When Pangaea split up, what happened to the western edge of the North American continent?
Answer and Explanation:
Sustainability is feasible with enhancements in innovation. Current advances make it conceivable to run feasible businesses, yet these are monetarily unfeasible because of our enormous vitality needs.The proficiency of current innovations in changing over vitality to progressively usable structures for example sun powered, wind,tidal and so forth are likewise low, mostly because of innovative boundaries, making huge scale maintainability unachievable,despite the accessibility of enough crude vitality to suit human needs. Consequently, we have the crude vitality lying around, we should simply change over it to a usable structure. Therefore, levels of progress at littler scales just as the nearness of crude vitality for enormous scale support ability are two reasons why manageability is reachable
As referenced above,the primary hindrance to accomplishing supportability is an absence of innovation to understand this. Another significant obstruction is the tremendous populace. A higher populace requests higher vitality, consequently, considerably more vitality should be delivered. At lower levels, manageability is all the more effectively come to even with our current innovative head ways. With a lower populace, while we may not accomplish manageability completely, we could at present bear to utilize assets in a progressively controlled way, and not deplete our current stores at a disturbing rate while we anticipate advancements in economical innovations.
One more boundary is our monetary framework which rewards snappy and quick generation over maintainable development, in this manner organizations will in general center around amplifying benefits instead of accomplishing supportability.
1. a. Lithosphere
If we divide the Earth into layers by their composition, then there are three of them, the crust, mantle, and core. The crust is the thinnest layer, being on the top, and being solid. The mantle is the second layer, lying between the crust and the core. It is a layer where the temperature and pressure are higher, and the rocks are hot and slow-moving. The core is the bottom layer, in the center of the planet. It is the hottest and has the highest pressure, being the densest of the layers and is composed mostly of iron and in lesser percentage of nickel.
2. b. Crust
The Earth is divided into several layers depending on the layers being solid or liquid. There are five different physical layers, lithosphere, asthenosphere, mesosphere, outer core and inner core. The lithosphere and the inner core are the two layers that are solid, thus the layer on top and the layer in the center. The asthenosphere, mesosphere, and outer core are all liquid, though it is a different degree of liquidity, and it is these three layers where the convection currents occur and cause the magnetic field of the Earth, as well as the tectonic movements.
Answer:
The seismic method of exploration are based on the elastic wave propagation
Explanation:
- The seismic methods depend on the velocity of acoustical energy in earth materials i.e generation of pulse waves. The wave theory of time travel and reflection, deflection and absorption are applied to the principal methods of gravity and electric technique.
- Some convectional geophysical techniques are derived and defined as
1. Near-surface applications: For understanding the geology of rocks at greater depths for engineering and environmental studies.
2. Hydrocarbon exploration: For the discovery of various oils and petroleum reserves.
3. Mineral exploration: geologic mapping and geochemical exportation of the ocean deeps.
4. Crustal studies: like the origin of the earth and slabs of rocks for studying the discontinues in earth at various layers.
