Question

Which of the following may be associated with the collision of two sections of continental crust

Answer 1

Of the following choices;

• earthquakes, volcanoes, and trenches
• hot-spot volcanoes trenches and earthquakes
• earthquakes and a mountain range

The answer is; earthquakes and a mountain range

When the two continental plates collide, there is enormous stress between the two plates and this is why such boundaries are hot spots for earthquakes. When the two plates collide, the submerged plate (usually the oceanic plate) uplifts the continental plate and causes it to fold into a mountain range called fold mountains (an example is the Alps and Andes Mountain Range).
