I'm not really sure but if this helps great, if it doesn't I'm sorry

To reduce the negative impact caused by human activities on the river, it is necessary to think of solutions that promote sustainability and introduce new ways of disposing of waste produced by individuals and organizations.

How to promote sustainability?

It is essential that each individual is aware of his or her active role as a citizen, establishing simple attitudes that can generate positive impacts on the environment, such as recycling personal waste and using green transport.

Therefore, in addition to the correct disposal of urban waste, the use of alternative and renewable energies are also measures that must be implemented to promote the sustainability of rivers.

Both regional and flash floods result from the release of large quantities of precipitation and/or snow melt.

a. True
b. False

Answers

Answer: a. True

Explanation:

Both regional and flash floods are a result of the release of large quantities of precipitation and/or snow-melt.

Winter and spring rains combined with melting snow overfill river basins and flood the banks, triggering regional floods. Regional floods can also happen when there's lots of rain, which saturates the soil and allows runoff to flood into streams and rivers. A flash flood, also triggered by heavy rains, is a local flood, meaning that it occurs in a small geographical region.

The Department of Natural Resources (DNR) is planning a study to determine whether breakwaters help decrease erosion at a large lake. They divide the shoreline into 100-foot plots, installing some with breakwaters and some without. However, the east and west shorelines of this lake receive very different wave patterns due to the wind. The DNR suspects this will affect the responses to the breakwaters. Because of this, the DNR plans to treat each shoreline as a different group. This study is an example of

Answers

Answer:

This study is an example of a blocked design experiment.

Explanation:

Directly, we can say that a blocked design experiment is an experiment that has the object of study divided into blocks that are repeated throughout the experimental unit. In the experiment presented in the question above, we can recognize these blocks when the researcher decided to divide the coastline into 30-meter plots, installing some with breakwaters and others without. Each plot, in this case, is a block.

This type of experiment requires that all blocks are the same and be subjected to the same factors. This allows the researcher to have control of the entire experiment and obtain homogeneous results in each block. In the experiment shown above, we can see that this control has been impaired, since the coastlines to the east and west of the lake receive very different wave patterns due to the wind. This will prevent the blocks from having homogeneous results, since the action of the breakwaters will be affected differently in each block.

1. Briefly explain how the cloud type for any particular day can be determined.
2. Name TWO types of rain clouds.​

giving away brainlist

Answers

Explanation:

1. High clouds:-

a) Cirrus clouds :-

Cirrus clouds are white wispy clouds that stretch across the sky. By all accounts, cirrus clouds indicate fair weather in the immediate future.

b) Cirrostratus :-

Cirrostratus tend to be sheet-like and cover the whole sky. You can usually tend to see the sun or moon through them. Their pressence usually indicates moist weather within the next 12 - 24 hours.

c) Cirrocumulus :-

Cirrocumulus clouds tend to be large groupings of white streaks that are sometimes seemingly neatly aligned. In most climates these mean fair weather for the near future.

Cirrocumulus clouds tend to be large groupings of white streaks that are sometimes seemingly neatly aligned. In most climates these mean fair weather for the near future.However, in the tropics, these clouds may indicate an approaching tropical storm or hurricane (depending on the season).

2.Middle clouds :-

a) Altostratus :-

Altostratus are grey and/or blue clouds that cover the whole sky. They tend to indicate a storm some time in the very near future since they usually precede inclimate weather.

b) Altocumulus :-

Altocumulus are grayish-white clouds blanketing the entire sky. The tend to look like large fluffy sheets in which there is a lot of contrast between light and dark. Sun does not pass through them. If you see them in the morning, prepare for a thunderstorm in the afternoon.

3. Low clouds :-

a) Stratus :-

Stratus are low-lying solid clouds that are often formed when fog lifts off the ground. They obviously look like an elevated fog. Often they bring drizzle or light snow.

b) Stratocumulus :-

Stratocumulus are low-lying bumpy and grey clouds. They do not bring precipitation. They also do not cover the entire sky and tend to come in rows and patches.

c) Nimbostratus :-

Nimbostratus is your standard rain cloud. It is a large flat sheet of grey cloud with a little bit of differentiation. If you see these, chances are it's raining outside.

4.Clouds with vertical mobility:-

a) Cumulus:-

Cumulus clouds are your stereotypical white "cottonball" clouds. So long as the clouds remain low clumps floating across the sky, there will be fair weather. However, you need to keep an eye on these clouds because any vertical growth can indicate the start of a large storm.

b) Cumulonimbus :-

Cumulonimbus are cumulus clouds that have grown vertically into an anvil-like shape. The anvil tends to point in the direction the storm is moving. These clouds bring most dangerous weather such as rain, lightning, hail and tornadoes.

2. Two types of rain clouds : -

Nimbostratus and cumulonimbus clouds.

Discuss the stage of development of the hagibis cyclone

Answers

Answer:

Tropical disturbance, tropical depression, tropical storm, and full-fledged tropical cyclone.

Explanation:

There are four stages of development of the Hagibis cyclone i.e. tropical disturbance, tropical depression, tropical storm, and full-fledged tropical cyclone. In tropical disturbance, the birth of a hurricane occurs, having a slight circulation only around low pressure area. The tropical depression is a cyclone that has maximum surface winds of 38 mph or less than 38 mph. When the intensity of tropical depression increases, it turned into tropical storm having surface winds from 39 to 73 mph. Then it turn into tropical cyclone having surface winds of 150 mph to 200 mph.

The stages in development of Hagibis cyclone includes:
