Answer 1

Answer:

Groins, which are built to maintain or widen beaches, are barriers built at a right angle to the beach. Groins unfortunately cause longshore currents to erode sand from the beach on their downcurrent sides.

Seawalls are built to reflect the forces of unspent waves on the seaward side. Unfortunately, seawalls cause erosion of the beach on the seaward side.

Explanation:

Hard Stabilization is the term given to structures built in the beaches with the objective of blocking the force of the waves, preventing them from invading sensitized places, urban places and, mainly, places where they can cause erosion. These structures can be groins, which are established at right angles to the beach, but cause greater erosion of the areas on the side of the current, and seawalls that are built to prevent the passage of waves and decrease their strength, but increase the risks of erosion of the beach beside the sea.

Explanation:

They could also use energy more efficiently, they could instal renewables which are like solar and wind, they could use energy that is clos to wherever they are instead of using one thats way far away

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.

For many years, scientists thought that the ocean floor was flat. During World War II, U.S. Navy ships patrolled the oceans. A captain of one of the ships, Harry Hess, was also a geologist. He used a new device called an echo sounder to map the ocean floor. The echo sounder data showed that the ocean floor had mountains and volcanoes in addition to flat areas.
When scientists took samples of the rocks that made up the ocean floor, they discovered something surprising. The rocks closer to the mid-ocean ridge were younger in age than the rocks far away from the mid-ocean ridge. They concluded that this difference in age was another way to support the theory of plate tectonics.

Which best describes how the scientists could explain their observations?

A They thought that sediment washing in from the shore formed the

ocean floor, and continued to build out from the shore.

B They thought that strong ocean waves pushed the younger rock material toward the middle of the ocean

C They thought that wave erosion at the shore removed the younger rock layers that were on top of the older rock layers.

2. Name TWO types of rain clouds.​

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.

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.
