Glaciers in South America develop exclusively on the Andes and are subject to the Andes various climatic regimes namely the Tropical Andes, Dry Andes and the Wet Andes. Apart from this there is a wide range of altitudes on which glaciers develop from 5000 m in the Altiplano mountains and volcanoes to reaching sealevel as tidewater glaciers from ...
During the Last Glacial Maximum, much of the world was cold, dry, and inhospitable, with frequent storms and a dust-laden atmosphere. The dustiness of the atmosphere is a prominent feature in ice cores; dust levels were as much as 20 to 25 times greater than they are in the present.
Three major ice centers formed in North America: the Labrador, Keewatin, and Cordilleran. The Cordilleran covered the region from the Pacific Ocean to the eastern front of the Rocky Mountains and the Labrador and Keewatin fields are referred to as the Laurentide Ice Sheet. Central North America has evidence of the numerous lobes and sublobes.
A chronology of climatic events of importance for the Last Glacial Period, about the last 120,000 years The Last Glacial Period caused a much lower global sea level.. The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the ...
Patagonia (Spanish pronunciation: [pataˈɣonja]) is a geographical region that includes parts of Argentina and Chile at the southern end of South America. The region includes the southern section of the Andes mountain chain with lakes, fjords, temperate rainforests, and glaciers in the west and deserts, tablelands, and steppes to the east.
In 1525, Spanish navigator Francisco de Hoces discovered the Drake Passage while sailing south from the entrance of the Strait of Magellan. [2] Because of this, the Drake Passage is referred to as the "Mar de Hoces (Sea of Hoces)" in Spanish maps and sources, while almost always in the rest of the Spanish-speaking countries it is mostly known as “Pasaje de Drake” (in Argentina, mainly), or ...
The main factors affecting sea level are the amount and volume of available water and the shape and volume of the ocean basins. The primary influences on water volume are the temperature of the seawater, which affects density, and the amounts of water retained in other reservoirs like rivers, aquifers, lakes, glaciers, polar ice caps and sea ice.
The ice mass feeds dozens of glaciers in the area, among which are the Upsala (765 km 2), Viedma (978 km 2) and Perito Moreno (258 km 2) in the Los Glaciares National Park in Argentina, and the Pío XI Glacier or Bruggen Glacier (1,265 km 2, the largest in area and longest in the southern hemisphere outside of Antarctica), O'Higgins (820 km 2 ...
