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.
A. cities would be correct
Perimeter is 46 because it is 8+16+6+4+12
To find the area split up the two shapes, the bigger one is 8 times 12 which is 96 then the second shape has an area of 4 times 6 which is 24, add those together and the area of the whole shape is 120.
Answer:
Salina
Explanation:
they accidentally came across it while mining for salt in 1859
The answer is - Lighter traffic through rush hours.
The traffic during rush hours is terrible, especially in the big cities, when millions of vehicles are on the streets and everything is blocked and slowed down, which understandably no one likes.
When driving on the side streets though, the traffic in the bigger streets becomes much more bearable and is much faster, so both the drivers that use the side streets benefit from being quicker and evading big traffic, and the ones that drive through the bigger venues have it easier because there's much less traffic and everything is sped up.
