From a strategic perspective, the United States and Canada are abundant in natural resources like crude oil and natural gas these continents are rich reserves of biodiverse lives and have are resourceful countries.
Recently its found that the presence of natural gas and reserves of oil are found in offshore areas of arctic and Greenland which has untapped with resources as thee ecosystem is untouched by mankind and has plenty of hidden properties that need to be explored.
Hence, the trump government and the U.S, in general, want to take control of these reserves of oil as the oil is a valuable resource for future planning and growth. Thus the trace regulated stakes in these as valuable assets.
Billions of dollars can be spent on for such projects.
"Island ArcsIsland arcs are long, curved chains of oceanic islands associated with seismic activity and mountain-building processes at certain plate boundaries. They occur where oceanic tectonic plates collide. Along one side of these island arcs, there is usually a long, narrow deep-sea trench.At island arcs, the denser plate is subducted and is forced into the partially molten mantle under the less dense plate. The islands are composed of the extrusive igneous rocks basalt and andesite. The basalt originates most likely from the plastic mantle. The andesite originates most likely from the melting of parts of the descending plate and sediments that had accumulated on its surface.Which list identifies minerals present in andesite from the greatest percentage by volume to the least percentage by volume?
"
As the different situations and events gave rise to the seven different tectonic plates which comprises the over all structure of the planet, as there are a number of geological sites that took there shape because of the movement of the different planetary regions, layers, or the components which makes up the deep down trenches and the islands along with the different volcanic hotspots.
Mostly the subduction region is only due the movement or the sliding of the different tectonic plates which gives rise to a way different catastrophic events like the creation of the seismic way may generate the earth quakes inside the different regions.
Along, with that the different climates across the globe are also due the difference in such geological sites.
The youngest age of the shale is 910 ka. According to the principle of inclusions, the shale formed before the tephra, so the tephra must be younger than 910 ka.
