Exam 14: Weathering, karst Landscapes, and Mass Movement

Which is the process that works in place to break down rock at Earth's surface through disintegration of rocks into mineral particles or dissolving it into water?

Frost wedging is the result of repeated freeze/thaw cycles.

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

The dynamic equilibrium model considers the balance between endogenic and exogenic processes.

Stalactites and stalagmites are examples of dripstones.

In most areas,which is the upper surface of bedrock that is partially weathered to broken-up rock?

The angle of repose typically ranges from 15° to 30° from horizontal.

Which is likely the weathering process responsible for breaking this marble?

Chemical weathering is greatest under which conditions?

The angle of repose represents a balance between gravity and friction and shear.

Which is a steep scarp or cliff whose presence indicates an outcrop of resistant rock?

Which of the following is a type of chemical weathering process?

Which are the consolidated or unconsolidated materials from which soils develop?

Which of the following is not necessary for well-developed karst to form?

All processes that cause reduction and rearrangement of landforms are included in which term?

When rock is broken down and disintegrated without any chemical alterations,which is the process in operation?

Describe the forces acting on a slope,and also the various physical aspects of a slope,such as waxing slope and debris slope.

Which are extensive landscapes formed by the dissolution of limestone and other carbonate rock and characterized by pitted,bumpy surface topography,poor surface drainage,and well developed solutions channels?

After a threshold is crossed,which best describes the landscape?

When rainwater attacks formations of limestone,the minerals dissolve and wash away with the mildly acid rainwater.Of which is this an example?
