SHORT ANSWER QUESTIONS
15.
{a}. Define the
term MINING.

process of obtaining
minerals from the
earth.
{b}.
Name the five
types of minerals.
ANSWER:
The chief minersl
types in the
World include GOLD, DIAMOND , COPPER
MINERAL ORE , IRON
AND STEEL , TIN , MICA , LEAD
,COAL, URANIUM ,SILVER , NITRATE ,ZINK ,
MANGANESE , NICKEL , CHROME ,
BAUXITE SODA ASH
and PHOSPHATES.
16. Mention
the three {3} major
methods of mining.
ANSWER There
are three major
mining methods, namely :--
{a}. Open cast
mining. {b}. Alluvial mining.
{c}. Underground{ Shaft} mining.:
{17}.Which are
the factors influencing
mineral exploitation ?
ANSWER:
Mineral
exploitation is largely
determined by the
following factors . {a}. The
value of the
minerals. {b}. The size of the
deposits.
{c}.The quality
of minerals. {d}. Transport cost. {e}. Labour
{f}. Methods
of extraction.
{18}.
What are
the problems facing
mining industry in
Tanzania ?
ANSWER: {a}. Lack of Capital
in poor countries has
limited the progress
of mining industry. For example
large reserves of
coal in Ruhuhu
and iron ore
in Ludewa district---Iringa region
in Tanzania remained
unexploited.
{b}. Lack of
skilled labour in
poor countries such
as those of
Sub-Saharan Africa led
to both poor
exploitation and yield.
{c}.Power rationing
like in Tanzania
is weakening the
efforts of developing
the sector.
{d}.Exhaustion of
mineral deposits due
to over exploitation
like Copper in Zambia.
{e}.Price fluctuation
in the World
market , which affects
the development of
mining industry.
{f}.Political strife
for example in
Congo D.R.C also
affects the smooth
exploitation of minerals.
{g}.Poor transport
system especially in
the developing countries
hinder exploration and
other important researches
on mining sector.
Example landlocked countries
like Zambia are
facing several problems.
