IM NOT SMART I WISH I COULD HELP YOU.
Air masses have the properties of the land below it. Because of this, different temperature air masses colliding can cause high or low pressure. High pressure usually causes cool sunny days, low pressure usually causes warm cloudy/rainy days.
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.
Set up a proportion: Central Angle/360= arc length/ circumference where the central angle= 45 and circumference= 128 ft. After you cross multiply, you should find that the answer is 16ft which is A.
Answer:
air flows from land to water
Explanation:
a sea breeze occurs during the day
the water has a high pressure hence the air flows from water to sea
there is low pressure on the land hence it receives air from the sea
land heats faster than the sea during the day
