way to collect data about the earth's interior

astronomy, drilling through the crust, Earth's delivery service, seismic data

Parts of the earth's interior

Mantle, core, crust

What is a kimberlite

Hole from the earth to the mantle- explosive, brings materials from the crust.

What is a earthquake

release of energy as 2 plates slide past each other, and go back to its original shape.

How seismographs work

measure magnitude and earthquakes

Type of seismic waves

P-wave- compressional cause the damage.

S-wave- secondary(shear)

Reflection and refraction of waves

Reflection- return of the wave off a boundary

refraction- change in direction and velocity of a wave

How to locate an epicenter?

different location centers, the waves travel at different speeds, where they match up.

Richter scale

measure amplitude (amount of energy) 1 -10

Mercelli scale

measures destruction (I-X11)

Earth's interior

Inner core- solid

outer core- liquid

Stress

Force acting a surface

Strain

Deformation resulting from stress

Types of stress

uniform- compression in all directions

Differential- compression in one direction

Types of deformation

Elastic- non permanent

Ductile- permanent (bending)

Brittle- permanent (cracking)

Factors affecting deformation

temp, confining pressure, rate of deformation, composition of rocks

How rocks react to different stresses

elastic, brittle, ductile,

How strike and dip are used to identify faults

normal and reverse/ Divergent- hanging wall moves down/ convergent- hanging wall goes up

types of folds

anticline, syncline, monocline, dome , basin

How sediment is transported by running water?

dissolved load- ions, suspended load- small particles, Bed loads- larger particle.

How alluvial fans and deltas form

Delta- slow down velocity and water flows

alluvial- forms at a base of mountain

drainage patterns

Dendritic- most popular vein like.

radical- tire, fall away from center.

Rectangular- preexisting fractures.

how a stream erodes and deposits material

oxbow lakes, cut banks- outside turn/ point bars- inside of turn.

What is a braided stream

interwoven stream channels caused by accumulation of sediments choking off the channel and the stream splitting into smaller streams.

Parts of subsurface associated with groundwater

water table, zone of aeration, zone of saturation

porosity

holes

permebility

ability to transmit water

ground water move through aquifers

transmitted through freely

influent streams/ effluent stream/ cone of depression

give up water/ gain waters/ water is drawn up into well
