[amp_mcq option1=”plate tectonics” option2=”sea floor spreading” option3=”continental drift” option4=”isostasy” correct=”option1″]<\/p>\n

The correct answer is: A. plate tectonics.<\/p>\n

Plate tectonics is the theory that the Earth’s surface is made up of a number of rigid plates that move relative to each other. These plates are constantly colliding, grinding, and sliding past each other, which is what causes earthquakes, volcanoes, and other geological activity.<\/p>\n

The deep oceanic trenches are formed when one tectonic plate is subducted under another. This happens when the denser plate sinks beneath the less dense plate and is forced down into the Earth’s mantle. As the plate descends, it melts and the magma rises to the surface, forming volcanoes.<\/p>\n

The other options are incorrect because they do not explain the formation of deep oceanic trenches.<\/p>\n
