Question

Earth’s core has a temperature of about 6000 Kelvin. Earth’s surface has a temperature near 300 Kelvin. The distance from the core to the crust is approximately 5.15 × 106 meters. The temperature gradient between the core and the crust is K/m. Express the answer as a decimal number rounded to three decimal places.

Answer 1

Answer:

The temperature gradient between the core and the crust is  -0.001 K/m.

Step-by-step explanation:

Earth’s core has a temperature of about 6000 Kelvin and Earth’s surface has a temperature near 300 Kelvin.

So, the change in temperature from the core to the crust $=(300-6000)=-5700$ Kelvin.

The distance from the core to the crust is approximately $5.15 \times 10^6$ meters.

Now the formula is.....

Temperature gradient = (Temperature change / Distance)

So, the temperature gradient between the core and the crust will be:   $\frac{-5700}{5.15\times 10^6} K/m = -0.001106... K/m \approx -0.001 K/m$   (Rounded to three decimal places)
