0 s5 ` Y. O3 i: c' [7 vI'm glad you brought up the question of our investigation into makeup of Earth's interior,In fact since this is the topic of your reading assignment for next time. Let me spend there last few minutes class taking about it .There were sveral8 s+ k2 A# r- f e4 o
important discoveries in the
early part of
this century and
helped geologists develop more
accurate picture in the Earth's interor
' ^) p, q+ M0 {. \" Q% c athe first
key discovery had to do
seismic wave -----
remember they are the viboration cause by earthquakes,Well,scienist found that they traveled thousands of miles through the Earth's interior.this finding enable geologists to study
inner part of earth, you
see ,there studies
revealed that these
viboration were of two
types.
compression ----or
P----wave and
shear----or S ---wave and reseachers found that P waves travel through both
liquid and solid.while S waves travel only through
solid matter
. Q2 `1 c6 Q; l# hin 1906 a
british geologist discovered that
P waves slowed down at a
certain depth kept traveling deeper.on the other hand S waves either disappeared or were
reflected back,so he conclude that
depth marked the boundary between a
solid mantle and liquid core.thress years later another boundary was discovered---and between
the mantle and the earth's crust
" j; o2 |; w9 {9 x8 t9 W* Cthere's still a lot of be learned about the earth ,
for instance.geologists kown that
the core is hot ,
evidence of this is
the molten lava that flow out of vocanoes.but we're still not sure
what the source of the heat is . t8 \+ L: k" U7 S7 J: q# Z# U- ]6 Q2 h
