Question

Study the diagram showing the range of temperature in the Earth’s layers.

Graph of Temperature of Earth apostrophe s Layers, showing start depth at 410 kilometers and start temperature at 1,000 degrees Celsius. As depth increases to 6,370 kilometers, temperature increases to over 6,000 degrees Celsius.

Which temperature most likely corresponds to the asthenosphere?

1,613°C
2,521°C
3,628°C
6,217°C

Answer 1

The asthenosphere is a layer of the Earth's mantle located just below the lithosphere, typically found at a depth of approximately 100 to 700 kilometers. The temperature in this region generally ranges between 1,300°C and 3,000°C.

Given the options:

1. 1,613°C
2. 2,521°C
3. 3,628°C
4. 6,217°C

The temperatures corresponding to the asthenosphere would likely be 1,613°C and 2,521°C. However, since 2,521°C is higher than 1,613°C and still within the expected temperature range for the asthenosphere, it is likely the best match.

Thus, the temperature that most likely corresponds to the asthenosphere is **2,521°C**.
