The industry in the United States has changed a lot for the past 50 years. For example, we have advanced technologies, such as robotics and computerized automatization, have transformed manufacturing in the region. Also, farming the region's factories produce greater quantities of goods with fewer workers that in the past.
Answer:
Earth's sedimentary rock can be explained from the crustal plates on earth.
Explanation:
- Earth's most sedimentary rocks are formed in continental or land crust as the oceanic crust is made up of heavier materials such as basalt and has a density of 2.9g/cm cube.
- The tectonic forces that originate deep within the earth layers and the arrange of rocks found at greater depths which are responsible for the density and thickness of the continental land crust are volcanism and earthquake activity.
- Igneous and metamorphic rocks that form along with the sedimentary rocks in the earth's crust and areas of shallow beds close to the shores of continental shelves are of less density and less thickness and those submerged beneath this layer are those of higher mass and density.
- About 40 % of the earth's surface and 70 % of the continental volume is dominated by the earth's crust of terrestrial in origin. In due course of time, the mountain upliftment and isostasy formations have developed the crustal thickness.
Answer:
The correlation is where the fault lines are and earthquakes have happened, the hazard level would increase.
Explanation:
If you look at California, the earthquake hazard is higher than Florida because of the major fault lines in California. A main fault is the San Andreas fault that has caused major earthquakes, like the one in 1906 in San Francisco.
Answer: B
Explanation: The isostatic equilibrium occurs when enormous tectonic plates composed of crustal and upper mantle material are able to float on top of the astenosphere, which in turn is composed of denser rock material. In order for such a thing to be achieved the lithosphere and the astenosphere have to have balanced densities between each other. In other words, the density of the material on top, has to be in balance with the density of the material below it, thus to not have any uplift or sinking occurring between them.
