GEOLOGY

Detailed explanation-1: -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-2: -A high pressure system has higher pressure at its center than the areas around it.

Detailed explanation-3: -The gravitational attraction* between the earth and air molecules is greater for those molecules nearer to earth than those further away-they have more weight-dragging them closer together and increasing the pressure (force per unit area) between them.
