Fak bod radiation o earth versus other gaa.ies'

What is blackbody radiation? Draw blackbody radiation curves for the universe and forEarth

and explain the significance of each for topics covered in this course.

Colder- longer wavelength

Earth technically warmer than its black body radiation

ignificant for measuring temp of different planets! and proof for "ig "ang #how? $sk%angmuir?&

tudy diagrams and figures'

-be able to interpret figures and understand its significance #example- black body as proof

for "ig "ang&

(adioactive Decay)

+raph of isochron

,infinity isochron becomes vertical line from starting point up, line is hori/ontal because slope is /ero #e0lamda#t&-1&

$t tinfinity no more (b 23 left because it decays

Calcium feldspar- high strontium

6otassium feldspar- high rubidium

"7, mineral does not care whether something is trontium 23 or 28$t t only strontium on graph #this is starting point9no rubidium&

-:nly use billion-year half-life radioactive isotopes to measure age of earth

$fter about ten half-lives you have 1;1! ratio so you end up with hardly any pairing#so there is almost nothing left of original&

Ways of measuring age that do not include isotopes)6rinciple of uniformitarianism #processes happening now also happened in the past&

6rinciple of hori/ontality) sediment when it first falls will fall hori/ontally #good for

telling relative age of sediments- one on bottom older! one on top younger&

Extinct radionuclides

-time between chondrules and minerals is small so you need system with short half-life!

so need different methods besides isochrones

$t tinfinity

ust before solar system formation #because you had to have $l-=8 present

6age 18

$lso shows extinct nuclides were present in early planets$lso meteorites must have formed very rapidly after the super nova #because they

brought $l=8 to our Chondrites&

$lso know earth is chondritic so we know ratio of elements:cean ridges--- volcanism that results from mantle melting! know that ocean rigsB

igneous rocks have to have been part of the mantle

Core Composition) ave no samples. Chondritic comp of dense elements! so we know

core is prob. mostly iron.
