Question

Quizplus · Accepted Answer

Fumaroles are steam vents that result from the boiling away of groundwater before it reaches the surface. Mudpots are also associated with geothermal activity, but they involve the bubbling of mud due to gases escaping from below. Geysers are a type of hot spring that periodically ejects water and steam. Lahars are fast-moving mudflows caused by volcanic activity, and eskers are long, winding ridges of sediment deposited by melting glaciers.
