why does river damming sometimes contribute to coastal erosion

Answers

Answer 1

River damming is the process of building a barrier across a river to hold back the water and create a reservoir. This is often done for various reasons such as flood control, irrigation, and hydroelectric power generation. While the benefits of damming a river may be numerous, it can also have negative impacts on the surrounding environment.


One such impact is the contribution to coastal erosion. Rivers are a major source of sediment that is carried downstream and eventually deposited at the river's mouth where it meets the sea. When a river is dammed, the flow of sediment is disrupted, and the sediment is trapped behind the dam. This causes a decrease in sediment supply downstream, which can lead to erosion of the coast.
Coastal erosion occurs when the waves and currents of the sea wear away the land and remove the sediment that would normally replenish the coast. With the reduced sediment supply from the dammed river, the natural balance of sediment input and output is disrupted, leading to coastal erosion.
Furthermore, when dams are built, they often trap sediment, which can lead to increased erosion of the riverbanks and the riverbed downstream. This increased erosion can result in a decrease in water quality, habitat destruction, and the loss of valuable land.
In conclusion, while damming a river may have benefits, it can also contribute to coastal erosion. It is essential to consider the environmental impacts of damming a river before undertaking such a project. This involves proper planning and management to ensure that the natural balance of sediment supply is maintained and that downstream ecosystems are not negatively impacted.

will various soils high in organic matter always have a high level of microbiological activity. why or why not?

Answers

Answer:

Like all living things, soil microbes need access to nutrition and water and therefore tend to concentrate near sources of soil organic matter. Microbial biomass and diversity tend to be much higher in the soil immediately surrounding plant roots, an area known as the rhizosphere, and other organic matter deposits.

Explanation:

Various soils high in organic matter do not always have a high level of microbiological activity. While organic matter provides a potential source of energy and nutrients for microorganisms, several other factors influence microbiological activity in soils.

1. Environmental Conditions: Microorganisms require specific environmental conditions to thrive, including suitable moisture levels, temperature, pH, and oxygen availability. If these conditions are not optimal, microbial activity may be limited even in soils with high organic matter content.

2. Soil Texture and Structure: Soil texture and structure can affect microbial activity by influencing factors such as water holding capacity, aeration, and nutrient availability. Soils with poor structure or excessive compaction may limit microbial growth and activity, regardless of organic matter content.

3. Nutrient Balance: While organic matter provides a source of carbon and energy, microorganisms also require a balance of other nutrients such as nitrogen, phosphorus, and micronutrients for growth and activity. Soils with imbalanced nutrient levels or deficiencies may not support high microbiological activity, even with ample organic matter.

4. Toxic Substances: Certain substances, such as pollutants or high levels of salts or heavy metals, can inhibit microbial activity. Soils contaminated with such substances may have reduced microbiological activity despite high organic matter content.

List three examples of carbon reservoirs or stocks in cities, with a short explanation of why this is a carbon reservoir. At least one of the examples must be found
primarily in cities and not in non-human dominated ecosystems.

Answers

Buildings and Infrastructure: Buildings in cities act as carbon reservoirs due to the materials used in their construction, such as concrete and steel, which contain embedded carbon.

Additionally, buildings can contribute to carbon storage through the use of green infrastructure like green roofs or vertical gardens, which absorb and store carbon dioxide through plant photosynthesis.

Urban Forests: Urban forests, including trees and vegetation in cities, serve as carbon reservoirs. Trees absorb carbon dioxide during photosynthesis, storing carbon in their biomass. Urban forests play a crucial role in offsetting carbon emissions from human activities, helping to mitigate the urban heat island effect and improve air quality.

Landfills: Landfills in cities act as carbon reservoirs due to the decomposition of organic waste. When organic waste decomposes in anaerobic conditions, it produces methane, a potent greenhouse gas. Landfills capture and store methane, preventing its release into the atmosphere. Landfill gas capture systems can collect methane and use it for energy generation, reducing greenhouse gas emissions and utilizing a previously wasted resource.

These examples highlight how carbon reservoirs in cities can both contribute to carbon storage and help mitigate climate change by reducing carbon emissions or promoting carbon sequestration through urban greening initiatives and sustainable waste management practices.

what caused dust and condensing material to accrete into planetesimals

Answers

The process of accretion of dust and condensing material into planetesimals is primarily driven by gravitational forces, collisions, and other physical interactions in a protoplanetary disk.

Here are some key factors that contribute to this process:

Gravity: Particles in a protoplanetary disk are subject to gravitational attraction. As dust and condensing material accumulate, their collective gravitational pull becomes stronger, causing particles to be drawn together.

Collisions: Within the protoplanetary disk, particles collide with each other due to their relative motion. These collisions can lead to the sticking of particles, forming larger aggregates. Over time, these aggregates grow through further collisions, eventually reaching sizes where their own gravity becomes significant.

Van der Waals Forces: Van der Waals forces are weak intermolecular forces that can act between particles in close proximity. These forces can help particles stick together during collisions and promote the growth of larger aggregates.

Electromagnetic Forces: Charged particles in the protoplanetary disk experience electromagnetic forces. These forces can lead to the formation of electrostatic bonds between particles, aiding in their aggregation and eventual accretion.

Gas Drag: The presence of gas in the protoplanetary disk can have a significant effect on the motion of particles. Gas drag slows down the relative velocities of particles, allowing them to come closer together and facilitating their sticking and accretion.

Snowline: The snowline is a region in the protoplanetary disk where volatile substances, such as water and other ices, can condense. The presence of ices can enhance the sticking efficiency of particles, leading to the formation of larger bodies.

you have collected some samples while examining local rocks. you decide to have them analyzed at wsu using radiometric age dating. your analysis returns and says that 25% of the parent isotope remains in your rock samples. how many half lives have elapsed?

Answers

In order to answer this question, we first need to understand how radiometric age dating works. Radiometric age dating is a method used to determine the age of rocks and other materials based on the decay rate of radioactive isotopes.

The rate of decay is measured in half-lives, which is the amount of time it takes for half of the parent isotope to decay into the daughter isotope.
In this case, we are told that 25% of the parent isotope remains in the rock samples. This means that 75% of the parent isotope has decayed into the daughter isotope. To determine how many half-lives have elapsed, we need to use the following equation:
% remaining = (1/2)^(number of half-lives)
In this case, we can plug in 25% for % remaining and solve for the number of half-lives:
25% = (1/2)^(number of half-lives)
log(25%) = log((1/2)^(number of half-lives))
log(25%) = number of half-lives * log(1/2)
number of half-lives = log(25%)/log(1/2)
number of half-lives = 2.0
Therefore, we can conclude that two half-lives have elapsed. This information can be used to determine the age of the rock samples, assuming we know the half-life of the radioactive isotope being measured.

While some pilgrimage sites may provide opportunities for tourists to interact with the local community, this is not always the case. In many instances, the indigenous population may be largely excluded from the tourism experience, particularly if the pilgrimage site is located on lands that have been historically or culturally significant to the local population. This can be a source of tension, particularly if tourism development is seen as a threat to the preservation of indigenous traditions and cultural heritage. It is important for tourism planners and developers to be sensitive to the needs and concerns of the local community, and to work collaboratively with them to ensure that pilgrimage tourism benefits the indigenous population and helps to sustain their cultural and natural resources.

Spreading center volcanism most generally produces rocks that are ____________.
a. granitic in composition b. basaltic in composition
c. andesitic in composition d. ultramafic in composition

Answers

Spreading center volcanism most generally produces rocks that are B)basaltic in composition.

Basaltic rocks are a type of igneous rock that is formed from the solidification of magma or lava that is rich in iron and magnesium, and poor in silica. Spreading centers are divergent plate boundaries where two plates are moving away from each other, and magma from the mantle rises up to fill the gap between them, resulting in volcanic activity. The magma that erupts at spreading centers is generally basaltic in composition, which explains why the rocks produced by spreading center volcanism are also basaltic. Basaltic rocks can be found in a variety of settings, from oceanic islands to the ocean floor, and they can provide important clues about the geologic history and processes that have shaped our planet.
