Landforms and Processes Involved in Their Formation

Question 1

The word is derived from the Greek god of the winds, Aeolus. They are formed by the chemical and mechanical action of the wind.

Answer 1

Aeolian Landforms

Question 2

These are mounds or small hills made up of sand,
measuring between 1-10m high. They may be
dome-shaped, crescent-shaped, linear-shaped, or
parabolic.

Answer 2

Dunes

Question 3

Examples of Dunes

Answer 3

Duna Federico Kirbus – Catamarca, Argentina

Question 4

This is a predominantly silt-sized sediment formed
by the accumulation of windblown dust. It appears
yellowish or brownish in color and it exhibits “cat
steps”.

Its thickness ranges from few centimeters to about 100m. Is a product of glacial activity in an area. It is commonly found in Europe and Mississippi Valley and Asia.

Answer 4

Loess

Question 5

Example of Loess

Answer 5

Loess Plateau, Chinese

Question 6

They are also known as Rock Pedestal, is a
naturally occurring rock that resembles the shape of a mushroom.
They are formed by earthquakes or glacial action. A typical mushroom-shaped landform that is formed by the action of wind erosion.

Answer 6

Mushroom Rock

Question 7

Example of Mushroom Rock

Answer 7

Loess Plateau, Chinese

Question 8

is the wearing away of the landscape by
different agents like water, wind and ice.

Different landforms created on the surface of the
earth because of _________.

Answer 8

Erosional Landforms

Question 9

Also known as Table Mountains,
these are elevated areas of land with a flat
top and sides that are usually steep cliffs.

They are usually surrounded by a
resistant rock known as a cap rock.

Answer 9

Mesa

Question 10

Example of Mesa

Answer 10

The Grand Mesa, Western Colorado, USA

Question 11

It is almost similar to mesa as it has a flat-topped hill and
steep sides and are formed in arid to semi-arid desert condition.

The difference is that it covers a smaller amount of area
when compared to a mesa. Its name originated from a French
word which means “hillrock” or small hill.

They are formed by erosion when a hard cap rock overlies a
layer of less resistant rock

Answer 11

Butte

Question 12

Example of Butte

Answer 12

Elephant Butte, New Mexico, USA

Question 13

Sometimes referred to as gorge, is a deep ravine between cliffs that is often carved from the landscape by a river, wind, or glacier.

It may appear like a valley except that it is deep seated, narrow, and surrounded by steep sides.

Unlike other landforms, canyons were not produced by tectonic activities or natural disasters but were influenced by
water and wind erosion over long period of geologic time.

Answer 13

Canyon

Question 14

Example of Canyon

Answer 14

Grand Canyon, Northern Arizona, USA

Question 15

These are the landforms that rise higher than the rest of their surroundings. They exhibit slopes, summit area, and local relief.
They have steep slopes and a summit, which is the highest point of elevation. Are formed when tectonic plates collide and push land upwards over millions of years, and
shaped by wind and water erosion.

Answer 15

Mountainous Landforms

Question 16

Are landforms that are controlled by geological
processes that form them and continually act on them after their formation. can be identified from its opening at the top called vent. It’s cone-shaped structure or edifice is carved
out by the more or less symmetrical accumulation of lava and
other pyroclastic materials around its central vent system.

Answer 16

Volcanoes

Question 17

Example of Volcanoes

Answer 17

Mayon Volcano, Albay, Philippines

Question 18

Are elevated portions of lands that are formed by geologic activities such as faulting. They are usually covered with grass and are used as grazing lands for goats, cattle, and carabaos.

They are smaller than mountains, only about 300m high, with sloping sides unlike the steepness of the latter.

Answer 18

Hills

Question 19

Examples of Hills

Answer 19

Chocolate Hills, Bohol, Philippines

Question 20

Low-lying are of land situated between hills or mountains. They are usually formed by actions of rivers and glacier.

(2) what are the shapes?

Can be further classified as vale, dell, mountain
cove, hollow, and coon or hanging valley.

Answer 20

Valley or Dale

V-shaped when carved out by water and U-shaped when carved out by glaciers.

Question 21

Examples of Valley or Dale

Answer 21

Grand Canyon, Arizona, USA

Question 22

Are result of glaciers. Were created by the movement of large ice sheets during the Quaternary Glaciations (Pleistocene Glaciation).
There are two types of glaciers, alpine and continental glaciers.

Answer 22

Glacial Landforms

Question 23

Are slow-moving rivers of ice that flow from high mountains.

Example: Gorner Glacier, Valais, Switzerland

Answer 23

Alpine Glacier

Question 24

Are continuous masses of ice that are
much larger than alpine glaciers. Small continental glaciers are
called ice fields. Big continental glaciers are called ice sheets.

Greenland and Antarctica are almost entirely covered with
ice sheets that are up to 3500 m (11 500 ft) thick.

Answer 24

Continental Glacier

Question 25

These are landforms that underwent sedimentation, erosion or deposition on the riverbed. It’s term derives from the Latin word fluvius that means river.

Answer 25

Fluvial Landforms

Question 26

Are the landforms along the coastline that are mostly
formed by erosion and sediments from waves, longshore currents, rip currents, tides, and climatic factors like wind and rainfall, and temperature

Answer 26

Coastal Landforms

Question 27

Typically, a low-lying triangular area located at the mouth
of rivers where it meets an ocean, seas, or estuaries. It contains
rich soil which has been washed away and deposited by
running water.

Alluvium refers to the sediment that has accumulated due
to the interaction of delta and bodies of water.

Answer 27

Delta

Question 28

Also known as byland or biland, is a piece of land that projects into a body of water and is connected to the mainland by an isthmus

They are formed by lithospheric movement, water elevation and erosion.

Answer 28

Peninsula

Question 29

It is formed when moving water in
a steam erodes the out banks then widens
its valley. It has a concave
bank (inner bank) and a convex (outer
bank) bank.

Deposition of sediments occur in the
inner bank, whereas erosions at the outer
edge.

Answer 29

Meander

Question 30

Are steep faces of rock and soil that are formed by destructive waves. Waves crashing against the coastline erode until a notch is formed.

The erosion of this notch undercuts the ground above it until it becomes unstable and collapses. This process repeats itself and will continue to retreat.

Answer 30

Sea Cliff
