The behaviour of the river will change as the gradient does. A river has a straight, deep, and narrow channel. It is a river gradient.
Give a brief account on river gradient.A river's gradient is a gauge of how rapidly its height is lost. Typically fast-flowing and young, a river with a high gradient rapidly loses height. An extremely soft gradient causes very little height loss, and such a river is usually an older, slower-moving river. In fact, a stream in a lowland area may have a gradient that is so slight that it is hard to measure without specialized tools. As a result, it has a greater capacity to erode. In contrast, a low gradient suggests a stream bed that is more or less flat and slow-moving water that may only be able to carry minute amounts of very fine debris. High gradient streams are referred to as young streams because they frequently feature steep, narrow V-shaped troughs. Low gradient streams have larger, less rocky troughs and a propensity to meander. Many rivers entail, to some extent, a river gradient flattening as they go closer to the terminus at sea level.

1)How much can the US reduce CO2 emissions from coal from the current 48.9 C? Assume D:C ratios of 1.2 for coal, and 2.23 for natural gas.
(a) If we currently use 33.9 D for natural gas, and 11.9 D for coal, what would be the emissions in units of C by eliminating coal power plants with an energy efficiency of 32.2% to natural gas plants with an efficiency of 43.1%?
(b) What would be the change in C if the gas plants were 65% efficient?
2) If a coal plant with an efficiency of 32.6% (Dff:C = 1.2) is replaced by a natural gas plant that produces the same amount of electricity but at an efficiency of 43.6% (Dff:C=2.23), what is the percentage of CO2 reduction? Consider both the reduction in CO2 for the energy in the fuel, and the relative efficiency of the plant.
(a)
To convert from units of D to units of C, we use the D:C ratio for coal, which is 1.2.
The current emissions in units of C from coal are 11.9 D / 1.2 = 9.92 C.
To find the emissions in C after the coal plant is replaced with the natural gas plant, we need to find the amount of natural gas needed to produce the same amount of electricity.
This can be done by dividing the energy produced by the coal plant by the efficiency of the natural gas plant, which is 43.1%:
11.9 D / 43.1% = 27.5 D
The emissions from the natural gas plant can then be calculated using the D:C ratio for natural gas, which is 2.23:
27.5 D * 2.23 = 61.5 C
The change in CO2 emissions can then be calculated as the difference between the current emissions from the coal plant and the emissions from the natural gas plant:
61.5 C - 9.92 C = 51.58 C
(b)
The amount of natural gas required to produce the same amount of electricity as the coal plant can be found using the same calculation as in (a):
11.9 D / 65% = 18.31 D
The emissions from the natural gas plant can then be calculated using the D:C ratio for natural gas, which is 2.23:
18.31 D * 2.23 = 40.75 C
The change in CO2 emissions can then be calculated as the difference between the current emissions from the coal plant and the emissions from the natural gas plant:
40.75 C - 9.92 C = 30.83 C
The amount of CO2 emissions produced per unit of energy can be found using the D:C ratios for the two plants:
For the coal plant, this is 1.2 C / 1 D.
For the natural gas plant, this is 2.23 C / 1 D.
The reduction in CO2 emissions can then be calculated as the difference in CO2 emissions per unit of energy between the two plants:
2.23 C / 1 D - 1.2 C / 1 D = 1.03 C / 1 D
The reduction in CO2 emissions can then be expressed as a percentage by dividing the reduction by the emissions from the coal plant and multiplying by 100%:
(1.03 C / 1 D) / (1.2 C / 1 D) * 100% = 86%

describe some of the challenges of data collection related to climate and environmental justice
One of the main challenges of data collection related to climate and environmental justice is the lack of reliable, up-to-date data sources. Additionally, it can be difficult to collect data from remote or rural areas where access to resources may be limited. Language barriers and cultural differences can also affect data collection, as can the fact that data may be collected over long periods of time, making it difficult to determine if the data is still relevant. Qualitative methods such as participant observation, in-depth interviews, and focus groups can be used to gain further insight into the data collected. Additionally, sustainable development pathways, supported by effective environmental management, can help mitigate the effects of climate and environmental injustice. To address the issue of corporate and governmental control of data, innovative measures such as carbon taxes can be designed to internalize environmental costs. Finally, nurses can conduct assessments during visits to patients in their homes and places of work to gain first-hand information about environmental factors that may be contributing to health disparities.

You date a rock using the Potassium-Argon system and find that it contains three times as much Argon-40 than Potassium-40. How old is the rock? -- 103933295
The exact age of the rock is not derivable from the information given, as additional information is required, such as the starting ratio of Potassium-40 and Argon-40, the rate of decay, and other factors that may affect the accuracy of the measurement.
How do we use rock dating to determine the rock age?Any method of determining the age of earth materials or organic objects based on the measurement of either short-lived radioactive elements or the amount of a long-lived radioactive element plus its decay product is referred to as rock dating.
The age of a rock using the Potassium-Argon system is determined by the ratio of Argon-40 to Potassium-40. If a rock contains three times as much Argon-40 as Potassium-40, it is possible to calculate the age of the rock by comparing the measured ratio to the known decay rate of Potassium-40 to Argon-40.
Generally, to determine the exact age of a rock using the Potassium-Argon system, it is necessary to perform a radiometric dating analysis in a laboratory, taking into account various variables that may affect the accuracy of the measurement.

Why is understanding the structure of the earth important
Understanding the structure of the earth is important because it allows us to understand and predict geological events such as earthquakes, volcanic eruptions, and tsunamis. It also helps us to understand the formation and movement of tectonic plates.
What do you mean by tectonic plates?
Tectonic plates are large sections of the Earth's crust that move independently of each other and interact with each other along their boundaries. Plates can interact in three different ways: constructively, destructively, and conservatively. Constructive boundaries create new lithosphere, while destructive boundaries consume lithosphere. Conservative boundaries neither create nor consume lithosphere, but instead cause plates to slide past each other. The boundaries of the plates are known as plate boundaries, which can be either divergent, convergent, or transform. Divergent plate boundaries form when two plates move away from each other, leading to the formation of new lithosphere from molten material. Convergent plate boundaries form when two plates collide, and can lead to the formation of mountains and oceanic trenches.
So, Understanding the structure of the earth is important because it allows us to understand and predict geological events such as earthquakes, volcanic eruptions, and tsunamis.

Two distinct landforms and depositional landforms are sea cliffs, sea caves, barrier island and sandbars.
What are examples of Distinct Landforms and Depositional Landform?Erosional landforms include
Sea Cliffs: A sea cliff is a steep, vertical or near-vertical rock face that is created by the action of waves, wind, and rain eroding the coastline. The waves break against the base of the cliff, causing chunks of rock and soil to break away and fall into the water. Over time, this process can result in cliffs that are hundreds of feet high.Sea Caves: A sea cave is a type of coastal cave that is formed by the action of waves eroding the shoreline. The waves break against the cave walls and floor, causing the rock and soil to break away and fall into the water. Over time, this process can result in caves that are large enough for people to exploreDepositional landforms includes:
Barrier Islands: A barrier island is a long, narrow island that is located offshore from the mainland. Barrier islands are created by the action of waves and currents that transport sediment from the mainland out to sea. Over time, the sediment accumulates and forms the island. Barrier islands are often covered in sand dunes and other vegetation, and they serve as important habitats for a variety of wildlife species.Sandbars: A sandbar is a type of depositional feature that is created by the accumulation of sand in shallow water near the shoreline. Sandbars can be created by waves, currents, and tidal action, which transport sediment from the shoreline out to sea and then deposit it in shallow water. Over time, the sediment accumulates and forms a sandbar that is visible above the water surface. Sandbars can change in size and shape over time as the sediment is transported and deposited elsewhere.Learn more about landforms here: https://brainly.com/question/28551341
