Difference between Lithosphere and Asthenosphere
• The difference between lithosphere and Asthenosphere pertain to their compositions.
• While lithosphere is hard and rigid, Asthenosphere is a layer made up of molten rocks.
• Lithosphere stretches from the top of the earth’s crust down to first 100 kilometers while Asthenosphere lies beneath lithosphere
• Rocks are under severe pressure in Asthenosphere, whereas they face much less pressure in lithosphere.
• The mineral composition of lithosphere is varied as it contains more than 80 minerals whereas Asthenosphere is mainly comprised of silicates of iron and magnesium.
• The depth of the lithosphere is about 100 kilometers, whereas the depth of Asthenosphere is 400-700 kilometers.
