Ilia_Sergeevich [38]

The Andes in western South America is an example of a landform that arises from the movement of the tectonic plates.

The Andes mountain range is the mountain range that runs along South America's whole Pacific Ocean coast in the west. It is the world's longest continental mountain range, stretching 8500 km.

It was created by the convergence of the South American and Nazca plates towards the end of the Late Cretaceous, at the end of the Mesozoic era. In the relief configuration, seismic movements and consequent volcanic activity have been more significant than external erosive processes.

There are high mountain ranges in the existing morphology, as well as broad high plateaus, deep longitudinal valleys, and vast mountain ranges. Except for in the Argentine-Chilean Andes, transversal valleys are uncommon.

To learn more about the Andes refer to:

What do the atmospheres of venus and mars teach us about our own atmosphere
WINSTONCH [101]
Earth’s atmosphere is a mixture of nitrogen (79%), oxygen (20%), and a small fraction of carbon dioxide, water vapours and other gases. This makes the existence of life possible on Earth. However, the atmospheres on Venus and Mars mainly consist of carbon dioxide. The amount of carbon dioxide on these planets can range from 95% to 97%. This may be the reason no life exists on these planets.

The atmosphere of Venus is about 96 per cent carbon dioxide, with surface temperatures around 737 K (464 °C, or 867 °F).
Venus itself rotates only once every 243 Earth days.
Mars, in contrast, has a thin atmosphere composed of about 95 per cent carbon dioxide, with the remainder being mostly diatomic nitrogen.
