hello friends I am your friend
stormy today I am going to explain about
desert when anyone speaks about desert
don't you start thinking about boring
dry and hot places well it's not like
that actually there are so much of cool
things about desert you guys are going
to learn today with stormy oh nothing is
visible here deserts are full of miles
and miles of sand dunes because the
desert is so dry the wind will grind
pebbles and sand into dust occasionally
a big windstorm will gather up this dust
into a huge storm dust storms can be
over 1 mile high and so thick with dust
you can't breathe they can travel for
over a thousand miles to many deserts
are rocky with speckled shrubs and
plants there are some deserts that are
icy and cold like North Pole desert and
desert of an Arctic the Sonoran Desert
can be very hot during the day and very
cold at night the largest hot and dry
desert in the world is the Sahara Desert
in northern Africa the Sahara is a sandy
desert with giant sand dunes it covers
over 3 million square miles of Africa
there is Starr desert of Rajasthan that
is situated partly in India and partly
in Pakistan it is considered to be 4,000
to 10,000 years old
other major deserts
include the Arabian desert in the Middle
East the Gobi Desert in northern China
and Mongolia and the Kalahari Desert in
Africa Patagonian desert in South
America and Great Basin desert in North
America deserts are primarily defined by
their lack of rain they generally get 25
centimeter around 10 inch or less rain
in a year they have dry soil little to
no surface water and high evaporation
they are so much try that now and then
rain evaporates before it can hit the
land imagine you're in a desert and
you're lost you've run out of water on
the horizon you see a giant glittering
puddle of water you pee you shout but
when you go near you don't find any
water actually it's a mirage mirages are
optical illusions that have fooled many
thirsty explorers this Mirage is a
reflection of light caused by bending of
light oh don't get sad look at this
beautiful place this place has plenty of
water and greenery this is called an
oasis
Oasis is the area within a desert where
there is sufficient water for permanent
vegetation to grow they also provide
habitat for animals and even humans if
the area is big enough in the desert we
see very less animals camel is the main
animal we see in a desert camels can go
without water for a week a thirsty camel
can drink 30 gallons of water in less 15
minutes animals that live in the desert
also have adapted to needing little
water desert animals prevent water
leaving their bodies in a number of
different ways some like kangaroo rats
and lizards live in burrows which do not
get too hot or too cold and have more
humid damp air inside these animals stay
in their burrows during the hot days and
emerge at night to feed other animals
have bodies designed to save water
scorpions and wolf spiders have a thick
outer covering which reduces moisture
loss
ah be careful this cactus plant may hurt
your legs
do you know only certain types of plants
can survive the harsh environment of the
desert these include cactus grasses
shrubs and some short trees you won't
see a lot of tall trees in the desert
most of these plants have a way to store
water in their stems leaves or trunks so
they can survive a long time without
water
today you have learned so much about
desert now it's time to remember this
