| Rocks which have solidified directly
from molten materials are called igneous rocks. Igneous rocks are commonly
referred to as primary rocks because they are the original source of material
found in sedimentaries and metamorphics. Igneous rocks compose the greater part
of the earth’s crust, but they are generally covered at the surface by a
relatively thin layer of sedimentary or metamorphic rocks. Igneous rocks are
distinguished by the following characteristics: (1) they contain no fossils; (2)
they have no regular arrangement of layers; and (3) they are nearly always made
up of crystals. Sedimentary rocks are composed largely of minute fragments derived from the disintegration of existing rocks and in some instances from the remains of animals. As sediments are transported, individual fragments are assorted according to size. Distinct layers of such sed A. Granite. B. Shale. C. Slate. D. Limestone.
