How are continental glaciers and valley glaciers alike?
346226
they are both in a state of movement...  and both shape or create the landscape as the move.

Similar:\n  - the plants roots in both of them are shallow\n  - about the same amount of rain per year\n\nDifferent:\n  - tundra has permafrost\n  - tundra is located more north and desserts are in the middle \n     and south

Makes tasty glaciers, MMMMMMMM.

In the mountains or in the north (usually because of mountain springs and glaciers)

Definitely continental to continental convergence. When continental crust meets continental crust neither will be subducted so they press together under extreme pressure over large amounts of time which leads to deformation of the crust (folding & faulting). This is one of several ways that mountains can be produced. AKA orogenesis.

There is few hints like same geology at diferernt geografic points related to the same period; \nSame fauna indicating same region or at leastthey migrated through some kind of bridge;\nObvious fit about the continents. \nWhat cause it is the tectonic movement. Dorsals have separated it and we still in movement there is measure about hom many inches we are far from Europe/AFrica and also to other continents. (Also Heigh of montains are changind)

Glaciers cannot move across entire oceans.  Large continental ice sheets that grow large enough to intersect a coastline sometimes extend into the ocean (see #1 below).  Their base sits on the seafloor, and in some cases can extend hundreds of miles out to sea.  The West Antarctic Ice Sheet is a continental glacier that is 'grounded' below sea level.  It sits on the continental shelf of the Ross Sea.  In the past (several thousands of years ago), it extended all the way to the edge of the continental shelf.\n\nThese glaciers also usually have whats is called an ice shelf.  An ice shelf is an extension of the glacier that floats on the ocean.  Icebergs are a product of bits of the ice shelf breaking off into the ocean.  Ice shelves can extend several hundreds of miles into the ocean (see #2).\n\nValley glaciers in places like Alaska or Greenland also discharge into the ocean.  The ends of these glaciers typically float and extend out into the bay of the valley where the glacier sits.

I'm not sure there's a correlation between polar regions an altitude, but there's a strong connection between altitude and climate. In a nutshell, higher altitudes have the affect of moving further north (colder) climate. In the polar region this same effect applies, but is less pronounced since there are fewer climate spans.\n\nAlso, I suspect being near glaciers, water masses, etc. need to be considered for micro-climates.

Mountains are primarily ROCK. Most rock is non-porous and therefore holds water from rain or snow melt.

.the mountainous area is cooler than the lowland area.\n\nLike the mountains west of LasVegas and LasVegas itself.

Alfred Wegener, German meteorologist, was gathering climate information with a partner when he started noticing glacial deposits that matched on different continents.\n\nThis led to more study of course. Why were similar deposits found in such far removed places?\n\nWhile looking into this, he also noticed that rocks & fossils on different continents were also identical.\n\nThis, along w/ the "continent puzzle" led to his hypothesis of continental drift. Notice, it is referred to as a hypothesis. This is because Wegener could never provide a driving mechanism for continental drift.\n\nWegener tried explaining how continents could move but to no avail. His explanation that the continental crust literally plowed through oceanic crust did not "cut" it. PUN intended. This was not possible w/o leaving torn crustal plates behind & there was no evidence of that.\n\nMost scientists rejected his hypothesis. Some, however, kept searching for the "driving mechanism" behind continental drift.\n\nIn 1968, scientists could finally provide this force behind the movement of the crust. It was named the theory of plate tectonics.\n\nThis theory stated that the earth's crust was broken down into many major & minor lithospheric plates. These plates moved due to uneven heating of the molten magma in the earth's mantle.\n\nConvection currents w/in the mantle are created by cooler magma sinking & hotter magma rising. As the hotter magma rises towards the asthenosphere, it will cool & then sink. This principle works in the same manner as it does in the atmosphere.\n\nPlates were either pulled apart at divergent boundaries or subducted at convergent boundaries unless it is at two continental convergent boundaries. In this case the two crusts are less dense than the magma below & will deform rather than be subducted.\n\nSo yes, Alfred Wegener did suggest the theory of continental drift. But it was not actually taken seriously until the theory of plate tectonics came along.

You are misunderstanding a few different concepts here.  That is a pretty good definition of uniformitarianism...but it's important to understand that mountains are also building as they are eroding. An example of this is the Himalaya; they are sill rising about 3 inches every decade.  Hardly any erosion takes place on the higher peaks - too cold/covered in snow and ice.\n\nAlso, mountains build up in some areas, some areas erode, and many areas (of land) remain little changed (that's where you get your (relatively) young bones.  Many areas of land are also deposition areas that add material on top of old material (that's why you dig up bones and fossils).\n\nCatastrophism is now viewed as a very legitimate factor. Think of asteroid impacts, volcanoes, or the massive flooding caused by the end of the ice ages (do you think that little Colorado River carved the Grand Canyon?).\n\nSo we rectify both by seeing the proper blending of the two - a largely uniform Earth that is infrequently influenced by catastrophes.

Glaciers flow because of gravity.\n\nView this page:\nhttp://www.answers.com/topic/last-glacial-maximum\nFor info and a pic of what the world probably looked like during the last ice age. The grey denotes glaciers. The land (brown) has been adjusted for the drop in sea level and the ocean temperature difference is shown.\n\nThe ocean levels dropped. Much of the continental shelf which is now under water was exposed, dry land. The water that now covers them was locked up in the the glaciers.\n\nAlso look:\nhttp://uk.encarta.msn.com/encnet/RefPages/RefMedia.aspx?refid=461527006&artrefid=761570002&pn=3&sec=-1
