A continental-oceanic boundary where plates collide is called a?

idk but...

Explanation:

At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.

Convergent Boundary

Explanation:

2 colliding plates are called a convergent boundary. With a continental - oceanic convergent boundary, it will most likely create a subduction zone.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
