The Cliffs at Gay Head

The Cliffs at Gay Head. The layers of clay are very very old, with a thin layer of glacial deposits on top. So why are they so high above sea level today? H ow is the Ice Age responsible for their visibility to us?. Some layers are 100 million year old deposits, from the Cretaceous.

Model of the Mineral Nutrient Cycle developed by P.F. Gersmehl in 1976

Soil is the top layer of the earth that is composed of disintegrated rock particles, humus, water and air. Litter is organic matter in and on the soil, it includes humus and leaf litter.
