Likewise, during melt, thinner sea ice melts faster. The ash melts in the combustion chamber to form molten glass. The ice melts in an endothermic process while dissolving the acid. Climate change melts ice and increases the mobility of the ice. The snow partly melts and partly sublimates in the dry wind. Snow falls rarely, and when it does, it melts at once. It melts at , boils at and sublimes easily. This melts the powder and causes it to adhere to the surface. It melts at about and congeals at . Komatiites are high temperature partial melts of peridotite. During baking, the fat melts away, leaving a flaky texture. Otherwise, snow typically melts seasonally, causing runoff into streams and rivers and recharging groundwater. The river is prone to catastrophic flooding in the Spring when the Himalayan snow melts. The snow melts quickly and is gone within a week. The powder partially melts in the stream, and deposits upon the substrate.
