Volcanoes are not randomly distributed over the Earth's surface. Most are concentrated on the edges of continents, along island chains, or beneath the sea forming long mountain ranges.
Answer:
Coal: 7.4 billion tonnes
Explanation:
The World Coal Association estimates that there are more than one trillion tonnes of coal reserves worldwide, enough to last 150 years at current rates of production, so it is unsurprising to see coal ranked as the most-mined mineral in the world.
While China has consistently led the world in production – the country was responsible for 3.3 billion tonnes in 2016 – this was down 16% from the 3.9 billion tonnes produced in 2012. Chinese coal output slumped below the 3.4 billion tonne-threshold predicted in 2016 and the trend may continue, as renewable energy sources become more widespread.
The Chinese decline has mirrored a trend in worldwide coal production, which fell to 7.4 billion tonnes in 2016 from 8.2 billion in 2012. While coal production has increased in Australia and Russia in the last five years, both South Africa and the US have seen sharp declines in production of anthracite and bituminous coal. American coal production in particular has fallen from over 900 million tonnes in 2012 to 782 million in 2016, the lowest figure since 1979.

(D) They are rare as they are found deep in the ocean they are very dangerous when they do go off though like the san andreas fault which was where one transform plate boundary earthquake went off killed over 600 people, that gets rid of B and A, and they were even erupting over 10 million years ago which gets rid of C and gives you the answer D.
The percent illuminated during the cresent phases is between 0 and 50%.
Answer:
1) Mercator Projection
2)the middle part of the grid
3)They are the same map of the world but different because the Robinson Projection youd have a globe, the other one is not a globe it looks to be a flat map.
