The
Sahara desert has one of the most
extreme climates in the world.
It is so hot and dry during the
day that it can feel like being
in an oven. At night, the warm
air rises and escapes in the clear
skies into the atmosphere. Temperatures
fall dramatically, even to below
freezing.
The
Sahara has strong winds too.
They are called the Harmattan.
These winds can feel like a
hairdryer on full blast. Sometimes
the Harmattan whip up sand and
dust to make sandstorms. These
storms can really hurt, and
make it difficult to breathe!
Harmattan winds have carried sand
and dust from the Sahara as far
away as the UK. But the extra
sand high up in the atmosphere
can give us lovely sunsets!
Imagine
you and some friends are planning
to go camping in the Sahara
desert. What would you take
with you to survive the harsh
climate?
for
a worksheet.
Fill in what you would take
to the Sahara and why.
Compare your list
with your friends. Do you agree on
what are the most important things
to take?
Many
people think that the desert is
just made from sand, but the Sahara
also has big mountain ranges and
plains of gravel. For more pictures

Although
the Sahara is a hot, dry place,
there are islands of green called
oases
. At an oasis
, people can reach water near
the ground’s surface.
