A camshaft is a shaft to which a cam is fastened or of which a cam forms an integral part.

History.

An early cam was built into Hellenistic water-driven automata from the 3rd century BC.

The camshaft was later described in Turkey (Diyarbakır) by Al-Jazari in 1206.

He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock.

The cam and camshaft later appeared in European mechanisms from at least the 14th century, or possibly earlier.

Snow pertains to frozen crystalline water throughout its life cycle, starting when it precipitates from clouds and accumulates on surfaces, then metamorphoses in place, and ultimately melts, slides or sublimates away.

Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air.

Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals.

Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime.

As snow accumulates into a snowpack, it may blow into drifts.

Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw.

Where the climate is cold enough for year-to-year accumulation, a glacier may form.

Otherwise, snow typically melts seasonally, causing runoff into streams and rivers and recharging groundwater.

Skiing is a mode of transport, recreational activity and competitive winter sport in which the participant uses skis to glide on snow.

Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski Federation (FIS).

Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location.

Human beings have attempted to predict the weather informally for millennia, and formally since the nineteenth century.

Weather forecasts are made by collecting quantitative data about the current state of the atmosphere at a given place and using scientific understanding of atmospheric processes to project how the atmosphere will change.
