Hi guys,
-
Not Synced
the objective of this video is to look at
-
Not Synced
the bedding structures that form
when sediment is deposited.
-
Not Synced
These bedding structures all form
in different environments.
-
Not Synced
These environments which create the bedding
structures will be discussed.
-
Not Synced
Firstly,
we will talk about the horizontal beds,
-
Not Synced
or strata,
that the sediment is laid down in.
-
Not Synced
Sedimentary rock is stratafied,
which means that it has layers.
-
Not Synced
These layers have formed because sediment
is laid down in horizontal layers called strata.
-
Not Synced
Between each layer of strata,
we have bedding planes.
-
Not Synced
And these bedding planes form because
the region has experienced
-
Not Synced
a change in depositional environment or material.
-
Not Synced
We can see here in this photo that we have
had one type of sediment laid down
-
Not Synced
And then,
a change in depositional environment
-
Not Synced
has caused a different type of sediment
to be laid down on top,
-
Not Synced
in between which is a bedding plane.
-
Not Synced
We know that the strata towards
the bottom of a series is older
-
Not Synced
than the strata at the top.
-
Not Synced
And this happens because the sediment
is laid in this way.
-
Not Synced
Bedforms are formations that occur due to
the movement of wind and water.
-
Not Synced
Bedforms are created when water or wind,
flows over loose sediment.
