<span>The most volcanically active belt on Earth
is known as the Ring of Fire, a region of subduction zone
volcanism surrounding the Pacific Ocean. Subduction zone volcanism
occurs where two plates are converging on one another. One plate
containing oceanic lithosphere descends beneath the adjacent plate,
thus consuming the oceanic lithosphere into the earth's mantle.
This on-going process is called subduction. As the
descending plate bends downward at the surface, it creates a large
linear depression called an oceanic trench. These
trenches are the deepest topographic features on the earth's surface.

<span>The crustal portion of the subducting
slab contains a significant amount of surface water, as well as
water contained in hydrated minerals within the seafloor basalt.
As the subducting slab descends to greater and greater depths,
it progressively encounters greater temperatures and greater pressures
which cause the slab to release water into the mantle wedge overlying
the descending plate. Water has the effect of lowering the melting
temperature of the mantle, thus causing it to melt. The magma
produced by this mechanism varies from basalt to andesite in composition.
It rises upward to produce a linear belt of volcanoes parallel
to the oceanic trench, as exemplified in the above image of the
Aleutian Island chain. The chain of volcanoes is called an island
arc. If the oceanic lithosphere subducts beneath an adjacent
plate of continental lithosphere, then a similar belt of volcanoes
will be generated on continental crust. </span>
Answer:
Erosion
Explanation:
At first the fence posts were straight up, but over time that became tilted. The reason fro this is erosion. The erosion managed to remove part of the ground in whist he fence posts have been placed, thus their basis has been weakened, and they have tilted. If the process continues they will soon fall on the ground. Deposition has occurred for sure somewhere, but from this information it is not clear where. There has not been deposition on one side and erosion on other as the fence posts would have been standing straight if that happened. The deposition always occurs as a result of the erosion, but the material can be deposited anywhere from few cm away to several thousands of km away., depending on the transferring medium.

Answer:
Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.
Explanation:
(if you need a not googled answer)- Igneous rocks are cooled or sollidified lava/ magma.
