Both scientists are working together to develop a model of earth's layers in order to test their theories. they are using a bunsen burner to represent earth's core and vegetable oil within a large glass container to represent the asthenosphere. given their experimental setup thus far, which of the following would be the best representation of the lithosphere
a. water
b. solid block of clay
c. sand
d. cardboard pieces

D.Cardboard pieces

Explanation:

Cardboard pieces would a good representation of the crust.

The crust of just a thin layer in terms of thickness. We can picture the crust as an apple skin or an orange peel. It's thickness is averages about 5-10km for thinner oceanic crusts and about 30-50km for thicker continental crust.

The crust is the thinnest layer of the earth.

Below the crust is the region of the mantle. The mantle is made of the upper mantle, asthenosphere and mesosphere. The asthenosphere is in a weak plastic form and it is very thick. It averages a thickness of about 190km,about 100 times the oceanic crust and 4 times the continental crust. The mantle is the thickest region of the earth.

The core is the innermosr layer of the earth. It is about 2300km thick.

It would be very ideal to relatively represent the crust as pieces of cardboard floating on an oily asthenosphere.

c. electrical charges of ionic bonds.
