4. Word-building.
a) State to what part of speech the words belong and from what words they are formed. Translate them into Russian:
deformation; recombine; indirectly; difference; effectiveness; redeposition; invariably; uselessness; width; countless; replace; decompose; resolidified; harden; disappearance; instability; irregularity.
b) Fill in the blanks with the adjectives formed from underlined verbs or nouns:
-
Under the action of pressure and high temperature rocks change their composition and structure. One may say that the structure and composition of rocks are . . . .
-
Everybody understands that metamorphic rocks have been developed from earlier igneous and sedimentary rocks. It is quite . . . . that these changes take place in texture, in mineral composition and in structural features of rocks.
-
Soft rocks can break into pieces. They are . . . .
-
Rare metals are of great value. They are very . . . .
-
Rock pressure and temperature vary. The role of water in metamorphism is determined by four . . . . parameters.
