Answer:
A. True
Explanation:
Oceanic crust, while older than plateaus of rocks found far away from volcanic activity, it is much thinner, denser, younger, and of different chemical composition than continental crust. Continental crust is typically 30-50 km thick, whilst oceanic crust is only 5-10 km thick. On the other hand, plateaus of rocks are formed from volcanic activities and are of more recent occurrence than oceanic crust.
Answer:
Air rushes in and fills the lungs that is where the air goes as a result.
Explanation:
The correct answer is - days or years before the major earthquake.
The foreshocks always come before the major earthquake. They can appear only a single day before it, weeks, months, or even years. It is a nice indicator that something bigger is coming, so if people are wary enough they can avoid the devastating effects of the major seismic activity afterwards.
For example, we can take the foreshocks and the major earthquake in Ohrid, Republic of Macedonia, in the summer of 2016, where the foreshocks started about two months earlier, and they were present every day for those two months, slightly increasing in intensity, until the major earthquake of 6.9 magnitude according to the Richter scale came.
In this example, the biosphere is very dependent on the hydrosphere.
