One of the best advantages of coal as an energy source is:

1.   ?    it is common and therefore cheap
2.   ?    it is clean to use
3.   ?    it does not cause major harm to the environment
4.   ?    it is easy to transport

The best quality coal found in NZ is called

1.   ?    Peat
2.   ?    Lignite
3.   ?    Bituminous
4.   ?    Anthracite

Good quality coal tends to be:

1.   ?    very old with little water
2.   ?    very old with lots of water
3.   ?    relatively young with little water
4.   ?    relatively young with lots of water

The main coal mining region in terms of output is:

1.   ?    Southland
2.   ?    West Coast
3.   ?    Canterbury
4.   ?    Waikato

The oldest coal in NZ was formed:

1.   ?    75 million years ago
2.   ?    50 million years ago
3.   ?    35 million years ago
4.   ?    20 million years ago

The most important reason that determines whether to mine coal is:

1.   ?    the quality of the coal present
2.   ?    the amount of coal present
3.   ?    the depth of the coal
4.   ?    the demand for the coal

Which of the following contain only natural reasons for mining?

1.   ?    Amount of coal, skills of miners and accessibility of seams
2.   ?    How fractured the seam is, quantity of coal and quality of coal
3.   ?    Depth of the coal, capital available and land ownership.
4.   ?    Unfractured seams, ease of transport and skills of miners

In the future, coal mining in NZ is likely to

1.   ?    increase as we find more coal reserves making it even cheaper
2.   ?    decrease as other forms of energy become more environmentally favoured
3.   ?    increase as oil reserves get more rare and expensive
4.   ?    decrease as our coal reserves are likely to run out soon

Most of the coal produced in NZ today is:

1.   ?    used to make steel
2.   ?    used to heat hospitals
3.   ?    used for domestic heating
4.   ?    used to produce electricity

The main market to which we export our coal is:

1.   ?    China
2.   ?    Australia
3.   ?    Japan
4.   ?    Thailand
