Earthquakes generate compressional waves (p-waves) and shear waves (s-waves). Compared to the speed of shear waves in a given earth material, the speed of compressional waves is the fastest.
Because of this the compressional waves are the first waves to arrive on a complete record of ground shaking. They are also called P waves, which derives from this fact - P is an abbreviation for primary, first wave to arrive.<span>They typically travel at speeds between ~1 and ~14 km/sec.</span>
The answer is D. The rainforest is important to life as a whole on the planet.
Answer: Hanging valleys and waterfalls.
Explanation:
The time or period of the maximum glacial advance, Yosemite Valley was filled with a very big truck of glacier. Little tributary glaciers flowed down adjacent valleys and joined into the trunk. When the glaciers returned, the trunk glacier had cut a very deeper valley than the tributary glaciers, becoming hanging valleys where the tributary glaciers merged the trunk. Today in Yosemite National park, we can see evidence of glacier from the hanging valleys and waterfalls.
Answer:
hot-air balloons
Explanation:
More recently, aerial photographs have often been taken from fixed-wing aircraft and today can even be taken from unmanned aerial vehicles (also knowns as drones).
Answer:
correct answer is option C
Explanation:
Option a cannot be correct since when three is technological stability in the industry environmental uncertainty will remain constant.
Option b cannot be correct since when industry the industry is at an equilibrium state than environmental uncertainty will not be affected.
Option c is correct since environmental complexity affect the environmental uncertainty when environmental complexity is high than environmental uncertainty will be high and when environmental complexity is low than environmental uncertainty will be low.
option d cannot be correct since environmental uncertainty is most likely to be high when environmental change is extensive.
