Why can high-gradient streams move large sediment particles?
- A.
Because high-gradient streams can exert large forces on the stream bed.
- B.
Because it makes the stream flow go faster.
- C.
Because it can make cupcakes.
- D.
Because of downcutting.
- E.
None of the above.
Correct Answer
A. Because high-gradient streams can exert large forces on the stream bed.Explanation
High-gradient streams have steep slopes, which means there is a greater amount of energy and force exerted on the stream bed. This increased force allows the streams to move larger sediment particles. The force of the water flow can dislodge and transport larger rocks and sediments, resulting in the ability to move larger particles compared to low-gradient streams.Rate this question:

What is stream discharge?
- A.
Erosion of a valley by a stream.
- B.
The area of a river valley next to the channel, which is built of deposited sediments and is covered with water when the river overflows its banks at flood stage.
- C.
The volume of water passing a point along the river in a unit of time.
- D.
A term used for a small stream.
- E.
None of the above
Correct Answer
C. The volume of water passing a point along the river in a unit of time.Explanation
Stream discharge refers to the volume of water that flows past a specific point along a river in a given unit of time. It is a measure of the amount of water that a river carries and is an important factor in understanding the behavior and characteristics of a river. By measuring stream discharge, scientists and engineers can assess the water availability, predict floods, and manage water resources effectively.Rate this question:

How does stream discharge change from high-gradient streams to low-gradient streams?
Correct Answer
The gradient gets smaller
The gradient decreases
The slope decreases
The slope gets smaller
It get smallerExplanation
As streams transition from high-gradient to low-gradient, there is a decrease in the slope or gradient of the stream. This means that the stream becomes less steep, resulting in a smaller gradient. Additionally, the slope of the stream decreases, indicating a decrease in the steepness of the streambed. Therefore, the stream discharge changes from high-gradient streams to low-gradient streams by getting smaller or decreasing.Rate this question:

Why do high-gradient streams cause downcutting of their valleys?
- A.
None of the Below
- B.
Because since high-gradient streams cut their valleys vertically downward, they go too rapidly to widen out to form floodplains.
- C.
Because since high-gradient streams can exert large forces on the stream bed, they tend to erode their valleys rapidly.
- D.
Both B & C
- E.
None of the Above
Correct Answer
C. Because since high-gradient streams can exert large forces on the stream bed, they tend to erode their valleys rapidly.Explanation
High-gradient streams cause downcutting of their valleys because they can exert large forces on the stream bed, leading to rapid erosion of the valleys. This erosion occurs vertically downward, preventing the streams from widening out to form floodplains. Therefore, the correct answer is that high-gradient streams can exert large forces on the stream bed, causing rapid erosion of their valleys.Rate this question:

- E.
River Water, Vapor in atmosphere, Groundwater, Lakes/Reservoirs, Ice Sheets/Glaciers, Soil Moisture
Correct Answer
A. Ice Sheets/Glaciers, Groundwater, Lakes/ Reservoirs, Soil Moisture, Vapor in atmosphere, River WaterExplanation
The correct order of the water systems is Ice Sheets/Glaciers, Groundwater, Lakes/Reservoirs, Soil Moisture, Vapor in atmosphere, River Water. This order represents the natural flow and distribution of water in the environment. Ice sheets and glaciers store a large amount of water in the form of ice. Groundwater is the water that is stored underground in aquifers. Lakes and reservoirs hold water on the surface. Soil moisture refers to the water held in the soil. Vapor in the atmosphere represents the water that has evaporated and is present in the air. River water is the water that flows in rivers and streams.Rate this question:

As discharge ___________, the width, depth & velocity ___________.
- A.
Increases;increases
- B.
Decreases;decreases
- C.
Increases;decreases
- D.
Decreases;increases
- E.
Increases;stay the same
Correct Answer
A. Increases;increasesExplanation
As discharge increases, the width, depth, and velocity also increase. This is because as the amount of water flowing through a channel increases, it causes the channel to widen and deepen to accommodate the higher volume of water. Additionally, the increased flow of water also leads to an increase in velocity, as the water is forced to move faster to maintain the same discharge rate.Rate this question:

The gradient is steeper near the _______.
- A.
Head
- B.
Legs
- C.
Runoff
- D.
Mouth
- E.
Branch
Correct Answer
D. MouthExplanation
The gradient refers to the slope or steepness of a particular area. In this context, the question is asking where the gradient is steeper. The correct answer, "Mouth," suggests that the gradient is steeper near the mouth of a river or any other body of water. This is because as water flows downstream towards the mouth, it tends to pick up speed and erode the land more rapidly, resulting in a steeper gradient.Rate this question:

What causes stream discharge to change over time?
- A.
The gradient gets higher
- B.
The amount of time
- C.
The velocity of the stream flow
- D.
The large particles in the stream.
Correct Answer
C. The velocity of the stream flowExplanation
The velocity of the stream flow is the correct answer because it directly affects the stream discharge. As the velocity of the stream flow increases, more water is able to pass through a given point in the stream per unit of time, resulting in an increase in stream discharge. Conversely, if the velocity decreases, less water will pass through the same point in the stream, resulting in a decrease in stream discharge. Therefore, changes in the velocity of the stream flow can cause stream discharge to change over time.Rate this question:

Why do low-gradient streams have a broad flood plain?
- A.
None of the Below.
- B.
Because they shift sides through the meandering.
- C.
Because of the amount of sediment in aquifer
- D.
IDK
Correct Answer
B. Because they shift sides through the meandering.Explanation
Low-gradient streams have a broad floodplain because they shift sides through meandering. Meandering refers to the winding and curving path that a stream takes, causing it to constantly shift from one side of the floodplain to the other. As the stream meanders, it erodes the outer banks and deposits sediment on the inner banks, creating a wider floodplain. This shifting process over time results in a broad floodplain for low-gradient streams.Rate this question:

What types of sediment are carried and deposited by low-gradient streams?
- A.
Sand & Silt
- B.
Silt & Clay
- C.
All of the above
- D.
None of the aBOVE
Correct Answer
C. All of the aboveExplanation
Low-gradient streams typically carry and deposit a variety of sediment types, including sand, silt, and clay. The slow-moving water in these streams does not have enough energy to transport larger particles like gravel, so it primarily transports and deposits finer particles. Sand, silt, and clay are all common types of sediment found in low-gradient streams due to their smaller size and lighter weight, which allows them to be easily transported by the slow-moving water. Therefore, the correct answer is "All of the above."Rate this question:

- D.
When the stream channel can not contain the discharge & water that is passing through it.
- E.
The amount of stream flow downward in a high-gradient stream.
Correct Answer
D. When the stream channel can not contain the discharge & water that is passing through it.Explanation
Low-gradient streams flood when the stream channel is unable to contain the discharge and water that is passing through it. This can occur when there is a high volume of water flowing in the stream, such as during heavy rainfall or snowmelt. The low-gradient nature of the stream means that the water is not able to flow quickly downstream, causing it to overflow its banks and flood the surrounding area.Rate this question:

In a water table, what goes on top?
- A.
Zone of aeration
- B.
Zone of saturation
Correct Answer
A. Zone of aerationExplanation
In a water table, the zone of aeration is what goes on top. The zone of aeration is the area above the water table where the soil and rock are not saturated with water, but instead contain air and moisture. This zone allows for the movement of water through the soil and provides oxygen for plant roots. The zone of saturation, on the other hand, is the area below the water table where the soil and rock are completely saturated with water.Rate this question:
