As far as a threat, North Korea has been seen as such for many years (since WWII), when North Korea sided with Russia. America and its Capitalism were not fond of the Communist party, and so we have really been fighting/being concerned about Russian influence.
Historically North and South Korea have been in conflict many years before America and Russia got involved. When we did though it got worse.
Trump has done very little to resolve this, some would say he is making it worse.
AND as for any current events ask Google!
Answer:
The active volcanoes are gradually moving away from the oceanic ridge.
Explanation:
- Many oceanic volcanoes occur as long lines of the active end of volcanoes as here in the mid-oceanic ridges the plate is pushed far away from the ridge surface of the earth as these tend to move out in the direction of the movement of the plates.
- Thus the volcanoes are generally found near the active zones or regions of the tectonic plate and associated with the earthquakes occurring on the fault line or shear lines of the plates.
- Spreading of the ridges as a result of the seafloor spreading takes place and the mantel and plates from below are the driving forces that make the volcanoes and convection current that rises through the mantle pushes or spread the volcanoes to the sides like seen in the ring of fire.
The answer is B.sedimentary
I believe it's B, hope this helped
Answer:
Explanation:
Abyssal plain : very level area of the deep-ocean floor typically lying at the foot of the continental rise G
Guyot: A submerged flat-topped seamount H
Deep-ocean basin: portion of the seafloor between the continental margin and oceanic ridge; comprises 30 percent of Earth's surface C
Continental Volcanic Arc: Mountains are formed in part by igneous activity associated with the subduction of oceanic lithosphere beneath a continent A
Deep-Ocean Trench: Long, relatively narrow crease in the seafloor that forms the deepest parts of the ocean. D
Oceanic Plateau: extensive region of the ocean floor with thick accumulation of pillow basalts and other mafic rock E
Seamounts: An isolated volcanic peak that rises above the deep-ocean floor
Volcanic island arc: A chain of volcanic islands generally located a few hundred kilometers from a tench where active subduction of one oceanic slab beneath another is occuring; some trenches run parallel to an arc shapes row of active volcanoes
