a mountain made mostly of rock layers

a mountain made by huge tilted blocks

the breaking down of rocks into smaller pieces

the picking up and  removal of rock particles

weathered rock, decayed plants and animal matter,living things, air, and water

materiel in soil formed by the breakdown of plant and animal materiel

any of the layers of soil from the surface to bedrock

water that soaks into soil and rock by collecting in spaces

the downhill movement of Earth's materiel caused by gravity

the dropping of of sediments

a huge sheet of ice and snow

a jumble of many sizes of sediment,deposited by a glacier when it melts

a deposit of many sizes of sediments

a natural occurring solid in earths crust with a definite structure

a rock that forms when hot, liquid lava cools and hardens

a rock that forms from pieces of other rocks

changed  as when one kind of rock is turned into a rock with different properties

rock continually changing from one kind to another

the idea that in a series of rock layers,the bottom is the oldest and the top is the youngest 

the age of a rock as compared with another rock

a listing of earths rock layers in order from youngest to oldest

tiny remains,trace,or imprint of living things imprinted in earths crust

remains of living things that were widespread but only for a short time

the time it takes for half the elements to change or decay into a new element

rocks age in years

long period of time in Earth's history
