U-shaped valleys and parallel grooves in bedrock are characteristics of erosion by
- A.
Mass movement
- B.
Wave action
- C.
Running water
- D.
Glacial ice
Correct Answer
D. Glacial iceExplanation
U-shaped valleys and parallel grooves in bedrock are characteristics of erosion by glacial ice. Glacial ice is a powerful force that can carve out valleys and create distinct features in the landscape. As glaciers move downhill, they scrape and grind against the bedrock, shaping it into a U-shape. The parallel grooves, also known as striations, are formed by the rocks and debris embedded in the ice, scratching the bedrock as the glacier moves. These features are unique to glacial erosion and provide evidence of past glaciation in an area.Rate this question:

What elevation and bedrock structure are generally found in the Catskills?
- A.
Low elevation and horizontal sedimentary bedrock structure
- B.
High elevation and horizontal sedimentary bedrock structure
- C.
Low elevation and folded metamorphic bedrock structure
- D.
High elevation and folded metamorphic bedrock structure
Correct Answer
B. High elevation and horizontal sedimentary bedrock structureExplanation
The Catskills are generally known for their high elevation, with peaks reaching over 4,000 feet. In terms of bedrock structure, the Catskills are predominantly composed of horizontal sedimentary rocks. This means that the layers of rock were originally deposited horizontally and have not been significantly folded or tilted. This combination of high elevation and horizontal sedimentary bedrock structure is characteristic of the Catskills.Rate this question:

Base your answers to this question on the diagram of the water cycle below. Letter A represents a process in the water cycle. Points X and Y represent locations on Earth’s surface. The process represented by A is
- A.
Precipitation
- B.
Transpiration
- C.
Condensation
- D.
Saturation
Correct Answer
B. TranspirationExplanation
The process represented by A is transpiration. Transpiration is the process in which plants release water vapor into the atmosphere through their leaves. In the water cycle, transpiration is an important component as it contributes to the overall movement of water from the Earth's surface to the atmosphere. This process helps in regulating the moisture levels in the atmosphere and plays a role in the formation of clouds and precipitation.Rate this question:

Base your answers to this question on the diagram of the water cycle below. Letter A represents a process in the water cycle. Points X and Y represent locations on Earth’s surface. Rainwater will enter the ground at X if the ground is
- A.
Saturated and permeable
- B.
Saturated and impermeable
- C.
Unsaturated and permeable
- D.
Unsaturated and impermeable
Correct Answer
C. Unsaturated and permeableExplanation
In order for rainwater to enter the ground at location X, the ground must be unsaturated, meaning it is not already filled with water. Additionally, the ground must be permeable, meaning it allows water to pass through it. If the ground is saturated, it is already filled with water and cannot absorb any more. If the ground is impermeable, it does not allow water to pass through it, so the rainwater would not be able to enter the ground. Therefore, the correct answer is unsaturated and permeable.Rate this question:

Base your answers to this question on the diagram of the water cycle below. Letter A represents a process in the water cycle. Points X and Y represent locations on Earth’s surface. The amount of runoff at Y will increase as the
- A.
Slope of the land decreases
- B.
Porosity of the soil increases
- C.
Evaporation rate exceeds the infiltration rate
- D.
Precipitation rate exceeds the infiltration rate
Correct Answer
A. Slope of the land decreasesExplanation
As the slope of the land decreases, the amount of runoff at location Y will increase. This is because a lower slope means that there is less gravitational force pulling the water downhill, allowing more water to accumulate and flow as runoff instead of being absorbed by the soil.Rate this question:

What is the minimum water velocity needed in a stream to maintain the transportation of the smallest boulder?
- A.
100 cm/sec
- B.
200 cm/sec
- C.
300 cm/sec
- D.
500 cm/sec
Correct Answer
B. 200 cm/secExplanation
The minimum water velocity needed in a stream to maintain the transportation of the smallest boulder is 200 cm/sec. This means that the water needs to flow at a speed of at least 200 cm per second in order to carry the smallest boulder. If the water velocity is lower than this, it will not have enough force to move the boulder downstream.Rate this question:
