Transcript How Many Licks to the Earth`s Core

Have you ever wondered….
• How the layers of the earth
are ordered and what are the
names of the layers?
1. The center of the earth consists of
hot rock and is called the inner core
(made of solid iron and nickel).
2. There is also an outer core (made of
liquid iron and nickel).
3. The next level is hot, molten rock
called mantle.
4. The layer that we walk on is the
crust.
1. The Crust
1. The earth’s outer layer of
rock
2. 5-20 MILES THICK!!
3. Has mountains, ocean floor,
volcanoes, and land
2. The Mantle
1. The second layer between the
crust and outer core
2. Is solid rock except for the
part next to the crust, where
there is thick liquid
3. 1,800 MILES THICK!!
3. The Outer Core
1. The outer part of the core is
liquid and HOT!
2. It gets hotter the deeper you
go (around 9,000 degrees F in
the center—your oven only goes
to about 600 degrees F).
3. It’s so hot that rock melts.
Melted rock is called MAGMA.
4. 1,400 MILES THICK!
4. The Inner Core
1. 800 MILES TO CENTER!
2. Shaped like a ball, or sphere.
3. Solid
