100
name the 3 types of volcanoes
composite, shield, cinder
100
define erosion
slowly being worn down by the elements
100
volcanoes and _____________ occur at the boundary's of tectonic plates
earthquakes
200
compare and contrast the differences between convection and conduction
convection is heating through movement of mass while conduction is heating through direct contact with some thing
200
list all of earths physical layers in order
crust, mantel, inner core, outer core
200
where do volcanoes usually form
on the edges of tectonic plates
200
define deposition
when an object is put down in a new spot from whichnit was put up
200
what is the epicenter of an earthquake
the area directly above where the earthquake actually started along the fault line.

the inner core
300
what volcanoes are the Hawaiian islands made up of
shield volcanoes
300
is erosion more like a hammer hitting a rock or slowly sweeping said rock till its thin bare
sweeping

describe the three tectonic plate boundary's and what they do
divergent boundary-moves away from another plate convergent boundary-hits another plate or runs into it transform boundary-when two plates rub together
500
what is the mantel consisted of
hot liquid rock that floats around
500
what do the 3 types of volcanoes look like. describe it
shield-wide, gently sloping sides, medium eruptions cinder-small, made of volcano cinders, crater in middle where eruption occurs composition-tall, steep sloops, most powerful eruptions
500
how are erosion and deposition DIFFERENT
weathering is immediately breaking of a rock while erosion slowly where's away at the surface of the rock
500
which of earths layers contains the most iron
inner core
