Answer:
Subducting convergent boundary
Explanation:
Generally, volcanoes occurs in both divergent and convergent boundaries. But the convergent boundary it occurs is usually associated with subduction.
Divergent boundary, plates move away from each other creating a new crust in the process. The diverging plates creates the space for magma to be squeezed through cracks and fissures. The magma's erupt to form volcanoes. In the Atlantic ocean the spreading of the plates causes an upwelling of magma through the crest of the Atlantic ridges. New oceanic crust are formed through this process. Sometimes the magma eruption forms volcanoes that are higher than the sea level.
Convergent boundary , plates collides with each other . But in the case of volcanoes existence , the collision should be between a denser plate(oceanic plates) and a less dense plates(continental plates) so that subduction can take place. The subducted plates (oceanic plates) creates trenches and get expose to high temperature and pressure as it sinks toward the mantle. The upper mantle rocks melts and migrate to the earth surface forming volcanoes . Over 75% of the volcanoes occur along the pacific basin where convergent boundary is dominant. Pacific ring of fire has one of the most number of volcanoes.
It's B because it talks about if it harms people. That would be an example of a medical/ethical issue.
Answer:
C. The information is always easily restored."
Explanation:
When the personal information stored digitally on a computer is accidentally
deleted, the data is even stored in the hard disk in various fragments until it is not permanently deleted. Hence the correct option will be "C. The information is always easily restored."
We don't know. The only way we have to explain it is as the result of
a "Doppler effect", that is, by assuming that the star is approaching us.
But if the Doppler effect is really at work in the cosmos, then the vast
majority of galaxies, along with all of their stars, are receding from us ...
as if space itself and the entire universe were expanding !
That's the current assumption, because no other plausible cause
has been found for the shift of spectra from distant objects. But
nothing in science is ever settled, and the search goes on.
