Summary

  • Exogenous processes gain their energy from the Sun. They transform the Earth by wearing down its surface, transporting loose material and by piling up this material in different locations.
  • The four most important forces of erosion are flowing water, ice, waves, and the wind.
  • Flowing water erodes the river's curves and carries loose material with itself, creating meanders, sandbanks, and deltas. 
  • Ice and the glacial till it carries can erode rocky surfaces, forming glacialized rocks and U-shaped valleys.
  • Waves, ice and wind transform the seashore, forming steep banks, shallow beaches and other formations such as rauks.
  • Wind can carry sand and other materials, forming loess, dunes and rock pedestals.
  • Key words: exogenous processes, erosion, weathering, U-valley, V-valley, delta, dune.
