Answer:
Beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth.
Explanation:
The thermocline is one of the three ocean zones when it comes to separating the ocean waters by temperature and weather waters mix or not. The top layer of water, or the surface water, is called the epilimnion. The second layer, or thermocline, is called metalimnion at starts from 200 meters of depth. And the last one, or deep ocean, is the hypolimnion, starting from 1,000 meters of depth.
The surface layer is the one where the water is the warmest and it mixes. In the second layer, we have the thermocline, where the water is not mixing anymore and it sharply drops in temperature. The water temperature generally drops by 1 degree Celsius per 100 meters of depth. The third layer is the coldest, but there aren't big changes in temperatures between the starting and endpoint of it.

The biggest obstacle to traveling by boat on the Congo River is A. the many cataracts
The numerous cascades on the Congo River are the main challenge for boat passage. Navigation on the Congo River is challenging and dangerous due to a number of strong cataracts, or rapids and waterfalls. The hills and troughs in the riverbed that force the water to flow quickly across them are what generate these waterfalls.
On the Congo River, there are a total of seven major cataracts that make navigation extremely difficult and demand that boats be unloaded and portaged around. There are also shallow places brought on by the drought. Because of the ideal growing conditions provided by these shallow locations, the water plants flourished, producing troublesome obstructions for the boat.
