Massive Martian volcanoes reshaped Red Planet billions of years ago into what it is today
A latest research has shown that massive Martian volcanoes offered a makeover to the Red Planet billions of years back, making it look like what it is today.
The study appeared in the journal of Nature on Wednesday and suggested that strong volcanic activity literally shook the planet. The results have come as add on to a list of other factors that could have altered the Red Planet into the cold, dry planet known to us.
A massive volcanic structure called the Tharsis volcanic dome made the Red Planet's surface tilt by 20 to 25 degrees nearly 3 billion to 3.5 billion years back.
Tharsis is the host of the largest volcanoes across our solar system, and due to their mass they succeeded in spewing out lava in such huge quantity that Mars’ outer layers rotated around its core.
The formation of Tharsis dome took place 3.7 billion years back ago. Hundreds of millions of years of volcanic activity from there led to the creation of a plateau on Mars, weighing a billion tons. Its mass is about 1/70th the mass of Earth's moon. The mass was so large that it forced the planet’s mantle and crust to swivel around, which changed the position of the poles of the planet and moved Tharsis dome onto its equator.
All this information holds a lot of information because scientists, who carried out the research at the Universite Paris-Sud in Paris, think that this changes the way they look at the planet in its first billion years, the time when there might have been life on Mars.
Such a tilt could have majorly altered the appearance of the planet. The latest findings may explain many puzzling geological features on Mars.
