Sentences with phrase «snow crystals into»

The metamorphism of snow crystals into firn and eventually ice occurs as the weight of overlying material causes crystals to settle deform, and recrystallize, leading to an overall increase in unit density.

Libbrecht has urged Garcke to incorporate the proposed instability, which transforms thick prismlike snow crystals into thin plates, in the team's simulations.

Not exact matches

Each snow crystal forms when water vapor in the clouds condenses into ice.

Snow crystals can grow into a wide variety of shapes, ranging from thin, plate - like flakes to slender hexagonal columns, and what shape they take depends on the temperature in which they grow.

The molecular structure of snow crystals also emits energy back into the sky on clear nights — which serves to cool the snowpack.

When firn is buried beneath subsequent snow accumulations, density increases as air spaces between the crystals are reduced by mechanical packing and plastic deformation until... interconnected air passages between grains are sealed off into individual air bubbles (Herron and Langway, 1980).

Glaciers are created when decades upon decades of snow compact themselves into hard ice and as the ice crystals grow, they push out the air, creating a denser and thicker ice.

Once an ice crystal has formed, it absorbs and freezes additional water vapor from the surrounding air, growing into a snow crystal or snow pellet, which then falls to Earth.

When firn is buried beneath subsequent snow accumulations, density increases as air spaces between the crystals are reduced by mechanical packing and plastic deformation until... interconnected air passages between grains are sealed off into individual air bubbles (Herron and Langway, 1980).
