For every 108 feet descent bellow the surface of earth temperature rises for _________
A
1.8
B
1.9
C
1.10
D
1.20
Explanation: 

Detailed explanation-1: -As a general rule, the crust temperature rises with depth due to the heat flow from the much hotter mantle; away from tectonic plate boundaries, temperature rises in about 25–30 °C/km (72–87 °F/mi) of depth near the surface in most of the world.

Detailed explanation-2: -The temperature is around 1000°C at the base of the crust, around 3500°C at the base of the mantle, and around 5, 000°C at Earth’s centre.

Detailed explanation-3: -The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1, 220 kilometers (758 miles). Temperature in the inner core is about 5, 200° Celsius (9, 392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm).

Detailed explanation-4: -Expert-Verified Answer. It changes due to the geothermal gradient. As one goes closer to the active core of the layers, the particular gradient precisely depicts how the Earth becomes heated. It represents the overall rate at which the temperature of the Earth rises with depth.
