Geology
The geology of alpine habitats is that of granite. These igenious rocks first formed millions of years ago when re-hot ‘magma’ flowed upwards from the earths crust, before rising to its surface to form these granite outcrops.
Over time, weathering and erosion widen cracks in these rocks, slowly breaking down the granite. When moisture in these cracks freezes, it expands and wedges the rocks apart. Wind and rain help remove small particles from the surface.
The cracks in this granite provide a rocky habitat for animals and plants to grow and shelter in, particularly insects, lizards and snakes.
