Exam 11: Landmass Denudation

In polar and alpine regions,the thawing and saturation of the upper layer of soil results in a slow downslope movement called

Weathering is not influenced by vegetation.

Fence posts and utility poles leaning downslope is indicative of slump.

The consolidated or unconsolidated materials from which soils develop is known as

Weathering refers specifically to the physical (mechanical)processes that break down rocks and doesnʹt include the chemical processes that breakdown rocks.

Rust,formed by the reaction of iron and oxygen in the presence of water,is an example of

A slope is________ if its strength exceed denudation processes and________ if its materials are weaker than denudation processes.

The photograph shows an example of which mass movement process?

Exfoliation is an example of a chemical weathering process.

A talus slope is indicative of soil creep.

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

Frost wedging is an example of ________weathering processes.

Discuss the dynamic equilibrium model and the concept of geomorphic threshold.

Freeze/thaw cycles contribute to soil creep.

The concave lower portion of a typical slope is called a

The photograph is an example of a

When a landform system reaches a geomorphic threshold,it returns to the old system state.

Which of the following are examples of dripstones?

A landscape in a state of dynamic equilibrium experiences no change.

Chemical weathering always occurs in the presence of water.
