-It determines a year:The time taken by the earth to move
around the sun or complete its orbit is fixed at
365(1/4)days
-It causes chnage in seasons:Areas like the west /Nigeria

season while the north or temperate region might be in
winter or summer
-It causes varying day and night at different times of the

-Mantle(Mesophere)
-Core(Barysphere)
=====================================
(3a)
Igneous rocks are formed by the cooling and
solidification of molten magma ejected from the beneath
of the earth crust.The magma which results from high
temperature and pressure beneath the earth forces itself
(wap-baze.com) towards the earth's surface through
cracks.As the magma moves towards the surface it
comes in contact with lower temperature hence it cools
and solidifies to form igneous rocks
(3b)
-Mountains:Mountains are formed when rocks subjected
to contractic or compressional forces which are
chemical,physical or other factors
-Plateux:This is formed when rocks are subjected to
mass wasting or mass movement
-Plains:Rocks helps to form plains when sediments are
bedded or stratified
