If so, that could mean you have a healthy relationship with the internet. Good for you. If you'd like to know more about the latter, my colleague Hasan Chowdhury has an explainer .
Satellite image of kettle lakes in Yamal Peninsula (Northern Siberia), adjacent to the Gulf of Ob (right). The lake colors indicate amounts of sediment or depth. A kettle (also known as a kettle hole, kettlehole, or pothole) is a depression or hole in an outwash plain formed by retreating glaciers or draining floodwaters.
