Climate And Denudation

Climate and Denudation

1. Climate and Denudation

2. Climate and Denudation processes
•Mountain building processes change climates
but climate can also change relief
•Ice, water and wind are all elements in the
denudation process
–They corrode the land surface
–They transport the weathered the material
–They deposit that material elsewhere
–This modifies the landscape

3. Denudation processes
•The main denudation processes are
–Weathering
–Mass movement
–Erosion
–Deposition
•Most active at high altitudes
–Vegetation is unable to protect steep, ash covered
volcanic slopes from the weather

4. Read the text on.......
•The work of wind
•The work of running water
•Running water and the TVC

5. Page 24
•How do river patterns in volcanic areas differ
from those of non-volcanic areas?
•What do these patterns tell you of the
interactions between the processes of
volcanism and erosion by running water

6. Page 31
•What differences are there between drainage
patterns on Ngauruhoe and Tongariro?
•Suggest a reason for the difference in terms of
volcanic processes

7. All spatial patterns are the result of a
process
•Spatial pattern
–An arrangement of information in terms of physical
space
•What have we talked about today that
suggests this?
–Patterns of drainage suggest landform shape
•The process of drainage creates spatial patterns
–Patterns of andesite volcanoes suggest faultlines
•The process of volcanism creates the pattern of
faultlines
