- anceint fossils
- one peice of evidince tht proves tht the continents once were combined? 1.
- 33%
- how much % dose the core take up?
- continental continental
- 2 plates colide 2 make mts?
- aqatic reptiles and plants
- one peice of evidince tht proves tht the continents once were combined? 2.
- mars
- wht planet is simalar to the earths core?
- outer core
- the _____ is the liquid layer of the earths core?
- oceanic continental
- subduction zone --> <--
- lithoshere
- the outher most rigid layer of the earth is called the __________?
- tectonic plates
- individual sections of the lithosphere of the earth. They fit together in a way similar to a jigsaw puzzle, but are always moving very slowly, floating on the molten rock of the lower mantle.
- folding
- the bending of rock layers due to stress
- mountian formations
- one peice of evidince tht proves tht the continents once were combined? 4.
- sulfer and oxygen
- wht else is the core contain?
- volcanic mts
- convergent boundrays molton rock erupts?
- ridge push
- the prosses where it slides down the lithoshere - astenoshere boundry?
- uplifting
- moving up? formation of mts rebounding of the crust when the weight is removed v ^ v
- oceanic oceanic
- island arcs plates subdivide?
- granite
- wht is the continental crust simalr to?
- iron
- wht is the core mostly made out of?
- sea floor spreading
- the theory that states that the sea floor moves apart and then at mid ocean ridges and causes continents to move, is evidence for continental drif
- megnetic poles
- wht reversed themselves through out history? (was the main evidence tht the sea floor was spreding?
- continental oceanic
- the two types of crust ______ and _______?
- footwall
- below?
- deformation
- when rock changes its shape due to stress?
- faults
- a break in a body of a rock along which one block slides relitive to another?
- theroy of plate tectonics
- states tht the earths's lithoshere is divided into plate tectonics?
- strike slip
- occuts when opposing forces cause rock to break and move horazontally?
- aciticline
- rocks fold upward? ^ ^ ^ mts?
- cynclines
- rocks fold downword? v v v
- subsitance
- the sinking of regions of the earths crust to lower elevations? occurs where the lithoshere is cooler and more dense? occurs on the ocean floor lithosheric plates become streached at rift zones
- alfred wegner
- in the 1900's propsed a theroy tht the continents were once together and have drifted apart?
- hanging wall
- above?
- sizemologist
- who is a person tht studies sizemic waves?
- mid ocean ridges
- a chain of of mts beneth the oceans are called?
- mantle
- wht layer contains most of the earths crust?
- ocean floor
- where do scientists look for the mantal?
- reverse
- causes the hanging wall to move up relitive to the foot wall ( occurs at convergent boundrays? tectonic forces push the rock difference is based on the position of the rocks)?
- ancient glaciers
- one peice of evidince tht proves tht the continents once were combined? 3.
- convergent boundray
- the boundray formed by collision?
- divergent boundary
- tectonic plates tht are mobing away from each other? <-- --> ?occurs mid ocean ridges?
- crust
- wht is the thinest layer of the earth?
- compression
- stress tht occurs when forces act to squezzw on an object?
- monocline
- rock layers are folded so tht both ebds are horazontal caused by verticals?
- core
- inner most layer of the earth?
- fault blocks
- blocks of crust on each side of the fault?
- tension
- stress tht occurs when forces act to strech an object?
- denser
- the ocanic crust is ______ then then continental crust?
- basalt
- wht is the oceanic crust compisition simalr to?
- inner core
- the _____ is the solid dense center of our planet?
- composition and physical
- the earth's interior is made up of different layers each ering in _____ and _______ property?
- mesoshere
- the strong lower part of the mantle is called the ____?
- coal and salt deposits
- one peice of evidince tht proves tht the continents once were combined? 5.
- astenoshere
- the _______ is a soft layer of the mantle on pieces of the lithoshere moves?
- core
- wht is bigger the earths core or mars?
- pangea
- wht was the name for all the continents combined?
- stress
- the anount of forse per unit area tht is put on a given material?
- continental drift
- theroy tht states tht continents once formed a single landmass broke up and drifted?
- slab pull
- the prosses where it sinks and pulls the rest of the plate w/ it?
- ????
- wht causes anticlines and cyliclines? (find out in ur notes) no folding and faults ummm guys thts all i can member from the test soo like i guess i say good luck!
- normal
- causes the hanging wall to move down relitive to the foot wall (tectonic forces pull apart?) occurs at divergent boundrys?
- transforn
- plates slide past each other san andraes fault CA? ^ v
- crust
- wht is the outer most layer of the earth?
- folded mts
- convergent boundrays anticlines and siliclines?
- fault block mts
- divergent boundrays ?
- rift zones
- tht crack between 2 plates tht are pulling away from each other?
