What are fold mountains
Fold mountains are mountains that form when two tectonic plates move towards each other and collide. This collision causes the land to buckle and fold, creating mountain ranges
What are fold mountains
Fold mountains are mountains that form when two tectonic plates move towards each other and collide. This collision causes the land to buckle and fold, creating mountain ranges.
Examples of fold mountains
Examples of fold mountains include the Andes in South America and the Himalayas in Asia.
Formation of fold mountains
The collision of plates forces sediments and rocks to crumple and push upwards, forming fold mountains.
The force of the collision at these plate boundaries is so strong that it can lift the Earth’s crust, creating tall mountain ranges.
Fossils can often be found high in these mountains because the rocks that form them were once below the sea and have been lifted up.
Name the three main folding periods
The Caledonian, Armorican and Alpine foldings.
Explain the Caledonian fold mountains
Formed around 400 million years ago.
Found in places like Donegal, Wicklow, and Scotland.
These mountains have been worn down over time and have rounded peaks
Explain the armorican fold mountains
Formed about 250 million years ago.
In Ireland, they include ranges like the Macgillycuddy’s Reeks, the Galtees,
These mountains were once as high as the Alps but have since been eroded
Explain alpine fold mountains
Formed 30 to 35 million years ago, making them the youngest and highest fold mountains.
Examples include the Rockies in North America, the Alps in Europe, and the Himalayas in Asia
