Answer:
There is no drawing here to label but I will go on to explain the the various types of waves with a diagram
Explanation:
P wave or the primary waves are the fastest waves in seismic waves. It is usually the first to arrive at seismic station. P waves are called compressional waves because they have ability to pull and push rocks as they pass through them. It is the first waves you notice during an earthquake.
S waves or the secondary waves is slower than the primary waves and moves through solid rocks and can not pass through liquid. It travels outside the earth core, and that has made seismologist to believe that the outer crust is liquid. It moves rocks up and down, side by side.
Surface Waves only travel through the earth crust. It is slower than P and S waves. It is the surface waves that cause physical destruction we notice during earthquake. The strength and extent of damage of surface waves is determined by the depth of the earthquake.
Answer:
they created oxygen for living species
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.
