Landscape
Northern Ireland includes lowland basins, rolling hills and several distinct upland areas. Lough Neagh occupies a large central depression. The coast varies from sandy shores and sea loughs to rocky cliffs.
The Mourne Mountains rise in the southeast, while the Giant’s Causeway on the north coast exposes basalt columns formed as lava cooled. These are different geological landscapes within a relatively small area. Rivers connect inland basins with surrounding coastal waters.
