Fold Mountain question

Where - Munster Ridge and Valley in Ireland

When - Formed 250MYA in Munster

Why - African and Eurasian plate collided, causing land to buckle upward

How:

Compression caused by two plates colliding, caused rock strata to fold into anticlines and synclines.

Softer rock like shale was eroded, exposing the harder sandstone

Trellised drainage pattern developed by rivers moving south to the sea

Examples of Fold Mountains - Macgillycuddy Reeks in Kerry and Alps in Europe

Types of folds:

Anticline – upfold/top of the fold/peak ​

Synclines – downfold/bottom of the fold/valley

Limbs - Sides (of the fold)
