Find the distance between each pair of points<br> (-5.2, 7) and (3,- 4)
Nadusha1986 [10]

Answer:

13.72units

Explanation:

Given parameters:

   Coordinates of the two points  =  (-5.2, 7) and (3,- 4)

Unknown:

Distance between the two points = ?

Solution:

To find the distance between two points, we use the mathematical expression below;

   D = \sqrt{(x_{2}-x_{1}  )^{2} + (y_{2} - y_{1} )^{2}   }

 From the given coordinates;

        x₁  = -5.2      x₂  = 3

        y₁ = 7             y₂ = -4

Now; input the parameters and solve;

  D  = \sqrt{[3-(-5.2)]^{2} + (-4 -7)^{2}  } = \sqrt{67.24 + 121} = 13.72units

The distance between the two points is 13.72units

The many volcanoes located along the edge of the Pacific Ocean make up the Ring of Fire. How does subduction play a role in the
sertanlavr [38]
<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>
<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>
