The basic concept of Uniformitarianism is ________.
nothing has changed since the earth was formed
geology has not changed since the earth was formed but other things do change
evolution, Plate Tectonics, and similar theories are all related and can be viewed as the grand theory of Uniformitarianism.

thinner than continental crust
a civil engineer
a geologist
a physicist
an astrologer
Explanation / Answer
answers :
1 ) a geologist
geologist will conduct seismic surveys to know the structures of rocks, like faults and joints present beneath the earth. if they were present then there might be a chance of having earthquakes
2) permineralization replacing original cellulose of the wood
the replacement of wood is mainly by the silica
