1.
What type of landforms is characterized by depressions?
Correct Answer
D. Valleys
Explanation
Valleys are a type of landform characterized by depressions. Valleys are low-lying areas between hills or mountains, often formed by the erosion of rivers or glaciers. They typically have a U-shaped or V-shaped cross-section and are often associated with flowing water. Valleys can vary in size and shape and are commonly found in mountainous regions.
2.
Which of these landforms is a shoreline feature?
Correct Answer
D. Bays
Explanation
Bays are a type of landform that is considered a shoreline feature. Bays are bodies of water that are partially enclosed by land, with a wide opening to the ocean or a larger body of water. They are typically formed through erosion and can vary in size and shape. Bays are often characterized by calm waters and can provide shelter for boats and ships. They are also important habitats for various marine species.
3.
Which of these landforms is not a submerged feature?
Correct Answer
A. Peninsulas
Explanation
Peninsulas are not submerged features because they are landforms that extend into a body of water but are still connected to the mainland. They are formed by erosion and deposition of sediment over time. In contrast, ocean basins, mid-ocean ridges, and volcanoes are all submerged features. Ocean basins are large depressions on the Earth's surface that are filled with water, mid-ocean ridges are underwater mountain ranges formed by tectonic plate activity, and volcanoes are formed when molten rock erupts onto the Earth's surface.
4.
Which of these landforms is characterized by elevations?
Correct Answer
A. Plateau
Explanation
A plateau is a landform characterized by elevated and flat terrain, usually with steep sides. It is a large, flat area of land that is higher than the surrounding land. Plateaus are formed by geological forces such as tectonic activity or volcanic eruptions. They can be found in various parts of the world and are often used for agriculture or as natural barriers. Unlike valleys, bays, and canyons, plateaus are known for their high elevation.
5.
Which of these is not an attribute on which the classification of landforms is based?
Correct Answer
D. Development
Explanation
The classification of landforms is based on various attributes such as elevation, stratification, and soil type. However, development is not an attribute on which the classification of landforms is based. Development refers to human-made changes or alterations to the land, such as construction or urbanization, which are not inherent characteristics of landforms themselves. Therefore, development does not play a role in classifying landforms.
6.
What is the study of terrain called?
Correct Answer
B. TopograpHy
Explanation
Topography is the correct answer because it refers to the study and mapping of the physical features of a terrain, including its elevation, slope, and landforms. It involves analyzing and representing the surface characteristics of a landscape, such as mountains, valleys, rivers, and forests. Topography is essential in various fields, including engineering, urban planning, and geology, as it provides crucial information about the land's suitability for construction, resource exploration, and environmental management.
7.
What form of chemical weathering involves the attachment of hydrogen and hydroxyl ions?
Correct Answer
B. Mineral hydration
Explanation
Mineral hydration involves the attachment of hydrogen and hydroxyl ions to minerals. This process occurs when water molecules react with minerals, causing them to absorb water and undergo chemical changes. The hydrogen and hydroxyl ions from water molecules attach to the mineral's structure, altering its composition and potentially leading to the formation of new minerals. This process is a form of chemical weathering that can contribute to the breakdown and alteration of rocks and minerals over time.
8.
Which of these is associated with underwater relief?
Correct Answer
B. Bathymetry
Explanation
Bathymetry is the correct answer because it refers to the measurement and mapping of the underwater topography, including the depth of the ocean floor and the underwater relief features such as mountains, valleys, and ridges. It helps in understanding the physical characteristics and geological formations of the underwater environment.
9.
What is the study of landforms called?
Correct Answer
C. GeomorpHology
Explanation
Geomorphology is the study of landforms, their origin, evolution, and the processes that shape them. It focuses on understanding the physical features of the Earth's surface, such as mountains, valleys, plains, and rivers. Geomorphologists analyze the forces of nature, such as weathering, erosion, and tectonic activity, to explain how landforms are formed and changed over time. This field of study is essential for understanding the Earth's surface and its impact on human activities, including urban planning, natural resource management, and environmental conservation.
10.
Which of these is not a geographic feature?
Correct Answer
A. Canals
Explanation
Canals are man-made waterways created for navigation, irrigation, or water supply purposes. They are not naturally occurring geographic features like grasslands, deserts, or islands. Canals are constructed by humans to connect rivers, lakes, or seas and are not naturally formed by geological or environmental processes.
