Question 1

Which of these is NOT a landform?&#10;A) a hill&#10;B) a mountain&#10;C) a sinkhole&#10;D) the Rocky Mountains

Accepted Answer

The Rocky Mountains is a collection of mountains, not a single landform.

Question 2

Topography that can be distinguished and studied as a single unit is a:&#10;A) landform&#10;B) tectonic environment&#10;C) landscape&#10;D) Karst topography

Accepted Answer

A landform is a specific topographical feature that can be distinguished and studied as a single unit, such as a mountain or valley. A tectonic environment refers to the geologic processes and features that shape the Earth's crust, and is not necessarily a single unit that can be studied as a whole. A landscape is a broader term that encompasses multiple landforms and other natural or human-made features within a given area. Karst topography refers specifically to landscapes formed by the dissolution of soluble rocks, such as limestone, and is therefore a subset of landforms rather than a general term for any distinguishable topography.

Question 3

_____ is a natural geologic process that breaks down rock.&#10;A) Erosion&#10;B) Weathering&#10;C) Mass movement&#10;D) Explosion

Accepted Answer

Weathering is the natural process of breaking down rock into smaller pieces through chemical, physical or biological agents without changing the rock's chemical composition. Erosion refers to the process of the removal and transportation of those smaller pieces by natural agents such as wind, water or ice. Mass movement refers to the down-slope movement of material under the influence of gravity. Explosion is not a natural geologic process.

Question 4

Smaller materials can be transported from one location to another by _____ processes.&#10;A) erosional&#10;B) weathering&#10;C) mass transit&#10;D) dislocation

Accepted Answer

Erosional processes, such as wind, water, and ice, can transport small particles such as sand, silt, and clay from one location to another. Weathering refers to the breakdown of rock into smaller particles, but it does not involve transportation. Mass transit typically refers to human transportation systems such as buses and trains. Dislocation is not a term commonly used in the context of material transport.

Question 5

As landscapes become steeper, these processes work more quickly to wear down the landscapes:&#10;A) erosional&#10;B) depositional&#10;C) freezing&#10;D) evaporation

Accepted Answer

Erosional processes, such as water and wind erosion, work more quickly on steeper landscapes because gravity pulls the material downhill faster, increasing the force of the erosion. Depositional processes, such as sedimentation, may also occur on steep landscapes, but do not necessarily work more quickly. Freezing and evaporation may contribute to erosion and weathering, but they are not primary erosional processes.

Question 6

All of the following are erosional agents in shaping the landscape EXCEPT:&#10;A) running water&#10;B) wind&#10;C) glaciers&#10;D) volcanic eruptions

Accepted Answer

Volcanic eruptions are not erosional agents, but they are depositional agents as they can add new volcanic materials to the existing landscape. Running water, wind, and glaciers are all erosional agents that can shape the landscape over time.

Question 7

The Canadian Shield region of the Great Lakes has been extensively eroded by:&#10;A) running water&#10;B) wind&#10;C) glaciers&#10;D) coastal waves

Accepted Answer

The Canadian Shield region of the Great Lakes was extensively eroded by glaciers during the last ice age. This resulted in the creation of the Great Lakes, which were formed by the melting of the glaciers and the subsequent filling of the depressions left behind. Running water, wind, and coastal waves have also played a role in shaping the landscape of the Great Lakes region, but they are not the primary cause of the extensive erosion.

Question 8

Areas of high relief tend to have:&#10;A) steep slopes&#10;B) high rates of erosion&#10;C) low rates of erosion&#10;D) both (a) and (b)

Accepted Answer

Areas of high relief, also known as mountainous regions, have steep slopes due to tectonic activity or erosion over time. The steepness of the slopes contributes to the high rates of erosion as water and gravity act to move material downhill. Therefore, both (a) steep slopes and (b) high rates of erosion are characteristics of areas with high relief.

Question 9

Volcanic remnants like Shiprock, NM are much smaller than the volcanoes of the Cascade Mountains because they:&#10;A) have been dormant and erosion has worn away most of its mass&#10;B) are still active and lose much of their mass through eruptions&#10;C) were originally quite small features&#10;D) are young features and haven't had time to grow

Accepted Answer

Volcanic remnants like Shiprock, NM have been dormant for a long time and have experienced significant erosion, which has worn away much of their mass. This is why they are much smaller than the volcanoes of the Cascade Mountains.

Question 10

The most important force driving erosion and transportation of eroded rock material into a new site of deposition is:&#10;A) running water&#10;B) Earth's gravity&#10;C) atmospheric wind&#10;D) alpine and continental glaciers

Accepted Answer

Earth's gravity is the most important force driving erosion and transportation of eroded rock material into a new site of deposition. Running water, atmospheric wind, and glaciers are all agents of erosion, but they all rely on gravity to move the eroded material.

Question 11
