The section "Influence on human beings" makes nothing but poorly-formed throwaway statements. The section title would make a little more sense as "Significance of plateaux in human geography" or suchlike, but ultimately it seems that the body of text here is so insubstantial that the entire section cries out for deletion.

45%? The article claims that 45% of the earths surface is plateaus. Does anyone else think this is extraordinarily high? I dont have any facts to the contrary so I will not alter or delete anything but someone who has some knowledge in the area should take a look. —Preceding unsigned comment added by 71.33.180.222 (talkcontribs) 19:16, 20 April 2007

I agree with you. If 71% of the earth is covered with oceans and if 45% actually is covered with plateaus, then there would be plateaus in the ocean and all land would be a plateau. —Preceding unsigned comment added by Gremanrooster88 (talkcontribs) 00:10, 16 January 2009 (UTC)

I agree with you 208.108.138.227 and Gremanrooster88. I am a geographer and the information about plateaus is totally incorrect. The actually percent gathers to around 10-20% 45% is way to drastic for the concept. Gremanrooster88, you are correct about how you said that if the world was 45% plateaus then there would be plateaus in the ocean and our land-plates would be mostly plateaus as well. Does anybody else have a word in this? I do not want to edit or change the article but if somebody else would that would be great. Remember to change 45% to 10-20% —Preceding unsigned comment added by 71.113.79.227 (talkcontribs) 04:04, 13 April 2009

Plateaus vs Mesas[edit]

As I understand, a Plateau has lower land on one side and higher land (usually mountains) on the other. If it's completely surrounded by low land, it's a mesa, and if completely surrounded by higher land, it's a valley. Should the article be revised to reflect this, or am I completely wrong?

This isn't about Plateaus and mesas, but about the plateau % discussed above, 45% of the landmass of the earth is plateaus, not the whole planet.

It is plateaux not plateau[edit]

A lot of sources and many books spell it plateaux, and they are all American books too so I don't think it is American spelling difference. The article's name and everything spelled plateau should be changed/

I agree. It is plateaux, not plateaus.

The concepts of plateaux[edit]

This article is simple wrong in many concepts:

1. First thing will be to distinguish between the concept of plateaux (simply a flat area), and orogenic plateaux (which have other very important characteristics).

2. Orogenic plateaux are mainly defined are flat (and broad extensive) high-topography (in the Km scale) areas bounded by steep flanks in their margins. This is essential for their definition. Otherwise, they are just plateaux (s.l.), Mesetas (or even cratons).

3. Two other elements needed to define a plateau are:

3.a. The anomalous matle lithosphere and crust thicknesses (and the consequent high heat values). This is, relatively thin mantle lithospere (few 10's of kms the most) and relatively thick crust (> 30Km at least). Do not forget that they are part of orogens!

3.b. The high climatic contrast between arid dry interior (and endorheism) and the humid rainy flanks (exorheism).

Furthermore, there are much more models explaining plateaux formation, such as, tectonic doubling, crustal thickening by shortening, magmatic underplating, lithosphere detachment or delamination, not to mention the climatic-driven expanations...

In essence, the article is realy poorly constrain and with impressive lack of accuracy

Are you sure most of Bolivia is on the Andean plateau?[edit]

Looking on Google Earth I'd say less than a quarter of it is. —Preceding unsigned comment added by 81.147.80.179 (talk) 11:36, 22 September 2010 (UTC)

The Andean plateau is in the middle of the Andes...[edit]

... not "just to the east" of them. I have changed this. —Preceding unsigned comment added by 81.147.80.179 (talk) 11:40, 22 September 2010 (UTC)
