GRADE 9 Social Studies – INTERNAL LAND FORMING PROCESSES Quiz
1. Which process is responsible for the formation of landforms such as valleys and ridges?
Erosion is the process by which valleys and ridges are formed through the wearing away of rock and soil by natural forces such as water and wind.
2. What landform is typically formed as a result of volcanic activity?
Plateaus are typically formed as a result of volcanic activity when lava flows cover large areas and then cool to form a flat, elevated landform.
3. Which process involves the breaking down of rock into smaller fragments?
Weathering is the process by which rock is broken down into smaller fragments through exposure to elements such as water, wind, and temperature changes.
4. What type of internal land forming process results in the folding of rocks?
Folding of rocks occurs as a result of internal forces in the Earth's crust, causing layers of rock to bend and fold over time.
5. Which process is responsible for the formation of sinkholes?
Erosion can lead to the formation of sinkholes when underground rock, such as limestone, is dissolved by water, creating a depression in the surface.
6. What landform is typically formed by the accumulation of sediment at the mouth of a river?
Deltas are landforms that form at the mouth of a river where sediment carried by the river is deposited, creating a fan-shaped area of fertile land.
7. Which process involves the transportation of weathered rock and soil from one place to another?
Erosion involves the transportation of weathered rock and soil by natural forces such as water and wind, moving them from one place to another.
8. What type of internal land forming process results in the uplifting of land?
Uplift is the internal process by which land is raised or lifted, often resulting in the formation of mountains and other elevated landforms.
9. Which process is responsible for the formation of sand dunes?
Deposition is the process by which sediments are deposited in a new location, often resulting in the formation of sand dunes through the accumulation of wind-blown sand.
10. What landform is typically formed by the movement of glaciers?
Moraines are landforms that are typically formed by the movement of glaciers, which pick up and deposit rocks and debris as they flow, creating ridges of mixed material.
