Answer:
Trenches are formed by subsection, a geophysical process in which two or more of Earth's tectonic plates converge and the older, denser plate is pushed beneath the lighter plate and deep into the mantle, causing the seafloor and outermost crust (the lithosphere) to bend and form a steep, V-shaped depression.

Answer: The second image best represents the relationship of the concentration of hydrogen ions between water, vinegar and ammonia.
Explanation: pH is the measure of alkalinity and acidity of a substance in a logarithmic scale.
Mathematically,
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
The solutions which lie in the pH range of 0 - 6.9 are considered as acidic solutions and they have more hydrogen ion concentration.
The solution which has a pH value of 7 is considered as a neutral solution and this solution has same hydrogen and hydroxide ion concentration.
The solutions which lie in the pH range of 7.1 - 14 are considered as basic solutions and they have less hydrogen ion concentration.
- For vinegar, the hydrogen ion concentration is very high.
- For water, the hydrogen ion concentration will be equal to the hydroxide ion concentration.
- For ammonia, the hydrogen ion concentration is very less.
