Geography ch 13

The dynamic equilibrium model of landscape evolution emphasizes a balance among forces, form, and process, rather than cyclical stages of development.

True

If Earth did not experience endogenic processes, the landscape would

be of very low relief as a result of weathering and erosion in the absence of uplift.

Chemical weathering is greatest under conditions of

higher mean annual rainfall and temperatures.

Other than the rock itself, the most important chemical substance needed for the majority of weathering processes is

water

Which of the following weathering processes does not involve water?

pressure-release jointing

Physical weathering dominates in warm, wet climates.

False

Soil thickness will decrease when soil production rates are greater than soil erosion rates.

False

Which of the following is incorrectly matched? a. stalagmite - formation built up from a cave floor b. sinkhole - doline c. karst towers - formations created by the merging of stalactites and stalagmites d. complex landscape of intersecting dolines - cockpit karst

c. karst towers - formations created by the merging of stalactites and stalagmites

Exfoliation occurs because

overlying rock is removed, thereby allowing the underlying rock mass to expand and fracture.

The yellow-red stains that occur on some rock surfaces are the result of __________ which is a form of __________ weathering.

oxidation; chemical
