GEOGRAPHICAL INVESTIGATIONS FOR THE LEAVING CERTIFICATE

Our one-day projects are specially designed for the geography fieldwork investigation topics each year. In all our projects students are involved in using various items of equipment to make measurements and collect data that can be used for presentation and analysis.

2018 projects

TOPIC 5: TEST THE HYPOTHESIS THAT GEOMORPHIC PROCESSES OF EROSION SHAPE THE LANDSCAPE IN A FLUVIAL, COASTAL OR GLACIAL ENVIRONMENT WITH REFERENCE TO ONE SPECIFIC LANDFORM.

In this study students will use secondary sources to estimate the amount of cliff edge in Liscannor bay. Then they will examine two different cliffs - examining the rock material and assessing the effect of different geomorphic processes. Measurements include cliff height, pebble shape, wind speed and direction plus wave frequency and type. Observations and sketches will be made at each location.

TOPIC 6: THE IMPACT OF GEOMORPHIC PROCESSES ON THE SURFACE LANDSCAPE IN A KARST ENVIRONMENT.

Two projects are available, both have been used before:

1: A study of limestone pavement at Black Head, Co. Clare.

A detailed study of the development of a limestone pavement. Measurements of depth, width and direction are made of a series of grykes using a transect line. These results will be analysed to test if gryke depth (and width) increases over time; and if the grykes have a random orientation. A number of glacial erratics and associated pedestals will be examined to estimate a rate of limestone erosion. Sketches of a number of features will also be made.

 2: A study of limestone erosion near Mullach Mor, Co. Clare.

 This study looks at the development of the Burren landscape in broad terms using the cycle of erosion concept. Two locations at the mature stage and old age stage are visited so a number of features will be seen – limestone pavements, turloughs and poljes.

GENERAL BURREN STUDIES

KARST FEATURES
The limestone landscape of the Burren is unique in Ireland and examples of most karstic land forms can be seen here. The extensive limestone pavements with their clints and grykes clearly illustrate the process of chemical erosion.
CAVES
Caves are an important feature of limestone areas and extensive caves are known beneath the Burren's surface. Instructors are available who can lead small groups into wild caves.
DRAINAGE PATTERNS
Near Lisdoonvarna, the limestone is overlain by impermeable rock with surface drainage providing a strong contrast to the high Burren where there are many dry valleys and closed depressions ranging from small dolines and turloughs to the large polje at Carron.
GLACIATION
There are many excellent examples of glacial action in the Burren. These include glaciated valleys, moraines and erratics.
