Answer 1

1. The lowest NATURAL temperature ever recorded on Earth was -89.2 °C, (-128.56 F), recorded in 1983 at the Russian Vostok Station in Antarctica.

2. There are many, MANY different kinds... Here are just 5 from the Magono and Lee Classification of Snow Crystals...

P2b: Stellar crystal with sectorlike ends.
P2c: Dendritic crystal with plates at end
P2g: Plate with dendritic extensions
P1c: Crystal with broad branches
R1d: Rimed stellar crystal

(Unless you are looking for names of different kinds... then Diamond Dust, Precipitation Particles, blowing snow, Air Hoarfrost or Surface Hoarfrost


3. By definition... Edible: any substance that can be metabolized by an organism to give energy and build tissue.

Snow can do neither of these things. It can be melted and then you can drink it, but "edible"?... No.

4. There are two formulas for calculating the wind chill effect; one called the old formula and one called the (obviously) new formula. The new formula has a more intense and chilling result.
So depending on what formula you use...

Old = -35 F
New = -37 F

5. Skating by origin belong to the North, to the Scandinavians and Germans for there is no record that the Romans or Greeks knew anything about it, nor is there any word or term in their languages to express skates or skating. The skate in its most primitive form was most probably made of wood and was used
on both snow and ice.

The Origin of Skates in anything like their present form cannot be placed farther back than the so-called Iron Age or about A.D. 200, that is to say, when iron first came into general use in the Northern countries. But the art of sliding on snow shoes or on runners on ice from which skating is derived, is much older than this, and for obvious reasons was practiced only by the inhabitants of the Northern lands. Probably the first of these were the Finns by reason of which from remote times they were called "Skrid Finnai" or "Sliding Finns" which were also a common name for the most ancient inhabitants of Sweden.

6. natural force?? 1. Friction 2. Wind 3. weight 4. temp (this will determine what shape the snow crystals are, jagged or more rounded, believe it or not, effecting the speed of the luge sled.)

7. Skeleton is a type of small, very low, steel-frame sled on which one person, lying face down, slides headfirst down snowy hillsides or down steeply banked, curving, iced chutes similar to those used in luge and bobsledding.

8. Top speeds attained in skeleton—approximately 80 mph (130 km/h) The world record was just broken on 7-12-2006 by Katie Uhlaender (USA) at the FIBT Skeleton World Cup Tour (she reached a top speed of 82.45 mph.) WOW!

9. The winter solstice is the shortest day of the year, respectively, in the sense that the length of time elapsed between sunrise and sunset on this day is a minimum for the year.

10. Four major continental glaciations are recorded in North America. The last (Wisconsin) began about 70,000 years ago, and ended 10,000 years ago. At the peak of the last glaciation, approximately 97% of Canada was covered by ice. Animals and plants that once lived in glaciated regions survived in refuges in Alaska and the Yukon, possibly on Banks Island, and in the northern United States. Probably the thickest ice (approximately 3,300 m) occurred over Hudson Bay.

11. Since glaciers move, they can pick up and transport rocks and thus erode. Since they transport material and can melt, they can also deposit material. Glaciated landscapes are the result of both glacial erosion and glacial deposition.

Different types are as follows:

a) Glacial striations - long parallel scratches and grooves that are produced at the bottom of temperate glaciers by rocks embedded in the ice scraping against the rock underlying the glacier.
b) Glacial polish - rock that has a smooth surface produced as a result of fined grained material embedded in the glacier acting like sandpaper on the underlying surface.
c) Cirques - bowl shaped depressions that occur at the heads of mountain glaciers that result form a combination of frost wedging, glacial plucking, and abrasion. Sometimes small lakes, called "tarns" occur in the bottom of cirque.
d) Glacial Valleys - Valleys that once contained glacial ice become eroded into a "U" shape in cross section. Stream erosion, on the other hand, produces valleys that are "V" shaped in cross section.
e) Arêtes - If two adjacent valleys are filled with glacial ice, the ridges between the valleys can be carved into a sharp knife-edge ridge, called an arête.
f) Horns - Where three or more cirques are carved out of a mountain, they can produce a sharp peak called a horn.
g) Hanging Valleys - When a glacier occupying a smaller tributary valley meets the larger valley, the tributary glacier usually does not have the ability to erode its base to the floor of the main valley. Thus, when the glacial ice melts the floor of the tributary valley hangs above the floor of the main valley and is called a hanging valley. Waterfalls generally occur where the hanging valley meets the main valley.
h) Fjords - Fjords are narrow inlets along the seacoast that were once occupied by a valley glacier, called a fjord glacier.

12. A Musher

13. I'll give you 3 out of the 7 BIG steps (just to be safe) LOL. a) Jump upslope. b) Move to the side of the avalanche. c) hold on to something (like a tree).

14. (your question got cut off, so I'll assume the question is "What do you do if are becoming hypothermic?")

Get inside to room temperature and cover with warm blankets. (If going indoors is not possible, get out of the wind and use a blanket to provide insulation from the cold ground. Cover and protect your head and neck to help retain body heat.

Once inside, remove any wet or constricting clothes and replace them with dry clothing.

Apply warm compresses to the neck, chest wall, and groin. Also drink warm, sweetened, NONalcoholic fluids to aid the warming.

Get medical help!

DO NOT use direct heat (such as hot water, a heating pad, or a heat lamp) to warm yourself!!!
DO NOT drink ANY alcohol!!!


So how did I do? LOL

Answer 2

1) acording to most of the sources i checked, -129 F is the coldest natural temperature recorded
3) dictionary.com defines edible as "suitable for use as food," and as water is used in all foods, one could argue yes, snow is edible, but i wouldn't eat just any old snow laying around.
6) Oh come on, friction between the luge and the snow.
7) pretty much like the luge, except on their backs, not their stomachs
9) when the part of the earth you're on is tilted away from the sun. the temperature drops.
11) their great weight and jagged bottoms carve out (or flatten) the ground they pas over
12) wikipedia claims they are called "mushers"
14) what?

Answer 3

1)...Lowest temperature ever recorded on earth (-129 °F) was at Vostok on July 21, 1983.
2)...The main five crystal categories are diamond dust, precipitation particles, blowing snow, air hoarfrost, and surface hoarfrost
3)...Yes, but be careful of the yellow bits!!!
4)...1500Kg cal/Mh/h
5)...1742
6)...Friction
7)... Silly silly people who, in my opinion, are stoned out of their minds and, sit on a tea tray and ninetystupid mph down the bobsleigh course
8)... All depends upon the start push, length/gradient of course, temperature, weight of "pilot" etc etc ... But stoopid mph!
9)...The winter solstice is the shortest day of the year
10)... 10th December 7993BC.
11)... They make it cold.
12)... Mushers.
13)... Big ones!
14)... Stumbles, mumbles, fumbles and grumbles.

Answer 4

This is your homework isn't !!! found out yourself you lazy ****
