Worked Solution & Example Answer:(i) Select any one of the following surface processes: • Marine action • River action • Glacial action - Leaving Cert Geography - Question 1 - 2011
Step 1
Select any one of the following surface processes: Marine action
Answer
I have selected Marine Action as the surface process for this question.
Formation of Two Irish Landforms Due to Marine Action
-
Sea Cliffs
- Formation Process: Sea cliffs form due to the erosive action of waves. As waves crash against the coastline, they erode the rock face, leading to the undercutting of cliffs, which causes sections to collapse over time.
- Diagram: A diagram illustrating the process of erosion showing the undercut cliff and collapsing sections would greatly aid in understanding this formation.
-
Sea Stacks
- Formation Process: Sea stacks originate from the erosion of headlands. As waves erode parts of the headland, they may leave isolated columns of rock standing in the water. Over time, these columns can become sea stacks.
- Diagram: A diagram that shows the process of headland erosion ending in the formation of a sea stack would effectively demonstrate this process.
Step 2
Describe and explain any two processes of mass movement.
Answer
Two Processes of Mass Movement
-
Landslides
- Process Description: Landslides occur when a mass of earth or rock falls down a slope due to gravity. This can be triggered by factors such as heavy rainfall, earthquakes, or human activities such as construction disrupting the ground.
- Significant Responses: Landslides can cause significant property damage, block roads, and may result in fatalities. Proper land management and monitoring are crucial in preventing landslides in vulnerable areas.
-
Soil Creep
- Process Description: Soil creep is a slow, gradual form of mass movement where soil particles move down a slope over time, primarily influenced by gravity. You may notice tilting fences or trees as indicators of soil creep.
- Significant Responses: While less dramatic than landslides, soil creep can lead to persistent damage to structures over time, making it crucial to recognize and address.
