Answer :
Final answer:
The temperature at the bottom of Imuruk Lake in Alaska is typically around 0° Celsius, which is consistent with polar lake conditions. Factors such as depth and seasonality influence water temperatures, keeping them near freezing. Therefore, the most accurate choice among the options is 0° Celsius.
Explanation:
Temperature at Imuruk Lake
The temperature at the bottom of Imuruk Lake, located in the far north of Alaska, is typically around 0° Celsius. This temperature is consistent with the fact that many freshwater lakes in polar regions experience temperatures close to freezing, particularly in deeper sections where sunlight cannot penetrate.
In polar climates, lake temperatures can be influenced by various factors such as the season, depth, and geographic location. For example:
- Top layers of water can warm slightly in summer, but deeper layers remain cold.
- The overall climate of northern Alaska influences water temperatures, as temperatures can stay below freezing for a significant portion of the year.
- Ice cover can also affect temperatures, insulating the water underneath.
Given these factors, it is reasonable to conclude that the bottom of Imuruk Lake would not be warmer than freezing, and thus 0° Celsius matches the expected conditions.
