    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.

    Weathering and Soil Formation

    • Weathering of rocks contributes to soil formation by breaking down rocks into smaller particles, releasing minerals that enrich soil.
