MOUNTAINS!!(:
There are 3 different types of mountains. A folded mountain, a fault-block
mountain, and a volcano are the 3 types of mountains. A mountain is land that
rises steeply from the land around it. Most mountains
belong to ranges, a long line of mountains that each
formed at about the same time by the same process.
Ranes that are close to gether make up a mountain belt.
Most of the worlds major mountain belts are located
alongtectonic plate boundaries.
Some mountains have remains of ocean animals on
them, not just on the bottom but on the top too. An
oceanic plate sinks when it collides with a continental
plate. Some sea-floor scrapes off of the sinking plate
and onto the land/continent. So when the mountains
form from the plates pushing the land up, it brings the
ocan remains with it, meaning that they can be brought
up many kilometers away.
Some processes can push a mountain up while others
can wear it down. At Earth's surface, water and wind
break rocks apart and move the pieces away, off the
mountain. As long as a mountain pushes up faster than
it is being worn down, then it will contintue to grow
taller. Young mountains tend to be tall and steep, while
older mountains seem to be smaller and more slanted.
This happens because after a while the bulding process
of a mountains tends to slow down until it completely
stops, and wears away little by little. If tectonic plates
would stop moving, eventualy the land would become
completely flat.
A folded mountain is a mountain that forms as
continental crust crumples and bends into folds. It
forms as an oceanic plate sinks under the edge of a
continent or as continents collide.Earthquakes can also
be important to the upward of folded mountains. A
great deal of rock in the Himalaya belt has been
pushed up along reverse faults, which are common at
convergent boundaries.
Mountains that form as blocks of rock moved up or
down along normal faults are called fault-block
mountains. Fault block-mountains form as the
lithosphere is stretched and pulled apart by forces
within Earth. The rocks of the crust are cool and hard,
so when the plates move apart and stretch the land it
breaks the hard cool rock, making the fault-block
mountain. Both Folded mountains and fult-block
mountains form over millions of years. An easy way to
remember how folded mountains are formed is theyre
pushed up by slow, continual stress that cause the rock
to bed every once in a while, and forms where the crust
is being compressed. For fault block mountains, they
form earthquake by earthquake, as stress builds up in
the crust, its released by the movement of rock, and
forms where the crust is being streched.
