Landscape Evolution Test 1

Front 1

Geomorphology 1

Back 1

The study of Earth forms.

Front 2

Geomorphology 2

Back 2

Includes ocean topography.

Front 3

Geomorphology 3

Back 3

Focus on surface forms and processes.

Front 4

Geomorphology 4

Back 4

Transcendant throughout a broad range of space and time.

Front 5

Geomorphology 5

Back 5

Study extends towards other Earth-like planets.

Front 6

Basic concepts 1A

Back 6

The same physical processes and laws that operate in today have operated thoughout geologic time. Although not necessarily with the same intensity as now.

Front 7

Basic concepts 1B

Back 7

The present is the key to the past.. Law of uniformitarianism (James Hutton) is the assumption that the same natural laws and processes that operate in the universe now have always operated in the universe in the past and apply everywhere in the universe.

Front 8

Basic concepts 2A

Back 8

Geologic structure is a dominant controlling factor in the evolution of landforms and is reflected in them.

Front 9

Basic concepts 2B

Back 9

"Structure" as used in geomorphology includes all those ways in which the Earth materials out of which landforms are carved differ from one another in their physical and chemical attributes.

Front 10

Basic concepts 3A

Back 10

Geomophic processes leave their distinctive imprint on landforms, and each geomorpholical process develops its own distinct assemeblage of forms.

Front 11

Basic concepts 3B

Back 11

Landforms are not haphazerdly developed with respect to another but certain landforms may be expected to be associated with eachother.

Front 12

Basic concepts 3C

Back 12

Equiformality: similar forms result from different processes. i.e. Martian gullies.

Front 13

Basic concepts 4A

Back 13

To a large degree the Earth's surface processes relief because the geomorphic proceses operate at different rates.

Front 14

Basic concepts 4B

Back 14

Some landscapes arise from desorderly processes. i.e. Scablands in Eastern Washington.

Front 15

Basic concepts 4C

Back 15

Cycle of erosion.. was a model for stream erosion and landscape development proposed by William Morris Davis in the late 19th century.

Front 16

Basic concepts 5A

Back 16

Complexity in a geomorphilogic system is nore common than than simplicity.

Front 17

Basic concepts 5B

Back 17

It is necessary to search for simplicity in geomorphical systems than complexity.

Front 18

Basic concepts 6A

Back 18

Little of the Earth's topography is is older than the Tertiary and most of it is no older than the Pleistocene.

Front 19

Basic concepts 6B

Back 19

Relict landscape elements remain despite Pleistocecne changes. In some cases vast relict landscapes persist. i.e Australia and Africa.

Front 20

Basic concepts 7A

Back 20

An appreciation for world climate is necessary for a proper undestanding of the varying importance of different geomorphic processes.

Front 21

Basic concepts 7B

Back 21

Landscapes reflect the influence of certain climatic processes by developing a characteristic assemblage of landforms. i.e. Climatic Geomorphology.

Front 22

Basic concepts 7C

Back 22

Geologic structure prodominates over climate influnecing landform assemblages.

Front 23

Basic concepts 8A

Back 23

Geomorphology, although concerned with modern day landscapes, attains it maximum usefulness by historical extension.

Front 24

Basic concepts 8B

Back 24

Historical extension may properly be refred to as paleomorphology.

Front 25

Basic concepts 8C

Back 25

We have returned to the pricipal of uniformitarianism.
