Okay, so for question one, we need to label the inner core, outer core, mantle, oceanic crust, and continental crust.
00:09
And for that, we're going to look at this figure b.
00:11
So this right here, this is the inner core, and then the outer core.
00:23
And if you see on here, this area right there, that's the inner core that corresponds with this area here.
00:30
And then this here is the outer core.
00:33
That's the outer core.
00:36
Then we have the mantle, which is going to include all of this.
00:42
And that's this part right here.
00:43
That's the mantle.
00:45
And then over here, we have the oceanic crust.
00:53
And then right over here, we have the continental crust.
01:05
Oceanic crust, obviously, beneath the oceans, and the continental crust is the land masses.
01:15
That's number one.
01:16
Number two, we need to label the lithosphere, asthenosphere, convection currents, and the parts of the mantle.
01:25
So the lithosphere is this top part up here.
01:29
So it's this area where it's the crust and the solid parts of the mantle.
01:35
So that's the lithosphere.
01:41
The asthenosphere is going to be that this region right here of the mantle.
01:46
It's the part right under the crust.
01:50
That is ductile and lets the crust and the solid parts move around...
