Question 1C
Examine the impact of tectonic activity on the landscape of Ireland.
Worked Solution & Example Answer:Examine the impact of tectonic activity on the landscape of Ireland. - Leaving Cert Geography - Question 1C - 2019
Step 1
Impact of tectonic activity on the Irish landscape identified
Answer
Tectonic activity has significantly influenced the landscape of Ireland. One major impact is the formation of mountain ranges, specifically the Caledonian Mountains, which arose from tectonic forces. Another vital effect is the shaping of the land through processes such as folding and faulting.
Step 2
Examination
Answer
-
Formation of Mountain Ranges: The collision of tectonic plates led to uplift, resulting in the creation of the Mourne Mountains in County Down. This movement has shaped the rugged terrains and elevated landscapes seen today.
-
Folding and Faulting: Regions like the Burren in County Clare showcase limestone pavements formed through karst processes, influenced by tectonic movements that created fractures, allowing erosion to carve distinct landforms.
-
Earthquakes and Subsidence: While Ireland is relatively stable compared to other regions, minor seismic activity can lead to local subsidence and impact urban development, emphasizing tectonic influence on human geography.
-
Volcanic Activity: The remnants of ancient volcanic activity, such as the Giants Causeway, reflect tectonic processes, showcasing basalt columns formed through volcanic eruptions associated with plate movements.
-
Glacial Interactions: Tectonic uplift created landscapes that interact with glacial processes, leading to features like fjords along the western coasts, where glaciers shaped the valleys between tectonically uplifted areas.
