Trenches are geological feature is most common at oceanic-continental convergent boundaries.
Explanation:
Usually, the oceanic plate, because it is denser, becomes subducted underneath the continental plate. The enormous stress of the two colliding plates causes the plates to warp abit downwards along the boundary causing a trench to form that stretches the boundary.
As the oceanic plate gets subducted and ‘dives’ into the mantle, it begins to melt into magma. Usually, due to the enormous stress along the boundary, fissures develop on teh continental plate along teh boundary. The magma rises through these fissures and erupts at the surface. Several mountains form long the boundary forming another signature geological feature of convergent boundary which is volcanic arc mountains.

Answer:
The correct answer is 3 countering the affect of declining CO2 on photosynthesis.
Explanation:
Carbon di oxide is an important reactant of photosynthesis.The atmospheric CO2 label regulates the rate of photosynthesis.
When the label of atmospheric CO2 decrease the photosynthesis rate also declines.
So to countering the effect of declining CO2 on phosynthesis plants increase the number of stomata in their leaves.
