Step by step
Solved in 2 steps
- 1. Describe the behavior of the "lava" once the lamp is up to temperature. In what way(s) does it mimic Magma? 2. What are the causes of the material rising and then falling? 3. What conditions must be present to make this occur? Think about energy but also think about the nature of the materials involved.Which must be true for metamorphism to occur? A) The parent rock must be in solid form. B) Tons of pressure must be applied. C) The process must take place underground. D) All the aboveAccording to the LA Times news report, a moderate magnitude 3.6 earthquake centered near the Granada Hills neighborhood occured on Jan 22, 2020. Use scientific notation in your final results to a) Refer to the Mercalli scale above to identify the intensity level, shaking and description/damage of the earthquake. b) Draw a cross sectional sketch of the earth identifying the FOCUS and epicenter of the earthquake. c) Determine the amount of energy released in ergs and d) Joules.
