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.
Answer:
The Coriolis effect influences wind direction around the world in this way: in the Northern Hemisphere it curves winds to the right; in the Southern Hemisphere it curves them left.
The correct answer is - inner core.
The Earth's inner core is the deepest layer of the Earth, and it practically represents the center of the Earth. It is a layer composed predominantly of iron-nickel alloy. In here we have the biggest temperatures and pressures, the temperature on the surface on the inner core is estimated to be like that of the Sun's surface, 5430 C degrees.
Floods, hurricanes, tornadoes
