<span>Copper
is a chemical element with symbol Cu and atomic number 29. It is a
soft, malleable, and ductile metal with very high thermal and electrical
conductivity. A freshly exposed surface of pure copper has a
reddish-orange color. Copper is used as a conductor of heat and
electricity, as a building material, and as a constituent of various
metal alloys, such as sterling silver used in jewelry, cupronickel used
to make marine hardware and coins, and constantan used in strain gauges
and thermocouples for temperature measurement.</span>
Number one is his city is being threatened bye rising sea levels due to global warming.

Explanation:
Answer:
Option (B)
Explanation:
The sequential order of coal in term of its highly heated (most valuable) to least heated (least valuable) is given below-
Anthracite > Bituminous > Lignite > Peat
- Anthracite is a high-rank coal comprised of 90-95% of carbon content and only about 5% of oxygen and water content.
- Bituminous also high-rank coal comprised of 70-90% of carbon content and about 50-60% of oxygen and water content.
- Lignite is a low-rank coal and is comprised of 60-70% of carbon and about 30% of oxygen and 30-60% of water content.
- Peat is also a low-rank coal and is composed of less than 50% of carbon and about 50% of oxygen and nearly 70-80% of water.
According to the classification of coal, the amount of oxygen and water content increases from the higher grade coal to the lower grade, and the carbon content decreases from higher grade to the lower grade coal.
Thus, the correct answer is option (B).
Answer:
B
Explanation:
I think this because with all of that rain and wind most likely rivers, ponds, and the rain water in general would overflow and cause floods and what not.
