Choose the best answer to each of the following. Explain your reasoning.
What is the name of the rigid outer layer of a planet?
- crust
- mantle
- lithosphere
The outermost rigid layer of planet
Answer to Problem 1QQ
The rigid outermost layer of a planet is the Lithosphere.
Explanation of Solution
Introduction:
Based on physical and mechanical properties and composition, a planet is divided into five layers. Lithosphere, Asthenosphere, Mesosphere, outer and inner core.
The outermost rigid layer of planetis Lithosphere which is made up of rigid part of mantle and crust. By mechanical properties, lithosphere is composed of brittle rock portion of the surface of thickness around
Conclusion:
Lithosphere is the outermost rigid layer of a planet.

- Use a logarithmic model to solve. The Los Angeles area experiences many earthquakes. Suppose Los Angeles experienced an earthquake that measured a magnitude of 6.9 on the Richter scale. Suppose that Los Angeles experienced another earthquake years later, which measured 5.2 on the Richter scale. Compare the intensities of the two earthquakes. (Round your answer to the nearest integer.) The intensity of the earlier earthquake in Los Angeles was about times the intensity of the later earthquake.arrow_forwardThe P-wave arrived at a seismic station at 10:19 AM. Create the remaining information and explain your thought process and show your math work below for the following data. How long has the p-wave been traveling? What is the difference in arrival time between the p-wave and s-waves? When is the earthquake origin time? How far away did the earthquake happen? How do i answer this ?arrow_forwardWe need to create a scale model of the solar system (by shrinking the sun down to the size of a basketball or ~30cm). First, we will need to scale down actual solar system dimensions (planet diameters and average orbital radiuses) by converting our units. There are two blank spaces in the table below. We will effectively fill in the missing data in the next set of questions. Use the example below to help you. Example: What is the scaled diameter of Mercury if the Sun is scaled to the size of a basketball (30 cm)? The actual diameter of Mercury is 4879 km The Sun's diameter is 1392000 km If the Sun is to be reduced to the size of a basketball, then the conversion we need for this equation will be: 30cm1392000km Here is how we run the conversion: 4879km×30cm1392000km=0.105cm or 0.11cm if we were to round our answer. This means that if the sun in our model is the size of a basketball, Mercury is the size of a grain of sand. We can also see by looking at the table, that we would…arrow_forward

Using the plots below, what can you deduce about the relationshipbetween the velocities of each of the layers?b. Imagine you can extend the spread of geophone to some large offset. From your answer above, would you expect to see the refracted wave alonglayers as first arrival?arrow_forwardShow your complete, clear and detailed solution.

As long as an organism is alive, it keeps its carbon isotopes in balance with the atmosphere, but at soon as it dies, it stops taking up new 14C, and so the geologic clock starts. You found a shell buried in sedimentary layers, which has 6% of its original 14C left. Determine the age of the shell. Show your work.arrow_forward
