Let’s carefully analyze the information provided in the table to address the set of conclusions.
1. The mantle is thinner than the crust:
- Thickness of the crust: 30 km
- Thickness of the upper mantle: 720 km
As we can observe from the given thickness values, the upper mantle’s thickness is 720 km, which is significantly greater than the crust’s thickness of 30 km. Hence, the statement that the mantle is thinner than the crust is incorrect.
2. The core is the thickest of Earth's layers:
- Thickness of the outer core: 2,250 km
- Thickness of the inner core: 1,221 km
- Combined thickness of the core: 2,250 km + 1,221 km = 3,471 km
- Thickness of the crust: 30 km
- Thickness of the upper mantle: 720 km
- Thickness of the lower mantle: 2,171 km
- Combined thickness of the crust and mantle: 30 km + 720 km + 2,171 km = 2,921 km
Comparing the combined thickness of the core (3,471 km) with the combined thickness of the crust and mantle (2,921 km), it is clear that the core is indeed the thickest layer of the Earth. So, this statement is correct.
3. The inner core is thicker than the outer core:
- Thickness of the inner core: 1,221 km
- Thickness of the outer core: 2,250 km
From the table, we see that the thickness of the inner core (1,221 km) is less than the thickness of the outer core (2,250 km), making the statement that the inner core is thicker than the outer core false.
Hence, the conclusions supported by the data are:
- The mantle is thinner than the crust: False
- The core is the thickest of Earth's layers: True
- The inner core is thicker than the outer core: False
Therefore, the final assessment is:
```
(False, True, False)
```
