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.
Decreases? I think.........
The answer is 3%
Explanation:
3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.
San Andreas fault is a transform fault- it means that the two plates are not getting closer and converging or getting away from each other and diverging but rather moving in different directions - the American part is moving South and the Pacific part is moving North.
