As continential plate has a lower density, when the oceanic plate and continetial plate collide the denses oceanic plate will be subducted under the less dense continential plate.
As mentioned in the question, although continential plate is thicker, the continental crust undergoes heating and cooling cycles that lower it’s density, while the oceanic plate was thinner but denser.
Therefore when they collide, the denser plate will slide under the less dense plate due to the convection current of magma.
While features like the ocean trench and volcanoes will be formed due to subduction and the accumulation of continential crust.
Hope it helps!
The constant buckling and moving of the planet's tectonic plates can account for the presence of marine fossils on mountain tops.
If trees are nature's lungs, then the Amazon, being the biggest and least explored rain forest in the whole World, is the Earth's whole respiratory system. Trees use carbon dioxide and produce oxygen, which means they clean the air. If the Amazon is being ruined and no trees are replaced with new ones, and factories are being built instead, this means that humans contribute to air pollution, leading to disastrous consequences for the whole flora and fauna, climate change and altogether influencing humanity.
