I'm standing in the stream that's
flowing into Moss Beach on the coast of
California
this stream would normally be quite
small but its rained here a lot recently
the water is really flowing fiercely
from the land into the Pacific Ocean
you may be able to see that this stream
is kind of brown from the mud that's
being carried from the land where small
particles have been weathered from the
rocks and it's being carried out into
the ocean some of it might be deposited
miles from here but some of the bigger
grains will be deposited right close to
shore after the water energy is low
enough that it can't carry these larger
grains anymore
the rock record is in part a result of
processes like this moving sediment from
the shore out into the ocean where it
gets deposited forming layer after layer
preserving with it much of what we know
about the history of the earth
