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.
Answer:
The Milankovitch cycles in association with other natural factors explain how glaciers may advance and retreat over periods of d. ten thousand to one hundred thousand years.
Explanation:
The Milankovitch cycles -
This is the movement related to Earth's orbit around the Sun .
There are three cycles , Axial tilt , Eccentricity and precession .
According to this theory , these cycles together affect the amount of the solar heat that is incident towards the Earth's surface and the climatic pattern .
The Milankovitch cycle helps the advance and retreat of ice over the periods of 10,000 to 1000,000 years , but it does not explain the cause of Ice Age.
Vegetation catches precipitation on its leaves, slowing it down or holding it for a while. This gives the ground more time to absorb the water, so there's less runoff.
