Why Are Volcanoes Prevalent In Certain Parts Of The Earth?

Why are volcanoes prevalent in certain parts of the earth?

 

Volcanic eruptions occur only in certain places and do not occur randomly. This is because the Earths crust is broken into a series of slabs known as tectonic plates. These plates are rigid, but they "float" on a hotter, softer layer in the Earths interior.

Multiple choice answer help me figure this out!!!!   Answer: A, B, C, D, E, F Step-by-step explanation: Explanation for A and B: Perpendicular lines meet each other and forms 90 degrees angles. Explanation for Letter C: FG acts as a bisector to DE because it cuts the line segment into two parts. Explanation for letters D and E: DH and EH are congruent because of the midpoint. Explanation for Letter F: As you look at the diagram, we will see that line segments DE and FG has the commo n end point at the middle that divides into two equal parts.

a flower falls from a windowsill 9.2 meters above the sidewalk. How fast is the flower pot moving when it strikes the ground? How much time will it take for the flowerpot to hit the ground?   Good Day Problem: a flower falls from a windowsill 9.2 meters above the sidewalk. 1. How fast is the flower pot moving when it strikes the ground? Given Data: a (acceleration) = 9.8 m/s² d (distance) = 9.2 m Vf (final velocity) = ? unknown Vi (initial velocity) = 0 m/s Solution: We can use the formula Vf = √2ad Vf = √2ad     = √2 × 9.8 m/s²  × 9.2 m    = √180.32 m²/s²     = 13.43 m/s Answer: 13.43 m/s 2. How much time will it take for the flowerpot to hit the ground? Given Data: a (acceleration) = 9.8 m/s² Vf (final velocity) = 13.43 m/s Vi (initial velocity) = 0 m/s t (time) = ? unknown Solution: we use the formula t = Vf-Vi/a t = Vf-Vi/a  = (13.43 m/s - 0 m/s)/ 9.8 m/s²   = 13.43 m/s  / 9.8 m/s²   =  1.37 seconds Answer: 1.37 seconds
