fold mountains

Oceanic–continental

When an oceanic plate and a continental plate collide, the heavier oceanic plate sinks under the lighter continental plate and melts into the mantle

This process is called subduction

e.g. Nazca plate South American plate

continental-continental

when two continental plates collide, they buckle upwards.

e.g indian plate- eurasian plate

tourism

Settlement refers to places where people live, build homes and grow communities

Although largely unsuitable for settlement because they are difficult to build on, our mountain ranges are a major attraction for tourism

The folding of the Earth’s crust across the globe has created some of our most scenic and impressive landscapes

Anticlines and synclines

The syncline is usually seen in a valley

An anticline is when rock folded upwards and a syncline is when rock folded downwards

When two plates collide to form a fold mountain, these strata are crushed together and fold upwards to form fold mountains

Layers of rock make up the Earth’s crust – these layers are called strata

fold mountains are formed by

when two plates collide and their edges rise and buckle upwards to form a mountain
