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.
Answer: Sixty percent of all active volcanoes occur at the boundaries between tectonic plates most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean some volcanoes like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots
Answer:
D. divergent oceanic-oceanic boundary
Explanation:
- The oceanic and oceanic divergent plate boundary is a plate boundary were in the two oceanic plates moves away from each other and is an example of the mid-oceanic ridges in the mid-Atlantic ocean,
- Due to the cooling of the magmas on both the sides and the spreading of the seafloor as a result of this. This zone is the place of the construction of the new sea surface and does not show volcanism.
