Folding and Faulting
When plates collide with each other, the pressure becomes so great that the earth’s crust becomes buckled and arches upwards, forming Fold Mountains.
Some Fold Mountains include the Alps, the Rocky Mountains and the Andes.
These were formed during the Alpine foldings about 35 million years ago.
Folding
Our youngest Fold Mountains were formed during the Armorican Foldings about 250 million years ago!! These are found in Kerry, the Macgillicuddy Reeks.
Irelands Fold Mountains.
The innermost part of the Earth is known as the Inner Bore Slabs of the Earth’s Crust that float on the Mantle are known
as Plates The outer core is made of hot molten metal When plates collide mid ocean ridges can form Earthquakes can happen when plates separate Mount Everest is a fold mountain The McGillycuddy’s Reeks were formed during the Armorican
foldings The inner core is made of Hot Solid Metal
