 In this PowerPoint presentation, I will be talking about
the Earth’s core which includes the crust, lithosphere,
asthenosphere, mantle, outer core, and inner core.
Also, I will include some fun facts at the end of the
presentation.
 The first layer of the Earth is the Earth’s crust, which is

made up of two kinds of crust: the continental crust
and oceanic crust.
The oceanic crust is the crust that forms the bottom of
the ocean.
The continental crust is the crust that forms the
continents.
The crust consists of volcano’s, mountains, and etc.
The crust is about 500 to 1,000 degrees Celsius.

 The lithosphere is the layer between the crust and the
asthenosphere.
 The lithosphere is broken into sections by tectonic
plates.
 The lithosphere causes the earthquakes and tsunami’s
with the movement of the plates.
 The lithosphere is about 1,000 degrees celsius.

 The asthenosphere is the layer that lies between the
lithosphere and the upper mantle.
 The asthenosphere is a solid layer and the plates of the
lithosphere move at the top of the layer.
 The asthenosphere was found by scientists when an
earthquake occurred.
 The asthenosphere is around 1,500 to 2,000 degrees
Celsius.

 The mantle is the largest layer in the Earth’s core and it
is between the crust and outer core.
 The mantle is made up of rock that is very hot, but
solid.
 This layer of the Earth’s core is about 2,500 to 3,000
degrees Celsius.
 Also, the mantle has two layers: the upper and lower
mantle.

 The upper mantle is the layer between the crust and
the lower mantle.
 The upper mantle is made up of solid rock and deep in
the upper mantle there is magma.
 The upper mantle is like an ocean filled with magma.

 The lower mantle is the layer between the upper
mantle and outer core.
 The lower mantle is solid but the heat makes the rock
almost turn into a liquid form.
 Also, the lower mantle contains many kinds of
minerals.

 The outer core is the layer between the lower mantle
and inner core.
 It is one of the hottest layers of the Earth’s interior
with the temperature of 5,000 degrees Celsius.
 Scientists have not learned that much from the outer
core because of its heat.
 Mostly everything in this layer is magma.

 The inner core is the last layer of our journey into the
Earth’s core.
 The inner core is the hottest layer with the
temperature of 6,000 degrees Celsius.
 The inner core creates the Earth’s magnetic field with
the elements it has.
6th Grade Notebook
 Deep in the core there are radioactive elements.
 The outer core contains liquid iron.
 The continental crust is made out of the light colored
rock called granitic.
 The oceanic crust is made out of the dark colored rock
called basaltic.
