EXOGENIC PROCESS

• occurs on earth’s surface due to the influence of external forces

• exogenic process

• endogenic process

• mechanical weathering

• sand dunes

• Any accumulation of sand grains shaped into a mound or ridge by the wind under the influence of gravity 

• sand dunes

• weathering

• sand grains

• glacier

• Is the breaking down or dissolving of rocks and minerals at or near the earth’s surface 

• Weathering

• • Exfoliation 

• Exogenic Process 

• Mechanical Weathering 

Is the physical disintegration and reduction in the size of rocks without exchanging their chemical composition

• Mechanical Weathering 

• • Frost Wedging 

• • Salt Wedging (Honeycomb)  

• • Root Wedging (fracture to open) 

Is and uplift of under rock causes the top hard rock, like granite, to split into layers

• • Root Wedging (fracture to open) 

• Is the process by which water seeps into cracks in a rock, expands on freezing and thus enlarges the cracks
