Mountain  Erosion

We see the mountains being torn down with many forces involving frost shattering, frost heave, avalanches, screes, rock rivers, fans, winds, chemicals, rivers and more. Rivers carry the shattered mountain remnants on to develop the vast plains   and affect settlements throughout the world.  KANES explain to interested guests the processes and forces that are disassembling the mountains and disposing the material at long distances from them.  We look at ways of managing this process to help protect communities from these destructive forces. More on erosion
Glaciation	Glaciation We learn to recognise evidence of the world's most powerful erosion force and see the results of their past ice age activity.
Frost Shatter	Frost Shattering The second most effective erosion force is the shattering of the rocks and mountains by the force of freezing water.  Your KANES guide introduces study groups to locations to witness this amazing process.
Frost Heave	Frost Heave During winter we see freezing water force its way through the soil forming delicate crystal columns of sparking ice.  This process rips the soil from any plants leaving them to die and it leaves the soil ready to be carried by the precipitations.
Limestone Erosion *	Limestone Erosion * A chemical process - slow and methodical. We explore areas where this process occurs with caves, sink holes and more.
River Erosion	River Erosion Explore places where floods scour down rived beds and carry on deposits placed there during more placid flows. Compare river eroded valleys with glacier eroded valleys.
Screes, Rock Rivers & Fans	Screes, Rock Rivers & Fans Witness the clearest and most varied examples of these features. See how they affect settlements, land use and transport.  When time permits, we climb a scree flow to familiarise ourselves with its gradient, movement process, texture and the features of the rock fragments.
Weathering	Weathering We find excellent examples of naturally weathering limestone tors. These are constantly changing their shapes as a direct result of the strong winds and rain.
Braided Deposition	Braided Rivers Many different rivers in this zone carve chasms, gorges, valleys, waterfalls and caves.  They carry the eroded material collect broken mountains . We see them actually transporting the mountain materials to places where the current slows and they settle to full other parts of valleys, flood plains and to extend the land in the coast.  .
