If the lithosphere is resting on the asthenosphere and you put a lot of weight on the lithosphere, say ice in a glacier, how would the
lithosphere respond?

Explanation:

Can you think of a solid that can flow?

You use one twice a day! Toothpaste is a solid that can flow. Is the asthenosphere made of toothpaste? Only if the

toothpaste is ultramafic in composition, and then it would only be able to flow if it were really, really hot. Still the

toothpaste analogy gives you a good image of how the asthenosphere might behave if you squeezed it!

Lithosphere

The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid

solid. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is

about 100 kilometers thick. How are crust and lithosphere different from each other?

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
