Folding

Folding:When moving plates collide with each other, tremendous compression (pushing together) occurs where the plates meet. This compression may cause the earths crust to become very slowly buckled and arched upwards, forming fold mountains.


Examples:Alps in Europe

                The Rocky Mountains in North America

Inside The Earth

Crust: This thin outer shell of the earth is made up of solid rock.

Mantle: The mantle is so hot that some rocks there are semi-molten and flow about in slow-moving currents.

Core: The centre part of the earth is very hot.

Plate: Big Slab of the Earth's crust.

Plate Boundary: Where plates meet.
