1/18 Questions

Breakdown of rocks due to chemical, mechanical and temperature deferences.
- Erosion
- Weathering
- Fracturing
- Elasticity

About This Quiz

A test designed to test learners' understanding of Geomorphology.

2.

A flat high lying area than the surrounding areas.
- Horizontal layered rock
- Plateau
- Karoo Landscape
- Conical hill
Correct Answer

A. Plateau

Explanation

A plateau is a flat high lying area that is elevated compared to the surrounding areas. It is characterized by its horizontal layered rock formations. Plateaus are formed through geological processes such as uplift, erosion, and volcanic activity. They often have steep sides and a relatively flat top. Plateaus can be found in various regions around the world and are important for their unique ecosystems and geological features.

3.

A deep narrow valley in an arid region.
- Canyon
- Plateau
- Hilly landscape
- Basaltic landscape
Correct Answer

A. Canyon

Explanation

A canyon is a deep and narrow valley that is typically found in arid regions. It is formed through the erosion of the land by rivers or other natural forces over a long period of time. Canyons are characterized by steep sides and often have a river or stream running through the bottom. They are a common feature in desert landscapes and can be quite dramatic and visually stunning.

Is [valley of thousand hills, is a hilly landscape found in KZN] true or false?
- True
- False
Correct Answer

A. True

Explanation

The statement "valley of thousand hills is a hilly landscape found in KZN" is true. The Valley of a Thousand Hills is a region located in the province of KwaZulu-Natal in South Africa. It is characterized by its scenic hilly landscape, with numerous hills and valleys spread across the area. The name "Valley of a Thousand Hills" accurately describes the topography of this region, making the statement true.

5.

The relief of the Earth's surface.
- Geomorphology
- Topography
- Valley
- Basaltic landscape
Correct Answer

A. Topography

Explanation

Topography refers to the physical features of the Earth's surface, including its relief, such as mountains, valleys, and plains. It encompasses the study of landforms and their spatial distribution. Geomorphology is a branch of geology that specifically focuses on the formation and evolution of landforms. While topography is a broader term, valley and basaltic landscape are specific types of landforms that fall under the study of topography. Therefore, topography is the most appropriate answer as it encompasses the relief of the Earth's surface and the study of landforms.

6.

Removal of broken rocks by wind, water or ice.
- Weathering
- Erosion
- Movement
- Fracturing
Correct Answer

A. Erosion

Explanation

Erosion refers to the process of removing broken rocks by wind, water, or ice. It involves the transportation of these broken rocks from one place to another, often leading to the formation of new landforms. Weathering, on the other hand, refers to the breakdown of rocks into smaller pieces due to various physical, chemical, and biological processes. Movement and fracturing are more general terms and do not specifically describe the removal of broken rocks. Therefore, the correct answer is erosion.

7.

An isolated, flat-topped hill with steep sides that are smaller in area than the Mesa________

Correct Answer
Butte

Explanation
A butte is a type of isolated hill with a flat top and steep sides. It is smaller in area compared to a mesa, which is a similar landform but larger in size. Buttes are typically formed through erosion, where the surrounding rock is eroded away, leaving behind a prominent hill with distinct steep sides and a flat or gently sloping top.

Is [Fish river canyon is found in Mpumalanga Province] true or false?
- True
- False
Correct Answer

A. False

Explanation

The statement "Fish river canyon is found in Mpumalanga Province" is false. The Fish River Canyon is actually located in Namibia, not in Mpumalanga Province.

9.

Also known as parallel retreat
- Scarp
- Back wasting
- Reverse
- Reverse movement
Correct Answer

A. Back wasting

Explanation

Back wasting refers to the process of erosion or retreat of a scarp or slope in a backward direction. It is also known as parallel retreat scarp or reverse movement. This term is commonly used in geology and geomorphology to describe the gradual erosion and backward movement of a landform, such as a cliff or escarpment, due to various erosional processes like weathering, mass wasting, or fluvial action. The term "back wasting" emphasizes the backward or reverse direction of the erosion, highlighting the retreat of the landform.

________is the study of all physical features of the surface of the Earth, their arrangement and origin in relation to their geological structure

Correct Answer
Geomorphology

Explanation
Geomorphology is the study of all physical features of the surface of the Earth, their arrangement, and origin in relation to their geological structure. It focuses on understanding the processes that shape the Earth's landforms, such as mountains, valleys, rivers, and coastlines. By studying geomorphology, scientists can gain insights into the Earth's past and present landscape evolution, as well as predict future changes.

The Prime Meridian is a line of longitude that, by international agreement, marks 0° longitude.
- True
- False
Correct Answer

A. True

Explanation

The Prime Meridian is the designated zero-degree longitude line, established as the global reference for longitudinal coordinates. It runs through Greenwich, England, dividing the Earth into Eastern and Western Hemispheres. This standardized marker is crucial for navigation, timekeeping, and geographic mapping.

12.

A sharp-pointed hill that results due to the weathering and erosion of a Butte is________

Correct Answer
Conical Hill

Explanation
A conical hill is formed as a result of the weathering and erosion of a butte. Over time, the forces of weathering and erosion wear away the softer rocks and sediments around the butte, leaving behind a sharp-pointed hill with a conical shape. This process typically occurs in arid or semi-arid regions where the lack of vegetation and water accelerates the erosion process. The conical hill is a distinct landform that stands out in the surrounding landscape and is a result of the ongoing geological processes shaping the Earth's surface.

13.

An isolated, flat-topped hill with steep sides that are smaller in area than the canyon ________

Correct Answer
Mesa

Explanation
A mesa is a type of isolated hill with a flat top and steep sides. Unlike a canyon, which is a deep and narrow valley with steep sides, a mesa has sides that are smaller in area. This means that a mesa has a larger flat top compared to its steep sides. Therefore, the correct answer for this question is "mesa".

14.

Fine-grained solid resulting from erosion that settles at the bottom of a liquid ________

Correct Answer
Sediments

Explanation
When erosion occurs, small particles of rock, soil, or other materials are carried away by water or wind. These particles eventually settle at the bottom of a liquid, forming a fine-grained solid called sediments. Sediments can accumulate over time and create layers of different materials, providing valuable information about the history and composition of the area.

The _______ is the layer of the Earth's atmosphere that extends from about 50 to 80 kilometers above the surface and is characterized by decreasing temperature with altitude.

Correct Answer
Mesosphere, mesosphere

Explanation
The mesosphere is the third layer of the Earth's atmosphere, situated above the stratosphere and below the thermosphere. It is characterized by a significant decrease in temperature with altitude, reaching as low as -90°C (-130°F). The mesosphere plays a crucial role in protecting Earth from meteoroids, which burn up upon entering this layer due to friction with the atmospheric gases.

________they form when sediments are deposited and then compacted to form layers of sedimentary rocks.

Correct Answer
horizontal rock strata

Explanation
Horizontal rock strata refers to layers of sedimentary rocks that are formed when sediments are deposited and then compacted over time. This process typically occurs in a horizontal orientation, meaning that the layers are parallel to the Earth's surface. The deposition and compaction of sediments lead to the formation of distinct horizontal layers, which can be observed in sedimentary rock formations.
