Answer:
Before mountain building occurred, the area was underwater.
Explanation:
Through excavation, fossils that are of marine animals are often found high on mountain ranges. This seems weird from today's perspective, as marine animals can only be found in ocean waters, and there is no way they can travel on land and upon the mountains. Earth has changed a lot throughout history though, so such occurances are actually not that weird.
The mountains in Pennsylvania are such a place, with an abundance of marine fossils. When we look at the geological past of what is now Pennsylvania we can easily see why this is the case. The whole area was actually underwater for millions of years. This was the case before mountain building occurred here when part of the ocean floor raised high above the surface of the water and created land. As the crust was going up, the fossils on it went up as well.

Explanation:
An epidemic disease is one “affecting many persons at the same time, and spreading from person to person in a locality where the disease is not permanently prevalent.” While a Pandemic is an epidemic that has spread over a large area, that is, it’s “prevalent throughout an entire country, continent, or the whole world.” Hope this makes sense!
Answer:
Modified Mediterranean
Explanation:
The climate of Seattle is sometimes classified as a "modified Mediterranean" climate because it is colder and wetter than most Mediterranean climates. It has cold, wet winters and warm, mostly dry summers.
Seattle gets around 7 days of thunder, while 0.5 inches of snowfall occur each year, on average.
Answer:
Option (3)
Explanation:
Mid-oceanic ridges are the regions along which two distinct plates move away from one another. This type of plate boundary is known as the divergent plate boundary.
Whereas a rise occurs along a divergent plate boundary and is mostly associated with the region of hot-spots, where the magma is forced to rise up forming a gently steeper underwater highland area.
Both these features occur in a divergent plate boundary and plays an important role in pushing the continents apart. So we can conclude that the rises are mostly associated with the region of hot-spots, and ridges are formed due to the seafloor spreading at divergent plate boundaries.
Hence, the correct answer is option (3).
