Introduction The earth is shaped by both internal and

external processes Internally, tectonic processes form the

lithosphere Externally gradational processes also

shape the lithosphere These include: rivers, winds, glaciers, and

waves

Rivers

Rivers cut deep valleys and create large deltas

Winds

Winds carves beautiful rock formations and carry sands

Glaciers Glaciers flow over continents while slowly

carving out the land and dropping large boulders…

Waves

Waves and currents cut into coastlines and polish sandy beaches….

The Other Gradational Force…

Humans are a gradational force This picture is an example of the effects of over

forestation
