Answer:
The following graph gives information about how a ship lock works. It shows how the process is done. The items include a ship lock, a ship, dams, and pipes under the bottom. You can see from this graph that the first step is that the upstream gate opens and the ship goes into the lock. You can see from this graph that the second step is that the upstream gate closes and the water level evens. You can see from this graph that the third step is that the downstream gate opens and the ship moves out of the
lock. In conclusion, this graph is very informative.
