(2 a )
- 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 might have rainy
season while other areas have dry
season while the north or temperate
region might be in winter or summer
- It causes varying day and night at
different times of the year. The length of
day and night depend in the earth and it
position with the sun
- It causes changes in the attitude or
height of the sun result in equinox and
solstices
(2 b )
- Crust (Lithosphere )
- Mantle(Mesophere)
- Core (Barysphere )
=====================================
(3 a )
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 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
(3 b )
- 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
(3 c )
- Sources of minerals
- Sources of fuel
- Construction purposes
- Tourist centres
- Sources of food nutrient
=======================================

(4 b )
A type - Tropical rainy climates
B type - Dry climates
C type - Warm temperate rainy climate
(Humid mesothermal climates)
D type - Snowy and cold climates(cold
snow climates)
E type - Polar climates(ice climates)
======================================
(5 a )
- Focus : Is the point at which the shock
originates
- Epicenter: Is the point on the earth ' s
surface directly above the focus or
where the shock waves first hit the
surface
(5 b )
TABULATE
Earthquake br / > - It is the result of
disturbance or
movement within and below the earth ' s
crust

which molten rock
or magma is forced into the earth ' s crust
or surface
- It might occur in the earth surface
Similarities br / > - They are both
landform features

7 a )
- It is a source of food supply
- It is a source of firewood
- It prevents erosion
- It is a source of raw material for index
7 b )
- Transportation problem : It is very hard
to move goods and services from one
place to another due to bad weather and
others
- It causes soil erosion : Vegetative conver
tend to spoil the land and cause erosion
- High cost of exploitation : There is high
cost of production
- Depletion of natural forest products : It
limits the use of forest products and its
cultivation
- Flooding : The vegetative cover when
harvested spoils the land and can lead to
flooding
- Disappearance of wildlife: Many wild
animals live in the forest and cannot live
on a bare plain land
7 c )
- Improvement of infrastructures like
roads
- Planting cover of cover crops
- Curving down and subsidy to the
farmers
- Afforestation
- Encouragement of afforestation
7 d )
- Renewable resources are natural while
non renewable resources are man made
or artificial
- Renemable resources can be reversed
while non renewable cannot
- Renewable resources cannot be
exhausted while non renewable
resources can be exhausted
