Explanation:
There are two sources of dissolve oxygen into water: the atmosphere as well as from the water plants. Phytoplankton or any submerged plants are the main source of oxygen in a pond. These phytoplankton produce oxygen by process called as photosynthesis in the presence of solar energy and emit this oxygen into the pond
Answer:
A trench forms in an underwater subduction zone, often near continental boundaries.
Explanation:
Trenches are often found close to continents because of the subduction boundaries in which a plate made of oceanic crust slides underneath a less dense plate made of continental crust. The downward movement of the denser oceanic plate causes the formation of a deep underwater chasm. It is important to note that near divergent oceanic plate boundaries, the separating plates form an underwater ridge, not a trench.

Answer: convergent plate boundries
Explanation:
At convergent plate boundaries, where two continental plates collide earthquakes are deep and also very powerful. In general, the deepest and the most powerful earthquakes occur at plate collision (or subduction) zones at convergent plate boundaries.
