Which statements are true descriptions of Earth's interior layers? Select the two correct answers.(1 point)
Responses
The mesosphere is the outermost layer of Earth.
The mantle is composed of silicate material.
The asthenosphere is located below the lithosphere.
The crust is composed of iron with nickel and sulfur.
The outer core is composed of different elements than the inner core.
The mantle is composed of silicate material.
The asthenosphere is located below the lithosphere.
The correct statements are:
1) The mantle is composed of silicate material.
2) The asthenosphere is located below the lithosphere.
To determine which statements are true descriptions of Earth's interior layers, we need to analyze the characteristics of each layer.
1. The mesosphere is the outermost layer of Earth.
This statement is incorrect. The mesosphere is not one of the recognized layers of Earth's interior. The outermost layer is the crust.
2. The mantle is composed of silicate material.
This statement is correct. The mantle is predominantly composed of silicate rocks, which differentiate it from the crust and the core.
3. The asthenosphere is located below the lithosphere.
This statement is correct. The asthenosphere is a semi-fluid layer located below the rigid lithosphere.
4. The crust is composed of iron with nickel and sulfur.
This statement is incorrect. The crust is mainly composed of less dense rocks like granite and basalt, and it contains little iron, nickel, or sulfur. On the other hand, the core is rich in iron and nickel.
5. The outer core is composed of different elements than the inner core.
This statement is incorrect. Both the outer core and the inner core are primarily composed of iron and nickel, with some trace elements.
Based on our analysis, the two correct statements about Earth's interior layers are:
- The mantle is composed of silicate material.
- The asthenosphere is located below the lithosphere.
