a)The earth experiences the force of gravity pulling towards the centre which
creates a rounding effect on its shape.
- The North and South poles experience centripetal force which constantly pull
towards each other causing the flattening at the poles.
- At the equator the earth experiences the centrifugal force which causesthe
bulge.
Force 1 x 2 = 2
Shape 1 x 2 = 2
NB: F can score on its own. “S’ must be tied to “F” to score.
b) State four effects of the rotation of the earth on its axis.
- It causesthe occurrence of day and night /apparent movement of the sun from
East to West.
- It causes difference in time between places over the earth’s surface.
- It causes deflection of winds / ocean currents.
- It causes differences in atmospheric pressure on the surface of the earth.
- It causes ocean/sea tides
