rock layers folded by being squeezed together

mountain made by huge tilted blocks 

the breaking down of rocks into smaller peices

the picking up and removal of rock particals

mixture of weathered rock,and decayed plant and animal matter

soil formed by the breakdown of plant and animal material

the layers of soil from the surface to the bedrock below

water that soaks into the soil and rock

the downhill movement of earth material caused by gravity

the dropping off of sediment

a huge sheet of ice and snow that moves over land

jumble of many sizes of sediment deposited by glaciers

deposit of many sizes of sediment in front of the sides of glacier

naturally occurring solid in earths crust 

a rock that forms when hot

a rock that forms from pieces of rock that are squeezed 

rock continually changing from one kind into another in never ending process

a rock that forms from another kind of rock 

idea that in a series of rock layers

the age of a rock as compared with another rock

listing rock layers in order from oldest to youngest

any trace,imprint or remains of living thing preserved in earths crust

remains of a living thing that was widespread 

time it takes for half the mass of radioactive element

age of a rock in years

one of the four long stretches of time in history
