The Lithosphere is made of the two types of crust, denser oceanic crust and thicker conteniental crust, plus the upper rigid part of the mantle.
The Lithosphere float on the semi-liquid Asthenosphere. The Asthenosphere moves through a process known as convection. The convection form currents moving hotter less dense mantle toward the surface where it cools becomes denser and sinks.
Another name for the asthenosphere is the ?
According to the infographic above, one of the largest earthquakes of this year 2021 was the magnitude 8.2 Earthquake in Alaska on 29 July 2021. Earthquakes represent a release of energy as a result of the earth's tectonic plates. a) Determine the amount of energy release in ergs. b) Determine the energy release in Joules. ( Hint use the earthquake formula M = 2/3 log (E/ 10^11.8); where M is the earthquake magnitude and E is the energy of the earthquake in ergs (recall 1 erg = 10^-7 Joules)). c) Using the earthquake magnitude scale below to qualitatively categorize (was it Minor, Light, Moderate, Strong, Major or Great) and describe the earthquake (what kind of damage is expected from a magnitude 7.1 earthquake)
