Is the Earth heated up by the tides?
Earth ScienceAsked by: Carlos Rothstein Tidal forces contribute to heating in Earth’s interior. “The tides generate friction, and friction leads to heat,” explained René Heller, a scientist at the Max Planck Institute for Solar System Research and a lecturer at the University of Göttingen in Germany. Do tides produce heat? Tidal heating (also known as tidal

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
