An important property of Earth (and other planets) is that the temperature increases with depth, from close to 0$^circ$C at the surface to about 5000$^circ$C at the center of the core. In the crust, the rate of temperature increase is about 30$^circ$C/km. This is known as the geothermal gradient.

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

An important property of Earth (and other planets) is that the temperature increases with depth, from close to 0

A	TRUE
B	FALSE
C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -The geothermal gradient is the amount at which the Earth’s temperature increases with depth. It indicates heat owing from the Earth’s warm interior to its surface. On average, the temperature increases by about 25°C for every kilometer of depth.

Detailed explanation-2: -Earth Gets Hotter the Deeper You Go Earth’s geothermal gradient is 15° to 30°C/km within the crust. It then drops off dramatically through the mantle, increases more quickly at the base of the mantle, and then increases slowly through the core.

Detailed explanation-3: -The average rate of temperature rise with the depth from the surface of the interior of the earth is 1°C per 32 meter. Geothermal gradient is the rate of increasing temperature with respect to increasing depth in the Earth’s interior.

Detailed explanation-4: -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-5: -The temperatures increase as you go deeper into the earth, with the Lithosphere, compromised of the Crust and upper mantle, being the coolest averaging about 300-500°C. The Asthenosphere is the next layer, averaging about 1, 300°C, making it slightly more fluid than the lithosphere above it.
