Question

activity 2 of 3
in the map of the world shown below, the darkly shaded area of the
map represents regions of the world with a high potential
for earthquakes. the letters on the map represent different locations.
scientists infer that the major cause of most earthquakes is the movement of

a. glacial ice due to unequal heating of earths surface

b. shorelines due to faulting of rock layers on earths crust

c. lithospheric plates due to convection cells in earths mantle

d. continents due to increased greenhouse gasses entering earths
atmosphere

Explanation:

Earthquakes are mainly caused by the movement of lithospheric plates. Convection currents in the mantle drive these plates. When plates interact (e.g., at boundaries), stress builds up and is released as an earthquake. Glacial ice (A) and greenhouse gases (D) are not major earthquake - causing factors. Shorelines (B) are not the direct cause; faulting is a result of plate movement.

Answer:

C. lithospheric plates due to convection cells in Earth’s mantle
