Answer:
c. are renewable
Explanation:
There are many energy sources that the humans have learned to use and exploit. Some resources are non-renewable, while some a re renewable. The non-renewable tend to be cheaper for the time being, and they also tend to produce more energy, but the problem is that the reserves will eventually run out. On the other side, the renewable resources are constantly out there, and they can not be spent, which gives them the advantage on the long run.
The alternative energy sources have been more and more in the focus, especially when it comes to the more developed nations. The main reasons for this are that the fossil fuels will eventually run out, and that they are more environment friendly. This has led to development of technology that is able to harvest energy from the sun, water, and wind, all which are natural resources that are constantly present and can not be spent. Some nations have invested so much in these resources that they have gradually started to replace the fossil fuels, with the end goal being stopping the usage of the fossil fuels totally.

Answer:
Rain washes pollutants off streets and into storm drains, which drain into Puget Sound.
Explanation:
"Puget Sound" is a Pacific Ocean inlet that is located in Washington's northwestern coast. It is said that the name "Puget Sound" was given by George Vancouver in<em> 1792,</em> in honor of a lieutenant, Peter Puget, who was very helpful in guiding him through his expedition.
Puget Sound is home to many marine species, such as salmon, Pacific rods, harbor seals, Pacific herring and the like. However, some of these, like the <em>"Olympia oysters,"</em> have been depleted because of human activities. The recession of many species in this area has been increasing over time. It is said that the inlet was contaminated with radioactive water in 1978, when a submarine accidentally released the radioactive water into Puget Sounds.
Another reason for its buildup of pollution is through the <u>"storm water's run-off." </u>When a storm comes, it hits infrastructure's roofs and other surfaces or pollutants. The debris are carried into the drains by rain and are then drained further into Puget Sound.
The toxic chemicals that are carried primarily comes from the roofing materials or human's everyday products.
