An ice divide is the boundary on an ice sheet, ice cap or glacier separating opposing flow directions of ice, analogous to a water divide.
 Such ice divides are important for geochronology investigations using ice cores, because such coring is typically made on top of a dome of an ice sheet to avoid interference caused by horizontal ice movement.
 Ice divides are used for looking at what the atmosphere was like in history.
 The ice is very accurate because instead of shifting horizontally like normal ice, it moves vertically downward with time trapping gases into its layers.
 Scientist find these ice divides and take ice cores from them, which are typically long cylinder poles of ice, and evaluate them.
 Once they have these ice cores, they are able to look through it and find elements that the snow and ice carried down with it during that time period such as sulfate, nitrate, and other ions.
 These ice cores are important in determining how our atmosphere has changed for the better or worse, and how we can fix it such as the greenhouse effect which discovered when scientist found how much more greenhouse gasses was in our atmosphere than there was in the past.
Types of snow can be designated by the shape of its flakes, description of how it is falling, and by how it collects on the ground.
 A blizzard and snow storm indicate heavy snowfalls over a large area, snow squalls give heavy snowfalls over narrow bands, while flurries are used for the lightest snowfall.
 Types which fall in the form of a ball, rather than a flake, are known as graupel, with sleet and snow grains as types of graupel.
 Once on the ground, snow can be categorized as powdery when fluffy, granular when it begins the cycle of melting and refreezing, and crud or eventually ice once it packs down into a dense drift after multiple melting and refreezing cycles.
 When powdering, snow drifts with the wind or ground blizzard, sometimes to the depth of several metres.
 After attaching to hillsides, blown snow can evolve into a snow slab, which is an avalanche hazard on steep slopes.
Snice is a portmanteau of "snow" and "ice".
 It refers to a type of frozen water whose physical characteristics make it an intermediate between snow and ice: "snow-ice."
 The use of snice has become normative in modern ice construction, in buildings such as the winter ice hotels constructed annually in certain arctic nations, and the elaborate ice palace constructions, where it forms the bonding between ice blocks, rather as mortar does between the bricks of a traditional brick-built structure.
 It is referred to as snow-ice because it has a snow-like appearance (white, soft, and melts in the mouth), but ice-like physical characteristics.
 The term 'snice' can also be used as a compliment or an acknowledgement of good looks.
A snow fort or snow castle is a usually open-topped temporary structure made of snow walls that is usually used for recreational purposes.
 Snow forts are generally built by children as a playground game or winter pastime and are used as defensive structures in snowball fights.
 They are also built and used for make-believe games such as "house", "store", or "community", a game where multiple forts are built in a group.
 Along with the snowman, it is one of the two structures commonly built by children out of snow.
A winter service vehicle (WSV), or snow removal vehicle, is used to clear thoroughfares of ice and snow.
 Winter service vehicles are usually based on a dump truck chassis, with adaptations allowing them to carry specially designed snow removal equipment.
 Many authorities also use smaller vehicles on sidewalks, footpaths, and cycleways. Road maintenance agencies and contractors in temperate or polar areas often own several winter service vehicles, using them to keep the roads clear of snow and ice and safe for driving during winter.
 Airports use winter service vehicles to keep both aircraft surfaces, and runways and taxiways free of snow and ice, which, besides endangering aircraft takeoff and landing, can interfere with the aerodynamics of the craft.
An ice hotel is a temporary hotel made up of snow and sculpted blocks of ice.
 Ice hotels are dependent on sub-freezing temperatures, are constructed from ice and snow and typically have to be rebuilt every year.
 Ice hotels exist in several countries, and they have varying construction styles, services and amenities, the latter of which may include ice bars, restaurants, chapels, saunas and hot tubs.
Freeze Lounge is an Indian Chain of Ice Bar Designed by Ice Box, UK from sculpted blocks of ice, based in New Delhi, India.
An ice palace or ice castle is a castle-like structure made of blocks of ice.
 These blocks are usually harvested from nearby rivers or lakes when they become frozen in winter.
 The first known ice palace (or, rather, ice house, ледяной дом in Russian) appeared in St. Petersburg, Russia, and was the handiwork of Empress Anna.
 Anna Ivanovna, Empress of Russia, commissioned an ice palace in St. Petersburg, Russia, during the winter of 1739-40.
 Architect Piotr Eropkin and scientist Georg Wolfgang Krafft used huge ice blocks measuring 16 m long by 5 m wide, joined together with frozen water, to build the palace.
 The city recreates the ice palace every winter.
A snowplow (also snow plow, snowplough or snow plough) is a device intended for mounting on a vehicle, used for removing snow and ice from outdoor surfaces, typically those serving transportation purposes.
 Although this term is often used to refer to vehicles mounting such devices, more accurately they are known as winter service vehicles, especially in areas that regularly receive large amounts of snow every year, or in specific environments such as airfields.
 In other cases, pickup trucks and front end loaders are outfitted with attachments to fulfill this purpose.
 Some regions that do not frequently see snow may use graders to remove compacted snow and ice off the streets.
 Snowplows can also be mounted on rail cars or locomotives to clear railway tracks.
A snow blower or snow thrower is a machine for removing snow from an area where it is not wanted, such as a driveway, sidewalk, roadway, railroad track, ice rink, or runway.
 The misnomer "snow blower" is often used, as the snow is moved using an auger or impeller instead of blowing it.
 It can use either electric power (line power or battery), or a gasoline or diesel engine to throw snow to another location or into a truck to be hauled away.
 This is in contrast with the action of snow plows, which push snow to the front or side.
