Levees are structures built around rivers to control and prevent flooding. In Louisiana, massive levees have been built around the Mississippi River. Prior to the levees being built, seasonal floods would deposit sediment rich in nutrients throughout the wetlands and floodplains in Louisiana. Now, the sediment is carried out to sea, and areas around the levees are rarely flooded.

What is a solution that reduces the impact of levees on the environment in Louisiana?

A
Redirect water in the continental U.S. to other rivers and coasts.
B
Increase the height of the levee's walls to prevent all possible flooding.
C
Divert, or distribute, river sediment from the state's coastal areas into wetlands.
D
Build levees that go further upstream on the Mississippi River.

Answers

A Levee is a characteristic or fake wall that blocks water from going where we do not believe it should go. It's choice C.

An answer that lessens the effect of levees on the climate in Louisiana is to Deflect, or circulate, stream dregs from the state's deep-water regions into washes.

The levees have kept sand front washes from getting the ordinary food of riverine water, supplements and residue that are introductory to deep-water swamp abidance.

Levees are constructed to alleviate flooding pitfalls; still, they don't fully exclude the threat. It's constantly conceivable that a flood tide will surpass the limit of a levee, anyhow of how well the construction is fabricated.

Compare and contrast the effects of warm and cold currents on climate

Answers

Answer:

The cold currents often form when the air on the subtropical high blows over a cold mass of water, then the cold air is dragged to the equator. Warm currents, on the other hand, are large masses of warm water moving further away from the equator, at higher temperatures.

Cold ocean currents move towards the equator which forms cold air and Warm currents, on the other hand, move away from the equator resulting in formation of hot or warm air.

How do warm and cold currents affect the climate?

The ocean currents act as thermal condensers, transmitting heat to tropical areas and helping tropical areas cool down, thus affecting both the weather and the climate.

Cold waves often form when hot air blows over cold water, and cold air is drawn into the equator.

Warm currents, on the other hand, are the warmest waters of the equator, at higher temperatures.

Thus, Cold ocean currents move towards the equator which forms cold air and Warm currents, on the other hand, move away from the equator resulting in formation of hot or warm air.

Explanation:

Culture encompasses many aspects of one's life including their language, traditions, beliefs, and even what they eat and wear.

All clouds form due to the warm, moist air __________ then getting to cooler elevations and cooling.

Answers

All clouds form due to the warm, moist air rises then getting to cooler elevations and cooling.

Processes of cooling

The warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. Eventually, enough moisture will condense out of the air to form a cloud. The air cools as it rises, and eventually clouds form.

Therefore, moist air rises then get to cooler elevations and cooling.

The future effects of global climate change could be devastating if we do not address it. Climate change will affect our weather patterns in the future. The future effects of global climate change will not be seen for hundreds of years.

Answers

The basic idea presented in this political cartoon is that if we do not handle global climate change, the consequences could be disastrous.

What happens if we don't address climate change?

Climate Change and Its Consequences are more frequent wildfires, prolonged drought periods in some locations, and an increase in the number, duration, and severity of tropical storms are all possible future implications of global climate change.

If we do nothing, heat waves will become more common and severe over the planet, harming hundreds of millions—if not billions—of people.

Therefore, option (b) or (ii) is the correct answer.
