This term we will be looking at the
violent side of Planet Earth.
We will take a journey to the centre
of the Earth.
We will marvel at volcanoes and try to
outwit earthquakes.

What is the greatest

Tornadoes
Pandemics
Floods

Zombies?
Is our Earth itself the
greatest threat to life?
These are all images of tectonic hazards.
Tectonic hazards are created when the
surface of Earth breaks open or moves! To
find out why the Earth moves we need to
look at its structure.
The Structure of Earth
TASK Fill in your structure of the Earth sheets
The Layers of the Earth Rap
Throw your hands up for the layers
of the Earth!
Throw your hands up for what’s below
the surface!
Throw your hands up and let’s
discuss…
The inner core, outer core, mantle
and crust!
As you listen to the rap, write down
five NIFs (new interesting facts)
about the layers of the Earth.
The Shattered
Crust
The crust is made
of rock. But it is
not a smooth,
unbroken surface.
The crust a
cracked, broken
surface like a
jigsaw. Each broken
piece of the crust
is called a plate.

Recap Questions
1. Can you name the layers of the
Earth?
2. What is the crust broken up into?
3. How many plates can you name?
4. What evidence is there to tell us
that the continents once joined
together?
5. Why do the plates move?
6. How quickly do the plates move?
