GEOMORPHOLOGY
STRUCTURAL LANDSCAPES
Hilly landscapes
Karoo landscapes
HORIZONTALLY LAYERED
LANDSCAPES
Basaltic plateaus and
canyon landscapes
Hilly landscapes
Horizontally laid sedimentary rock
- If a hill is composed of layers of sandstone of varying resistance, a
flat-topped hill will emerge
, Igneous intrusions – sills
Igneous sill is formed by: when hot magma fills the space between two
sedimentary layers and cools and solidifies
Igneous rock is more resistant than the sedimentary rock
Top layer will erode when exposed
Basaltic plateaus and canyon landscapes
When basaltic lava cools and solidifies it forms a basaltic plateau
Solidified basalt is very resistant to weathering and only few rivers are able
to erode through the rock
This forms a canyon
A deep, narrow valley in a dry area
