Exam 14: Weathering, karst Landscapes, and Mass Movement

Which process and which type of weathering are correctly paired to best describe the yellow-red stains that occur on some rock surfaces?

Why are plants important to the development of karst?

Which occurs because water expands by as much as 9% of its volume as it freezes?

When do landslides occur?

Landscapes in a dynamic equilibrium show ongoing adaptations to ongoing changes occurring in a landscape.

The angle of repose represents a balance between the driving force and resisting force.Which of the following is the driving force?

Which are a category of processes produced by human-induced mass movements?

Frost wedging is an example of which weathering process?

Vegetation is necessary for the development of karst topography.

Karst topography involves the chemical weathering of granite landscapes.

Which is the principle that landscape formation is balanced between endogenic and exogenic processes?

The presence of talus slopes indicates that which occur?

Weathering refers specifically to the physical (mechanical)processes that break down rocks and doesn't include the chemical processes that breakdown rocks.

Which is the maximum angle at which soil,sediment,and rock will remain without moving downslope (e.g.a stable slope)?

If material is to move downslope,it must overcome which forces?

Chemical weathering is greatest under which conditions?

In what ways can water be involved in physical and chemical weathering processes?

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

In the spring of 1903 in Frank,AB,about 82 million tonnes of rock and sediment moved down the east side of Turtle Mountain and surged up the other side of the valley.Of which mass movement is this an example?

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