Does crustal thickness have anything to do with how life existed and sustained on Earth?
Earth ScienceAsked by: Jessica Moore Why does the Earth’s crust is significant to living beings? The Earth’s crust, along with the upper mantle, has its necessary role in the dynamic creation and destruction of the crustal surface in which all living organisms thrive on. In which layer of the Earth does life exist? Biosphere The The
