1 Processes And Landforms Along Plate Boundaries Flashcards
(4) Classification of Landform
Aeolian Landforms
Erosional Landforms
Mountainous and Glacial Landforms
Fluvial and Coastal Landforms
are formed by the chemical and mechanical action of the wind.
Aeolian Landforms
are mounds or small hills made up of sand.
Dunes
A predominantly silt-sized sediment formed by the accumulation of windblown dust. It appears yellowish or brownish in color and it exhibits “cat steps”
Loess
also called rock pedestal, is a natural occurring rock that resembles the shape of a mushroom. Formed by earthquake or glacial action.
Mushroom Rock
created from exclusively erosional and weathering activities.
Erosional Landforms
also called table mountains. They are elevated areas of land with a flat top and sides that are usually steep cliffs.
Mesas
Almost similar to mesas as it has a flat topped hill and steep sides are formed in arid to semi-arid desert conditions. It covers a smaller amount of area
Buttes
Sometimes called “gorge” is a deep ravine between cliffs that is often carved from the landscape by a river, wind or glaciers.
Canyons
They rise higher than the rest of their surroundings.
MountainousLandforms
are controlled by geological processes that form them and continually act on them after their formation.
Volcanoes
Are elevated portions of land that are formed by geologic activities such as faulting. They are usually covered with grass and smaller than mountains.
Hills
Are low-lying areas of land situated between hills or mountains.
Valleys
Are the results of the actions of the glaciers. Glaciers are huge slow-moving bodies of ice.
Glacial Landforms
There are two main types of glaciers, namely:
alpine and continental
(glacial landforms)
are formed in high mountains
alpine glaciers
(glacial landforms)
are formed in cold polar regions
continental glaciers
are those that underwent sedimentation, erosion, or deposition on the river bed.
Fluvial and Coastal Landforms
Typically a low-lying triangular area located at the mouth of rivers where it meets an ocean, a sea, or an estuary.
Delta
Also called byland or biland, is a piece of land that projects into a body of water and is connected with the mainland by an isthmus.
Peninsula
is a bend in a sinuous watercourse of river.
Meander
are highly rocky coasts that plunge down the edge of the sea.
Sea Cliffs
are flat and broad land areas that have no great changes in elevation when measured with reference to the sea level.
Plains
also known as table lands or flat-topped mountains, are portions of land elevated thousands of feet above their surroundings.
Plateaus
