(a) Name three types of mountains and give a good example of each
(b) Describe the process of formation of any type of mountains
(c) In what four ways are mountains of great importance to man?.
Explanation
(a) Three types of mountains are:
(i) Block mountain e.g the Hunstruck mt. of Germany
(ii) Fold mountain e.g the Himalayas
(iii) Volcanic mountain, e.g Fuji mountain of Japan
(b) Mode of formation of Fold mountains
(i) Folding is caused by large stale h Drizontal earth movement
(ii) Stresses, caused by expansion or contraction of some parts of the earth, are set up in the earth’s crust
(iii) Such stresses subject the reeks to compressive forces
(iv) The compressive forces produce wrinkling or folding of the earth’s crust
(v) The upfold of the wrinkles are called anticlines while the downfold are synclines.
(c) Four ways in which mountains are of great importance to man;
(i) High mountain can result in the formation of rainfall i.e relief rainfall
(ii) Mountain serves as the source or origin of all rivers
(iii) Mountains are rich sources of minerals Stones found in mountains can be quarried for building construction
