a type of rock called granite
oceanic:this crust is made up of a type of rock called basalt
ridge:a chain of under-water mountains formed form sea-floor spreading
rift zone:a large valley shaped are where the plates of the crust are moving away from each other forming a system of cracks in the crust
underwater mountain ranges:result of sea-floor spreading
seafloor spreading:the sea-floor is pulling apart at the ridge
ring of fire:an area of many volcanoes that are formed on the edge of continents and island in the pacific ocean
Nicholas Steno:a geologist who studied the layers of rock and found fossils in the layers
strata:another word for rock layers
James Hutton:known as the founder of modern geology
Alfred Wegener:created a theory that the continents were one connected
Harry Hess:geologist who mapped the sea-floor during World War 2
crust:the top layer of the earth
core:the hottest layer of the earth
tectonic plates:a theory that a geologist developed that the continents were once connected but then drifted apart
theory:a well researched idea that has a substantial amount of evidence to prove it correct or incorrect
