What is a transported soil? What will be an ideal response?

Question 2

How do the layers in exfoliation domes differ from the layers visible in spheroidally weathered
outcrops? What will be an ideal response?

Answer to Question 1

The word transported refers to the substrate upon which the soil is developed. In-place granite, for
example, is not considered transported. Ash, dust, river sediment, and glacial sediment are all
examples of transported materials upon which transported soils can develop

Answer to Question 2

The layered appearance of exfoliation domes derives from tension cracks produced by relieved stress.
Exfoliation domes are usually made up of rock masses formed deep underground where pressures are
higher. Once the overlying rock mass is eroded away, the load decreases, and the remaining rock mass
is able to expand and crack. Spheroidally weathered outcrops form mainly by chemical weathering.
Where pressures come into play, they are the result of mineralogical changes, such as clay formation
