Well, on my friends Tundra he has a little knob on the dash that can adjust the temperature to either hot or cold or somewhere in-between, if it's cold outside he turns the knob to hot, if it's hot outside he turns it to the cold setting. Hope this helps!  :)

Hi,\n\nThis is a fairly complex topic. The basic idea is that because H2O(18) is heavier than H2O(16), it has a higher heat of vaporization.  So, H2O(16) evaporates faster, and as evaporation occurs, the H2O(18)/H2O(16) ratio will decrease for the atmosphere and increase in the water.\n\nThe warmer the water is, the smaller the difference in evaporation rates. So, the ratio of H2O(18)/H2O(16) in atmospheric water vapor is a good indicator of ocean temperature. This becomes relevant for climate change research because that ratio is 'captured' when atmospheric water vapor falls as Arctic (or Antarctic) snow.  By taking an ice core and examining the H2O(18)/H2O(16) ratio of different samples, we can estimate the global temperature at the time that ice froze. This is one of the so-called paleothermometers used to reconstruct the earth's climate history.

Northern Nevada and Utah have great examples of this type of climate. It tends to be warm and dry but does have four seasons. Hard to explain even though I lived in an area like this. It is usually called high desert

>>>>Which nation has the most diverse climates?\n\nThe trouble is that the question doesn't really make much sense. As you point out yourself, you don't know what 'different climates' even means. Neither does anyone else. Ther are an infinite number of climates. Your house for example dooes not have the same climate as your neighbours house. \n\nBecause climates aren't organised in any menaingful way we can't really give a menaingful answer.\n\nYou could ask which nmation has the greatest variation tempetaure, or reainfall, or is affected by the greatest number of major weather systems or conatins the most major biomes similar quetsions and wecould answer those. But 'climates', that's meaningless.\n\n>>>>>>I know the US has just about every climate - tropical, arctic, desert, four seasons, etc.\n\nWell no, the US doesn't have just about every climate. It doesn't have Siberian tundra climate for example, that is found only in Mongolia. It doesn;t have a Riveiera mediterranean climate for example. That's found only in France. And so on and so forth.\n\nAs you point outm youu don't actually know what you mean 'by' climate so you can't say the US has justabout every type.\n\nIn terms of tropical climates the US only qualifies because it counts Hawaii as part of its landmass despite being separated by thousands of miles. But if we are playing by those rules then France can include New Caledonia and the French Antarctic Territories and Great Britain can claim the Falkland Islands and Bristish Antarctic Territory.\n\nAs a result the US, being entirely confined to northern hemisphere climates and Antarctica, has a very poor representation of climates, much less than Engalnd and much, much less than France.\n\nAs you can see it depends too much on undefined factors to give any sort of meaningful answer.  If we are talking about just range of major climate types and we get to include non-contiguous offshore territories like Hawaii then the answer would be France. If we are only including contiguous onshore territories then Australia, Chile or China would encompass the greatest number of major climate systems.\n\n___________\n>>>>>Tropical means temperatures in the 80's and 90's almost year round.+ Very high humidity and dew points.\n\nDavid is also totally wrong on this spoint. Tropical means lying wihtin the tropics, ie between the tropic of Cancer and the Tropic of Capricorn. The summit of Mt Kilamanjaro is tropical, it is  also permanently snowbound.

The weather is determined by the heating and cooling of different areas of earth. If it is winter in the northern hemisphere, it is summer in the southern hemishere, basically because of amount of exposure each hemisphere gets to the sun. This will cause different weather conditions in different areas. \n\nFor example, in Hawaii, the surf is good on the South Shore, but flat on the North Shore in the summer. In the winter conditions are reversed. Hawaii being in the northern hemisphere but relatively close to the equator gets its southern summer swells from winter storms generated near New Zealand in the Southern hemisphere. During the winter, the northern swells are generated by winter storms in the North Pacific.

Answer is C.\n\nThe seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of approximately 23.5 degrees of arc. Thus, at any given time during the summer or winter, one part of the planet is more directly exposed to the rays of the Sun (see Fig. 1). This exposure alternates as the Earth revolves in its orbit. At any given time, regardless of season, the northern and southern hemispheres experience opposite seasons (see Fig. 2 and Month ranges of seasons (below) and Effect of sun angle on climate).\n\nSeasonal weather fluctuations also depend on factors such as proximity to oceans or other large bodies of water, currents in those oceans, El Niño/ENSO and other oceanic cycles, and prevailing winds.\n\nIn the temperate and polar regions, seasons are marked by changes in the amount of sunlight, which in turn often cause cycles of dormancy in plants and hibernation in animals. These effects vary with latitude, and with proximity to bodies of water. For example, the South Pole is in the middle of the continent of Antarctica, and therefore a considerable distance from the moderating influence of the southern oceans. The North Pole is in the Arctic Ocean, and thus its temperature extremes are buffered by the presence of all that water. The result is that the South Pole is consistently colder during the southern winter than the North Pole during the northern winter.\nThe cycle of seasons in the polar and temperate zones of one hemisphere is opposite to that in the other. When it is summer in the Northern hemisphere, it is winter in the Southern hemisphere, and vice versa, and when it is spring in the Northern hemisphere it is autumn in the Southern hemisphere, and vice versa.\n\nIn the tropics, there is no noticeable change in the amount of sunlight. However, many regions (famously the northern Indian Ocean) are subject to monsoon rain and wind cycles. Curiously, a study of temperature records over the past 300 years (David Thompson, Science, April 1995) shows that the climatic seasons, and thus the seasonal year, are governed by the anomalistic year rather than the tropical year.\n\nIn meteorological terms, the winter solstice and summer solstice (or the date maximum/minimum insolation) do not fall in the middle of winter and summer respectively. The heights of these seasons occur up to a month later due to seasonal lag. Seasons though, are not always defined in meteorological terms; see reckoning\n\nCompared to axial tilt, other factors contribute little to seasonal temperature changes. It's a common misconception that the seasons are the result of the variation in Earth’s distance to the sun due to its elliptical orbit.[1] Orbital eccentricity can influence temperatures, but on Earth, this effect is small and is more than counteracted by other factors; research shows that the Earth as a whole is actually a few degrees warmer when farther from the sun.[2] Mars however experiences wide temperature variations and violent dust storms every year at perihelion.[3]\n\nYou could get more information from the link below...

they stabilize dust, control erosion, entrap air polluting gases, conserving water and harboring wildlife. Climate control is obtained by moderating the effects of sun, wind, and rain. Radiant energy from the sun is absorbed or deflected by leaves on deciduous trees in the summer and is filtered by their branches in winter. We are cooler when we stand in the shade of trees and are not exposed to direct sunlight. In winter, we value the sun's radiant energy; Wind speed and direction can be affected by trees.\n\nThere are many and many more , hope i could cover the gist.

Climate exists because weather is dominated by several quasi-permanent weather systems (including a high-pressure over Bermuda which oscillates and low pressures near the poles).  These weather systems do not move much (except for annual oscillations), so weather patterns will emerge from this quasi-stationary setup, and hence we have climates.

The word tundra derives from the Finnish word for barren or treeless land. The tundra is the simplest biome in terms of species composition and food chains.

Geographic location and altitude of the air mass, also the proximity of large bodies of water. Water tends to have a moderating effect on temperature. Moisture content changes at altitude and lower temperatures as moisture is lost in the form of precipitation.\n\nFor example you have on a mountain peak several zones one of which is the zone of precipitation, the altitude at which precipitation is likely to occur. The second is the zone of accumulation which is the altitude at which accumulation of precipitated materials is likely to occur (snow line).

As is typical, loss of habitat is the greatest concern for AT as well as other special biomes.  For example, the polar bear has a yearly cycle in northern Manitoba and Ontario, in which it goes out onto the ice cover of the Hudson Bay in the fall to hunt, and returns in the winter- Recently, the freeze/thaw cycles have changed, and many of the bears are starving or being trapped on the ice.  Efforts are being made now to provide food and chase them off the early-thawing ice with helicopters, but obviously if the trend continues, it's likely a losing effort.  If the challenge is changing weather patterns, there isn't very much we can do, other than try to minimize the climate changes.  Other challenges include development of the area, especially for oil and coal exploration, which might seriously disrupt migration patterns of the large prey animals.  In general, though, the arctic tundra is not among the most threatened habitats, and so is not focused on as much as, for example, wetlands, rainforests, and coral reefs.

Pressure changes affect the wind.  Temperature change determines whether it will rain or snow.

Arctic Lands  \n \n \n  The Canadian Arctic Lands lie north of the treeline and cover 2.6 million km2, or 26% of the country (including the Arctic Coastal Plains, the Innuitian Region, Arctic Lowlands and part of the Canadian SHIELD). Except on the Canadian Shield, where much bare rock is exposed, the mainland TUNDRA is a closed mat with up to 900 species of vascular plants. The richness of tundra vegetation decreases towards the Pole. The islands south of Parry Channel (the official name for the body of water whose parts are called Viscount Melville Sound, Barrow Strait, Lancaster Sound and M'Clure Strait) are rock and moss surfaces; the Queen Elizabeth Islands are a desert of mainly bare rock and soil with patch vegetation on moist sites. \n ....\nhttp://www.thecanadianencyclopedia.com/PrinterFriendly.cfm?Params=A1ARTA0006275\n\nHudson Bay, 822 324 km2, is an immense inland sea that penetrates deeply into northeastern Canada. It is virtually landlocked but is joined to the Arctic Ocean to the north by Foxe Channel and FURY AND HECLA STRAIT, and to the Atlantic Ocean on the east by HUDSON STRAIT. Baffin Island lies athwart the entrance to the bay, and SOUTHAMPTON, COATS and MANSEL islands are lodged across the northern gap. The west coast is devoid of islands, but lying off the east is a string known as the Sleepers, Ottawa, Nastapoka and BELCHER groups. The maximum length of the bay is 1500 km and its greatest width 830 km.\nhttp://www.thecanadianencyclopedia.com/index.cfm?PgNm=TCE&Params=A1ARTA0003881\n\nhttp://www.aina.ucalgary.ca/scripts/minisa.dll/144/proe/proarc/se+arctic,+v.+39,+no.++4,+Dec.+1986,*?COMMANDSEARCH\nhttp://www.lethsd.ab.ca/mmh/grade5/regions/regionscanada.htm
