Question
What are
Landforms?
 A landform is any natural formation of rock and dirt, found on
Earth.
 A landform can be as large as a mountain range, or as small as a
hill.
 It can be as large as a continent, or as small as a pond.

 Mountains could be formed when molten rocks from deep within
the earth rise to the surface, pouring out in the form of lava from
volcanoes.
Mountains
 Or, sometimes the tectonic plates on the earth’s crust move
towards each other, the sediments deep below the earth’s surface
are squeezed up to form mountain ranges.

 Hills are lower than mountains but are higher than their
surrounding areas.

 Valleys are the low-lying areas between two mountains or hills.
 When rivers flow down the mountainsides and hillsides, it wears
off the rocks and soil.
Valleys
 Over a period of time, the water carves out v- shaped grooves.
These grooves get deeper and wider, finally forming low land
areas called valleys.

 A plateau is a flat topped highland with steep sides.
Plateaus
 They are basically areas of high flat land.
 Plateaus are usually surrounded by steep rock faces called cliffs.

 Plains are areas of flat land.
Plains
 You will find most big cities are located in plains. This is because it
is easier to build houses, buildings, roads and other structures in
the plains.

 Deserts are large, dry and hot areas of land which receive little or
no rainfall throughout the year.
Deserts
 Sand dunes are formed in deserts. Sand dunes are huge hills of
sand formed by the winds.
 Deserts have extreme weather conditions, days could be very hot
and nights very cold. This is because the sand absorbs heat fast
during the day and gives off heat quickly at night.
