Head River
All rivers have a starting point where water begins its flow. This source is called a headwater. The headwater can come from rainfall or snowmelt in mountains, but it can also bubble up from groundwater or form at the edge of a lake or large pond.

Answer:
Loess.
Explanation:
The Yellow River is the second longest river in China and the fourth longest single river on earth. There are different numbers for its length, depending on the measurement method: 4845 kilometers is the most common one. Its catchment area covers 752,443 km². The river takes its name from the yellowish color that is created by loess that has been removed and washed into the river via streams and tributaries, which in turn fertilizes the land when it floods over its streams, making fertile land on its way.
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.
