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
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.

Farming in India would suffer greatly if
Omonsoons are a threat to all nations of Asia and Africa
Othere were no monsoon seasons
O the country's mineral wealth were developed
Omonsoons have far reaching consequences on life in South Asia
Farming in India would suffer greatly if monsoons are a threat to all nations of Asia and Africa. The correct option is a.
The monsoon season in India, which is critical for Asia's third largest economy, is expected to be robust and healthy this year if there is no surprise El Nino phenomenon, according to India's top government weather binding on Wednesday. Monsoon rains, the lifeblood of India's $2.6 trillion farm-dependent economy, arrive around June 1 on the southern tip of Kerala state and leave the desert state of Rajasthan by September.
Because nearly half of India's farmland lacks irrigation, its 263 million farmers must wait for monsoon rains to plant crops such as rice, cane, maize, cotton and soybean.

where do we find drought prone region in south africa?
Answer:
Much of the Eastern Cape province in South Africa has been experiencing a severe drought since 2015. This drought has had major socio-economic effects particularly on the large impoverished rural population as well as on some urban areas where supplied water services have broken down in several cases.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.
D They thought the young rock formed at the mid-ocean ridge and pushed the older rock toward the shore
Answer:
D
Explanation:
They thought the young rock formed at the mid-ocean ridge and pushed the older rock toward the shore

Explanation:
Tornadoes are most likely to form between 3 p.m. and 9 p.m. is the only correct fact
The following statements about tornadoes are myths.
True: Tornadoes are more likely to hit trailer parks than other communities.False: Tornadoes' low air pressure often makes houses explode.False: Tornadoes are most likely to form between 3 p.m. and 9 p.m.False: A highway overpass is a good place to hide from a tornado.False: Tornadoes kill more people than any other weather event. (In the United States, extreme heat, hurricanes, and flooding actually cause more weather-related deaths than tornadoes.)Why does air rush into a tornado?Shear, or a swift change in wind speed and direction, can occur when warm, humid air near the surface meets cold, dry air at higher elevations. When two air masses collide, cold air sinks more forcefully than warm air because it is heavier. In response, heated air quickly rises from the earth.
Thus, the mentioned above statement correctly describes whether they are true or false.

Is England a Compact, Elongated, Prorupted, Perforated or Fragmented country?
Is Palestine a Compact, Elongated, Prorupted, Perforated or Fragmented country?
Answer:
• England = Compact
• Palestine = Fragmented
Explanation:
England is a compact country because the distance from the center to most of the country's borders are not significantly different when compared to each other. The United Kingdom on the other hand, is a fragmented state because Northern Island is on land that is separate from the rest of the UK.
As implied above, a fragmented state is one where all the areas of the countries are not linked directly. This is the case with Palestine as the West Bank and the Gaza strip are not directly linked but form part of Palestine.
The scale drawing of a porch is 8 inches wide by 12 inches long. If the actual porch is 12 feet wide, what is the length of the porch?
Answer:
The actual length of the porch is 18 feet.
Explanation:
Scale = [tex]\frac{length on drawing}{actual length}[/tex]
So that considering the width of the drawing and actual porch,
1 foot = 12 inches
12 feet = 12 x 12 inches
= 144 inches
scale = [tex]\frac{8}{144}[/tex]
= [tex]\frac{1}{18}[/tex]
Given that the length of the porch drawn is 12 inches, let the actual length of the porch be represented by x. Then the actual length can be determined by;
scale = [tex]\frac{length on drawing}{actual length}[/tex]
[tex]\frac{1}{18}[/tex] = [tex]\frac{12}{x}[/tex]
x = 12 x 18
= 216
x = 216 inches
But,
1 foot = 12 inches
216 inches = 18 feet
The actual length of the porch is 18 feet.
Answer:
18ft

Which arrow on the map points to an air mass moving toward a cold front
Answer:
High pressure areas will always push air into low pressure areas. this creates air movement. on the map you see color lines, some red, some blue. this represents the different temperatures of fronts be it cold or warm. so the arrow moving from a high pressure area toward a low pressure area that has blue lines around it is your answer.
Explanation:
The arrow that moves from a high pressure area toward a low pressure area which has blue lines is one that points to an air mass moving toward a cold front.
What does the High pressure areas do?From the High pressure areas, the air are pushed into low pressure areas which creates an air movement.
This is evident on the map as we can see color lines, some red, some blue that represents the different temperatures of fronts be it cold or warm.
However, the arrow that moves from a high pressure area toward a low pressure area which has blue lines is one that points to an air mass moving toward a cold front.

Which of the options below are correct descriptions of hard stabilization of beaches? Select all that apply. Which of the options below are correct descriptions of hard stabilization of beaches? Select all that apply. Groins, which are built in pairs at river entrances, aim to keep sand from depositing in the channel. Groins unfortunately cause longshore currents to erode sand from the beach on their downcurrent sides. Jetties, which are built in pairs at river entrances, aim to keep sand from depositing in the channel. An effect of jetties is the erosion of sand on their downcurrent sides and the deposition of sand on their upcurrent sides. Seawalls are built to reflect the forces of unspent waves on the seaward side. Unfortunately, seawalls cause erosion of the beach on the landward side. 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.
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.
