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.
Answer:
Latitude are the lines parallel with the equator, both above and below.
Longitude are the lines vertical from pole to pole, measured from the Prime meridian.
They are measuring lines used for locating places on the surface of the Earth. They are angular measurements, measured as degrees of a circle. A circle contains 360°. Each degree can be divided into 60 minutes, and each minute is divided into 60 seconds.
One degree of latitude equals 364,000 feet , one minute equals 6,068 feet, and one-second equals 101 feet.
One-degree of longitude equals 288,200 feet, one minute equals 4,800 feet, and one second equals 80 feet.
Pull-apart rift zones are generally associated with a divergent plate boundary.
<u>Explanation:</u>
In geology, rifts are those linear zones where lithosphere is getting pulled apart. Divergent plate boundary, also named as extensional boundary or constructive boundary is a linear characteristic that exist in between both the tectonic plates that tends to move away from each other.
Major rifts can be found alongside the central axis of mid-ocean ridges, where lithosphere and new oceanic crust is created between two tectonic plates in the path of a divergent boundary.
When the two plates pull apart, general faults or breakdowns are developed on both the sides of the rifts and the central blocks start to slide downwards thereby initiating the earthquakes.
