Rock Cycle
What are the 3 types of rocks?
Igneous, metamorphic, and sedimentary
process in which sediment is laid down in new locations
deposition
the theory that changes in the earth's crust during geological history have resulted from the action of continuous and uniform processes.
Uniformitarianism
The solid part of the earth made mostly of iron and nickel
inner core
A rigid layer made up of the uppermost part of the mantle and the crust.
lithosphere
How does and igneous rock turn to a metamorphic rock?
Heat and pressure
processes by which rock, sand, and soil are broken down and carried away
The 3 types of boundaries
Transform, convergent, divergent
the liquid layer of earth made of iron and nickel
outer core
The soft layer of the mantle on which the tectonic plates move
asthenosphere
matter that settles to the bottom of a liquid
sediment
a wind-formed deposit made of fine particles of clay and silt
Loess
What boundary creates an earthquake?
transform boundary
in between the crust and outer core
mantle
what moves the tectonic plates
convection current
the process in which rock is broken down by changes in its chemical makeup
chemical weathering
a naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition
mineral
What boundary creates mid-ocean ridges?
Divergent boundaries
the layer of earth that we live on
crust
move towards each other
convergent
reduces solid rock to smaller fragments but does not alter the chemical composition of the rocks and minerals
mechanical weathering
the series of processes that change one type of rock into another type of rock
rock cycle
What boundary creates mountains and volcanoes?
Convergent boundary
the strong, lower part of the mantle between the asthenosphere and the outer core.
mesosphere
moves away from each other
divergent
