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.
Roal Amunsen was the first.
The process happens as the warm air is said to be less dense than that of the colder air. Another good example of convection current is wind.
