Answer: Sand Dunes Stabilization
Explanation:
Sand Dunes Stabilization is the process of engaging in actions that keep Sand Dunes in place to protect their Natural Habitat status.
Two such actions can be useful in this scenario.
1. Putting up Vegetation
- The roots of plants can help anchor soil which will reduce the rate at which it is blown around by wind or carried off by water. This will therefore reduce the rate at which sand dunes lose sand.
2. Putting up Wooden Fences
- Putting up Wooden Fences would also help reduce the rate sand dunes end up on roads for the simple reason that it would stop some of them from being blown by the wind and in so doing keep them where they are supposed to be.
Answer:
F Anthracite (the hardest coal)
Explanation:
Coal is a sedimentary rock that is formed from plant materials. These plant materials must have been trapped and compacted in an environment where they are not able decay. Such an environment is a swamp.
The first grade of coal that forms initially in such an environment is called PEAT. Peat is soft coal that still contains some plant materials. It has a high moisture content and the amount of carbon is still quite low.
With increasing pressure and compaction, PEAT grades into LIGNITE which has more carbon atoms in it. Lignite is more combustible although it is quite soft too. Lignite grades into SUB-BITUMINOUS coal and then BITUMIOUS coal.
The highest grade of coal is ANTHRACITE which is a hard coal. It has very little moisture content and rich carbon percentage in it. Anthracite yields more energy compared to other forms of coal. Anthracite is basically coal that forms at the greastest pressure. Beyond this pressure, a metamorphic transformation occurs and the coals changes to graphite.
Based on increasing pressure:
PEAT< LIGNITE< BITUMINOUS COAL < ANTHRACITE
