100
a large piece of rock that has become detached from a cliff or mountain; a boulder?
What is a rock?
100
rigid lithospheric plates that move slowly over the underlying mantle.
What are plate techtonics?
100
FAULT LINES
What is THE PLACE THAT EARTHQUAKES FORM
100
a vent for magma from a volcano
what is a volcano?
100
crust, mantle, outter core,& inner core
what are the 4 layers of the earth
200
lithosphere
What is the layer that the plate tectonics float on
200
WHERE IS THE MAIN FAULT LINE TH TENNESSEE
Mimphes
200
colliding tectonic plates
how do volcanoes form?
300
intrusive : forms inside the earth, slow cooling, and has large crystals extrusive: forms at or near the surface, fast cooling, has little or no crystals
What are the two types of igneous rocks? where do they form?
300
the pangea theory
What is the idea that all the continents were all together?
300
An earthquake is caused by what?
What is the idea that all the continents were all together?
300
the ring of fire
where do most of the volcanoes form
300
5 to 100 kilometers
how deep is the crust?
400
silicate and non-silicate silicate
What are the two types of mineral? which one makes up 90%of the earth?
400
why was the pangea theory cheated
techtonics plates
400
lithosphere
Where do plate tectonics float?
400
magma, being less dense than the rock surrounding it, tries to float to the surface
why do volcanoes erupt?
400
the crust
which is thinner the crust or the inner core
500
Sedimentary Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Metamorphic Metamorphic rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing) Igneous Igneous rocks are formed when magma (molten rock deep within the earth) cools and hardens.
What are the three types of rocks, and what are they made of
500
TECHTONIC PLATES
why do scientists believe that California will one day separate from the U.S.A?
500
where is the a major fault line in the U.S.A
California
500
Mt. St Helens
what is the volcano that erupted in 2009 when no one thought it would?
500
crust: silica oxygen, and aluminum mantle: magnesium silica oxygen & aluminum inner core: iron &nickel outter core: iron & nickel
What is the what is the chemical make up of all four layers ?
