Section B Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice. The Earth comprises three principal layers: the dense, iron-rich core, the mantle made of silicate(硅酸盐)that are semi-molten at depth, and the thin, solid-surface crust. There are two kinds of crust, a lower and denser oceanic crust and an upper, lighter continental crust found over only about 40 percent of the Earth's surface. The rocks of the crest are of very different ages. Some continental rocks are over 3,000 million years old, while those of the ocean floor are less than 200 million years old. The crusts and the top, solid part of the mantle, totaling about 70 to 100 kilometers in thickness, at present appear to consist of about 15 rigid plates, 7 of which are very large. These plates move over the semi-molten lower mantle to produce all of the major topographical(地形学的)features of the Earth. Active zones where intense deformation occurs are confined to the narrow, interconnecting boundaries of contact of the plates. There are three main types of zones of contact: spreading contacts where plates move apart, converging contacts where plates move towards each other, and transform. contacts where plates slide past each other. New oceanic crust is formed along one or more margins of each plate by material issuing from deeper layers of the Earth's crust, for example, by volcanic eruptions(爆发)of lava(火山熔岩)at mid-ocean ridges. If at such a spreading contact the two plates support continents, a rift(裂缝)is formed that will gradually widen and become flooded by the sea. The Atlantic Ocean formed like this as the American and Afro-European plates moved in opposite directions. When two plates carrying continents collide, the continental blocks, too light to be drawn down, continue to float and therefore buckle(起褶皱)to form. a mountain chain along the length of the margin of the plates. The Earth's crust ______.
A.
can be classified into two types
B.
is formed along the margins of the plates
C.
consists of semi-molten rocks
D.
is about 70 to 100 kilometers thick
