Fold mountains like the Alps and Andes are formed when tectonic plates collide and the pressure causes the earth's crust to buckle upwards. Some of the youngest fold mountains, like those found in Kerry, Ireland, were formed during the Armorican foldings approximately 250 million years ago when plates collided and the crust arched to create mountain ranges. The inner structure of the Earth consists of a solid inner core surrounded by a liquid outer core and mantle, with slabs of crust that form tectonic plates that move and interact at plate boundaries.

2.  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.

6.  Our youngest Fold Mountains were formed during the
Armorican Foldings about 250 million years ago!!
These are found in Kerry, the Macgillicuddy Reeks.

8.  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
