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.
Answer:
It took climate change, fertile river valleys, domestication of crops and animals so that the hunter-gatherers became sedentary farmers.
Explanation:
Initially, all humans were hunter-gatherers. This was due to multiple reasons, with one the biggest one probably being the climate which was not enabling good conditions for the hunter-gatherers to transform their lifestyle. All other conditions needed were stopped because of the climate conditions, so humans had to do what they could to survive in those conditions.
About 10 years ago though the bad climate conditions ended, or rather the Ice Age ended. This resulted in a much warmer climate, which in turn created much more water bodies like rivers and lakes, much more vegetation, and they contributed to the creation of much more fertile soil.
With these conditions in place, the humans quickly saw that there is huge potential in some plants and animals, so they started to farm them, select the ones with the best characteristics, and gradually producing enough food for themselves. With the food problem solved, humans didn't have the need to wonder around all the time, so they started abandoning the hunter-gatherer lifestyle and started settling in one place.

It has been said that grandchildren, even in most cases fare well living with their grandparents, many face the risk of not only poverty circumstances but also face more psychological problems than those living with traditional two-parent families. Most of the negative circumstances that lead the children to leave with their grandparents are children with <span>adolescent parents or child maltreatment. </span>

Here's your answer!!
Explanation:
Tropical cyclones, also known as typhoons or hurricanes, are among the most destructive weather phenomena. They are intense circular storms that originate over warm tropical oceans, and have maximum sustained wind speeds exceeding 119 kilometres per hour and heavy rains.
