Mountains
Where do mountains come from?
• Mountains are formed when two plates within
the earth’s crust crash together.
• The land shoves up and forms a mountain.
• It is usually called a mountain when it is higher
than 600 metres. Less than this is called a hill.
• They are made up of rock & earth.
How mountains look

sides and sharp or slightly rounded ridges

Parts of a mountain
• The summit, or the top of a mountain;
• The slope, or side of the mountain
• A very deep valley between young
mountains is known as a gorge.
Types of mountains
• Mountains are formed by slow but gigantic
movements of the earth's crust (the outer layer
of the Earth).
• The Earth's crust is made up of 6 huge slabs
called plates, which fit together like a jigsaw
puzzle. When two slabs of the earth's crust
smash into each other the land can be pushed
upwards, forming mountains.
Mountain formation
• Mountains form in different ways
• Sometimes the crust has folded and
buckled, sometimes it breaks into huge
blocks. In both cases, great areas of land
are lifted upwards to form mountains.
• Other mountains are formed by the earth's
crust rising into a dome, or by volcanic
activity when the crust cracks open.
Some interesting facts
• Mountains exist under the sea.
• The tallest mountain in space is on Mars.
• The highest 14 mountains in the world are
found on the Himalayas, in India, Nepal &
China.
• Some mountains have frozen rivers on
them called glaciers.
