How can Earth’s layers be defined? Select the two correct answers.(1 point)

Answer 1

Earth's layers can be defined based on physical and chemical properties. The two correct answers typically include:

1. Composition - This refers to the materials that make up each layer, such as the crust (made of silicate rocks), mantle (made of silicate and other minerals), outer core (liquid iron and nickel), and inner core (solid iron and nickel).

2. Physical state - This considers the state of matter within each layer, including solid (crust, inner core), semi-solid (asthenosphere in the mantle), and liquid (outer core).

Answer 2

Which of Earth's layers has the same chemical composition as the mesosphere?(1 point) Responses inner core inner core outer core outer core lithosphere lithosphere asthenosphere

Answer 3

The layer of Earth that has the same chemical composition as the mesosphere (which refers to the lower part of the mantle) is the asthenosphere.

The asthenosphere is part of the upper mantle and shares similar compositions with the mesosphere. The mesosphere itself is part of the mantle as well, situated below the asthenosphere.

So the correct response would be asthenosphere.
