which of the following is a negative impact that flooding can have on the environment?
reduction of microbial populations
damage to infrastructure
distribution of organic material
recharging of groundwater

Damage to infrastructure

Explanation:

The flooding has some of the positive effects on the environment and also have some negative impacts on the environment.

When a huge amount of water from a certain source disturbs the mankind and environment is known as flood. It is so intense that it affects the buildings,  bridges, shops and building.

It carries the materials away with it to the places where it moves further. Damage to the infrastructure is one of the after effects of flood.

1)

Q: When creating an urban green space, which of the following needs to be determined in order for the space to provide the most benefit to the most people?

A: the proximity of the space to the city's population

2)

Q: Drag each phrase to indicate which flood mitigation technique it describes.

A: floodplain management: (protects buildings in low-lying areas prone to floods)

stormwater management: (enhanced by the addition of urban green spaces, reduces water runoff into streets lawns and other sites)

elevated structures: (raises structures above flood level, used mainly on the coast

3)

Q: Drag each phrase describing flood mitigation projects to the appropriate box to indicate whether it is a cost or a benefit.

A: cost: (ongoing maintenance, initial design and construction)

benefit: (lower insurance costs, employment opportunities, protection of infrastructure)

4)

Q: Drag each sustainable farming practice to indicate whether it is best suited for the desert, the rain forest, or mountains.

A: desert:(green houses, hydroponics)

rain forest:(alley cropping)

mountains:(terrace farming)

5)

Q: Which of the following is a negative impact that flooding can have on the environment?

A: reduction of microbial populations

6)

Q: How do green roofs compare to traditional roofs?

A: Green roofs initially cost more to install.

7)

Q: Drag each phrase into the correct column for the beach erosion strategy it describes.

A: jetty:(hard structure built perpendicular to shore, can cause sand buildup on updrift side of structure)

beach nourishment:(brings in more sand to replace erosion)

seawall:(hard structure that also provides flood protection, prevents erosion by directing waves back to ocean)

8)

Q: Why is beach nourishment considered mostly a short-term strategy for fighting beach erosion?

A: It must be repeated every 5 to 7 years.

9)

Q:Drag each effect of agroforestry in the rain forest to indicate whether it is a cost or a benefit.

A: Costs: (higher start-up expenses, increased need for labor)

Benefits: (higher amount of carbon storage, higher amount of nitrogen in the soil, increased numbers of pollinating insects)

10)

Q:What effects can erosion have on a beach? Select the two correct answers.

A: It can cause lower beach elevations. & It can cause narrower beaches.

hope this helps yall

if u can... pls give brainliest

good luck yall!

rain is the best answer

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
