-
Alluvial Fan - A fan-shaped, gently sloping mass
of stream deposits laid down on a plain or valley floor.
-
Anticline - A ridge structure resulting from the
folding of underlying rock layers. They are a common
structure where rocks have been compressed by tectonic
forces.
-
Delta - An accumulation of sediment at the mouth
of a river or stream.
-
DEM (Digital Elevation Model) - A digital dataset

-
Remote Sensing - The science of obtaining
information about an object by a device that is not in
contact with the object.
-
Rift Valley - A valley that forms along a
tectonic fault zones.
-
Sapping - Sapping is the subsurface flow of
groundwater along fractures in the bedrock.
-
Syncline - A trough-like structure resulting from
the folding of underlying rock layers. They are a common
structure where rocks have been compressed by tectonic
forces.
