Question.
Give reasons, we cannot go to the center of the earth.
( Chapter - 2 Inside Our Earth, Class 7 NCERT, Our Environment( Geography) )
Answer.
If we want to go to the center of the earth, we have to drill deep around 6371 km from the earth's surface as the radius of the earth is around 6371 km.
Drilling such deep on the earth is not possible because temperature and pressure increase with the increase of depth on the earth. As per estimates, there is an increase of one degree in temperature per 32 to 40 meters of depth. There is a very very high temperature in the inner core of the earth. As of now, we do not have the technology and tools to drill in such a depth where there is a very high temperature and pressure. Our existing drilling machinery tool will melt.
Even if we try to drill in such a depth, it would be disastrous and the consequences of disaster even we can not imagine.
That is why we cannot go to the center of the earth.
