Background Knowledge:
Revise what class has already learnt about natural disasters.
Define – DISASTER, NATURAL
Discuss local natural disasters – floods, drought.
Discuss global natural disasters – tsunami, volcano, earthquake, fire, etc
Tell learners you are going to look at a specific natural disaster – earthquakes, and an EXPLANATION on
how they occur.
Summary of the text:
In this text, you will read an explanation of how an earthquake occurs.
First, there is a definition of what an earthquake is. Then you will read about the crust of the earth and the
inside of the earth.
The next section tells you that there are cracks in the crust and what happens when these cracks are
pushed together and then break apart. Then you will read about the vibrations that move outwards from
where the crust is broken. The vibrations cause the earthquake. Lastly, you will read about what the place
where the earthquake starts is called.
Joint Construction
Key words
1. Earthquake- Shaking of the earth – Caused - Pieces
of the crust - Suddenly shift
2. Thin outer layer – cold – brittle – rock – compared
to – hot rock – inside
3. Full – large – small – cracks – faults
4. Two pieces – next to each other – pushed –
different directions –stick together – long time –
eventually – forces pushing – break apart – move
5. Sudden shift – shakes – rock around it –
6. Seismic waves – travel outwards – all directions –
earthquake
7. Underground location – rock first broke apart –
shifted –focus
Example of Joint Construction
An earthquake is when the earth shakes. The
earth has a cold crust on the outside and hot rock
inside. The crust has many cracks in it. Sometimes
pieces of the crust are pushed by forces and they
break apart. When they break, the whole crust
shakes and waves, called seismic waves, travel
outwards.
The place where an earthquake starts is called the
focus of the earthquake.
Comprehension Questions (2 per level)
Literal: (In the text – HERE)
1. What is the place where the earthquake starts called?
2. What is the outside of the earth’s crust like?
Inferential: (Clues in the text – HIDDEN)
3. How does the outside of the earth (crust) differ from the inner core?
4. What pushes the pieces of rock apart?
Interpretive: (Use text as background for drawing conclusions – HEAD/HEART)
5. Why do you think the rocks don’t move all the time?
6. Why do some people live on fault lines?

Phase 6
Text for learners
An earthquake is the shaking of the earth caused by pieces of the crust of the Earth that
suddenly shift. The crust, the thin outer layer, is mostly cold and brittle rock compared to
the hot rock deeper inside. This crust is full of large and small cracks called faults. When
two pieces that are next to each other get pushed in different directions, they will stick
together for a long time (many years), but eventually the forces pushing on them will force
them to break apart and move. This sudden shift in the rock shakes all of the rock around it.
These vibrations, called seismic waves, travel outward in all directions and are called an
earthquake. The underground location where the rock first broke apart or shifted is called
the focus of the earthquake.

When two pieces that are next to each other get pushed in different directions,
E – different directions

but eventually the forces pushing on them will force them to break apart and move.
E- forces – force (noun and verb)
E- try keeping up pressure and see how things have to give
SENTENCE MAKING
Divide the sentence into wordings (put vertical lines between groups) and then write the cues above each section. Don’t try and do too many sections.
Learners will cut their sentences up as you give the cues, muddle the word groups up and then sort them again. Learners correct themselves.
