Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains.
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:
Islam made its way to India between 700 and 800 CE.
Explanation:
India, as a region, is the cradle of Hinduism, Buddhism, and Sikhism. Hinduism has become and remained dominant, with Sikhism being practiced on a smaller scale, while Buddhism moved eastward. Despite the dominance of Hinduism in the region, between 700 and 800 CE, a new religion came in and ever since has been competing with it.
The new religion in the region was Islam. Initially, it came with the traders and merchants, some of which settled in India and formed small communities. After that, the more important process of the introduction of Islam in India was through military conquest and forced conversion. This has resulted in large areas of India that were ruled by Muslims quickly become dominated by Islam, and since Muslims were rulling areas of India for a very long time the influence was very big, where around a third of the total population of the region nowadays is Muslim.
