Answer: A. Frequent earthquakes may occur volcanic activity may be common.

When the plates of the continents and oceans collides, the thin and dense oceanic plate submerged under the thick and less dense continental plate. This process is called as subduction. As the oceanic plate submerged down the earth crust it is exposed to the hot magma. The melting of the subducted plate occurs and this results in the high intensity volcanic eruption and  frequent earthquakes.

Ray Of Light [21]

Answer:

0.095M

Explanation:

HClO4 + NaOH = NaClO4 + H2O

Concentration of acid CA= 0.170M

Concentration of base CB= ???

Volume of base VB= 28.5ml

Volume of acid VA= 16.0ml

Number of moles of acid nA= 1

Number of moles of base nB= 1

From

CAVA/CBVB= nA/nB

CB= CAVAnB/VBnA

CB= 0.170×16.0×1/28.5×1

CB= 0.095M
