Study Notes
Bogs
- Raised bogs form in depressions where rainwater accumulates, creating dome-shaped peat deposits, typically found in cool climates.
- Blanket bogs extend over large areas and slopes, forming continuous peat layers, typically found in areas with high rainfall and low temperatures.
Metamorphic Rocks
- Formed through heat from nearby magma chambers or deep burial.
- Formed through pressure from overlying rock layers or tectonic forces.
- Examples of metamorphic rocks and their parent rocks:
- Marble from limestone.
- Quartzite from sandstone.
Soil Formation
- Parent material determines the mineral composition and nutrient content of soil, influencing its fertility and texture.
- Comparison of limestone and granite as parent materials:
- Limestone forms alkaline soils suitable for agriculture.
- Granite forms acidic soils less fertile for agriculture.
- Identification of limestone as a parent material:
- Recognizable by its light color, often with visible fossils or marine remnants.
Glaciation and Gleisiation
- Glaciation: Formation and movement of glaciers over land.
- Gleisiation: Movement of ice in mountain areas.
Rock Types
- Classification of rock types:
- Quartzite: Metamorphic.
- Shale: Sedimentary.
- Basalt: Igneous.
- Minerals present in peat bogs in Ireland:
- Sphagnum moss, heather, and sedges.
- Minerals present in igneous rocks:
- Quartz, feldspar, and mica.
