Layers
thin rocky outer layer of earth
crust
large natural elevation of the earth's surface; a large steep hill
mountains
small pieces of rock
sediments
the vibrations from earthquakes that travels through the earth
seismic waves
large amount of mud mixed with water that slides down a mountain due to gravity, causes damage and destruction
mudslides
the layer below the crust, the largest layer of earth
mantle
a large natural stream of water flowing in a channel to the sea, lake, or other such stream
rivers
remains of once-living animals or plants in rocks
fossils
body waves, p waves, and s waves
types of seismic waves
slowly moving massive ice formed by snow
glaciers
a ball of very hot metals, liquid
outer core
a mound or ridge of sand or other loose sediment formed by wind
dunes
formed when sediments are cemented together
sedimentary rock
seismic waves that travel along earths outer layer
surface waves
caused by rainwater reacting with the mineral grains in rocks to form new minerals
chemical weathering
compressed into solid state
inner core
the outline of a coast especially in regard to its shape and apperance
coast lines
formed when magma or lava cools and hardens
igneous rocks
p waves
pieces of earth broken down from weathering, they move from one place to another
erosion
rigid outer layer of earth, includes crust and upper mantle
lithosphere
a broad area of relatively flat land, major landform
changed by heat, pressure, chemical action
metamorphic rocks
second wave you feel in an earth quake, slower than a p wave. can only move through solid rock
s wave
after pieces of earth are carried by erosion they are deposited somewhere else
deposition
