Landforms Exam 2 Possible Questions

The dynamic equilibrium model refers to

A balancing act between tectonic uplift and rates of denudation by weathering and erosion in a given landscape

Salt-crystal growth (salt weathering) is prevalent in which climate type?

Arid

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.

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

Carbonation

Hydrolysis, hydration, oxidation, and carbonation are all examples of ________ weathering processes.

Chemical

When rock is broken down and disintegrated in the presence of water and with chemical alterations to the rock, the process in operation is

Chemical Weathering

Which portions of a slope overlap substantially?

Debris slope and waning slope

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

Denudation

Chemical weathering is greatest under conditions of

Higher rainfall and temperatures

In which climates would rocks experience the highest amounts of chemical decomposition and decay?

Hot and wet

Which of the following is not a type of physical weathering process?

Hydrolysis

Because the climate of a region slowly changes and tectonic adjustments slowly occur, the landscape

Is continuously adjusting, AND in a state of dynamic equilibrium, but NOT constantly at a threshold

Factors influencing the weathering process include

Rock composition and structure, climate, and vegetation

Which of the following is not exogenic in nature?

Tectonic uplift

Hydration involves

The addition of water to a mineral with little overall chemical change.

The convex upper portion of a typical slope is called a

Waxing Slope

Which of the following weathering processes does not involve water?

pressure-release jointing

After a threshold is crossed, the landscape

Adjusts to a new equilibrium condition

The science that specifically studies the origin, evolution, form, and spatial distribution of landforms is

Geomorphology

The uplift of mountains is caused by

Endogenic processes

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

Oxidation

Frost wedging is an example of ________ weathering processes.

Physical

Salt-crystal growth (salt weathering) is an example of ________ weathering processes.

Physical

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

Physical Weathering

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

water
