Answer: Map scale can be defined as the relationship that can be drawn in between the length of the map and the length of the ground.

The unit of the length on the map and the corresponding length of the ground is the map scale. The type of map scales:
Large Scale 1:25,000 or more
Medium Scale 1:1,000,000 to 1:25,000
Small Scale 1:1,000,000 or less
Small scale and medium scale can demonstrate large area for example a country or state whereas the large scale can demonstrate a small area like a city or region of city.

Answer:
Coal it is formed when there is some heat and pressure conditions mixed together.
Explanation:
Depending the conditions are the stages of coal that are presented, the greater the pressure and heat, the higher rank appears (from peat, lignite, bituminous until anthracite).
During the Carboniferous period, in the Paleozoic Era, there were a collision among Laurasia (present day Europe, Asia and North America) with Gondwana (present day Africa), both part of the Pangea. As a result of the collision, Appalachian Mountain appears in North America and Hercynian Mountains in the UK. Giving a separation of both continents.
During this period, the mild temperatures, increases the tree ferns, plus the increases of the tetrapods, produce coal areas in both countries.
