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.
Small foreshocks that precede a major earthquake occur days or years before the major earthquake.
Further Explanation:
Earthquake refer to sudden shaking of the ground violently due to volcanic action or movement within the crust of the earth.
Foreshock: It is an earthquake that occurs before occurrence of a large seismic event or earthquake. It is related to space and time. The observation of the foreshocks that are associated with the earthquake reveals that the foreshocks forms a part of the preparation process to nucleation. When earthquake rupture, the process forms a cascade of events, starting from small events like foreshocks that triggers the large events and continue till main shock is triggered.
Example: The 2002 Sumatra earthquake is considered as the foreshock for the 2004 Indian Ocean earthquake and time difference between two events is more than two years.
Therefore, small foreshocks that precede a major earthquake occur days or years before the major earthquake.

warm, inland
At high noon, you can feel warmair coming from inland. During noon, especially in spring and summer, theradiation caused by the Sun warms the land surface more compared to the seasurface. This is because heat is directly applied on the land surface comparedto the ocean.

Digitizing is the process of converting features on a paper map into digital format.
When computer mapmakers digitize map data, they convert the data into computer language . Correct answer: B In order to do this digitizing tablet (also known as a digitizer) connected to your computer is needed. This digitzier will trace over the features. The x,y coordinates of the features are automatically recorded and stored as spatial data.
