GEOLOGY

Detailed explanation-1: -For every 33 feet (10.06 meters) you go down, the pressure increases by one atmosphere .

Detailed explanation-2: -Temperature and pressure progressively increase with increased proximity to Earth’s core. Recent studies indicate the core’s temperature may be close to 11, 000 degrees Fahrenheit; that’s nearly 2, 000 degrees warmer than previously thought and hotter than the surface of the Sun, according to a 2013 Forbes article.

Detailed explanation-3: -It is due to the huge weight of the overlying materials like rocks. It is estimated that in the deeper portions, the pressure is tremendously high which will be nearly 3 to 4 million times more than the pressure of the atmosphere at sea level.
