Abstract

A number of landscape features of the surface of Mars have revealed similarities of morphology which may imply similarities of development and by and large, the presence of water, ice and permafrost. A systematic comparative study between landscapes of the Earth and those of Mars may be useful for the understanding of the evolution of Mars and the possible presence of global climatic changes on Mars. The comparative study along a landscape traverse from the poles till the equator on Earth can for this purpose successfully be compared with the Mars. It is concluded that Snowball Earth Stages similar to the Mars icy global stage today occurred periodically on Earth as well. Furthermore the evidence of melting water phenomena observed on Mars images point at protracted thawing inferring a Mars Global Warming today in resonance with the Earth.
