Study the graph below. at what depth does the thermocline begin? a line graph relating ocean depth to water temperature. at 0 meters, temperature is approximately 27°c. at 100 meters, temperature is approximately 24°c. at 200 meters, temperature is approximately 11°c. at 300 meters, temperature is approximately 8°c.
The thermocline in an aquatic ecosystem presents a layer of water which has a steep decline in temperature. In this layer, the temperature of the water drops much faster than in the layers above. This happens because this layer is a ''buffer'' zone between the warm water of the surface layers and the cold layers of the deep.
So, in this case, in the zone between 100 and 200 meters, there is a sharp decline from 24 degrees to 11 degrees.
The thermocline begins at 100 meters of depth.
Thermocline is a transition oceanic water layer between deep and surface water in which water temperature decreases rapidly with increasing depth.
From the given graph it cam be seen that at 100 meters the thermoline begins such that the temperature drops from to .
Hence, the thermocline begins at 100 meters of depth.
