(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.

Explanation

(a) (i)Percentage of unfertilized eggs

25 x 100

1500 1

= 1.67%

(ii)Percentage of fertilized eggs

No of fertilized eggs 1500 – 25

= 1475

Percentage of fertilized eggs

1475 x 100

1500 1

= 98.33%

(iii)Percentage of male chicks

475 x 100

1500 1

= 31.67%

(iv)Percentage of female chicks

No of female chicks = 1500 –25 – 475

= 1000 chicks

Percentage of female chicks

1000 x 100

1500 1

= 66.67%
