Answer:
Explanation:
i)<u> Ground survey:</u>
A simple ground based field survey with the investigators walking around the survey area might help locate the Colonial plantation house. An extension of this, is to manually dig test holes either randomly, or in a grid to help locate the house.
ii)<u> Radar survey:</u>
Using ground penetrating radars, a subsurface image of the region can be prepared. The lack of vegetation will help generate a clear image. This subsurface can help possibly pinpoint the exact location of the plantation house. Radar uses EM waves to determine the shape of objects based on the reflectivity of the object being imaged.
iii) <u>Resistivity:</u>
The resistivity of the ash bed will be different from the resistivity of the material used to build the house, and this difference in resistivity can be used in a resistivity survey to locate the house.
Explanation:
The Pacific Ring of Fire is named so because of it's known ring-shaped pattern of Volcanoes. This is all due in part to merging tectonic plates, all resulting in oceanic Volcanoes. It does deserve the name "Ring of Fire" Because of the fact that the volcanoes shoot out fire hot magma, and all of them are arranged in a ring shape around the tectonic plate boundaries.
I hope this helped!
