Answer:
At the top of a seamount, the temperature is generally cooler and the pressure is lower compared to the bottom of a trench. This is because the its closer to the ocean surface, where sunlight and atmospheric conditions can affect the temperature and pressure.
The bottom of a trench is located at a much greater depth and is subject to extreme pressure and temperatures. The temperature at the bottom of a trench can be very high due to the heat generated by tectonic activity and volcanic processes.
