A Quote by Seth Shostak
Planets that don't currently sport plate tectonics, such as Venus and Mars, are scarcely habitable. Tectonics might be a requirement of any world that aspires to a rich diversity of life.

If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so.
If you think the shifting tectonics of world history might make for a juicy crime fiction backdrop, the last decade or so has proved you right.
Unfortunately, we haven't found many very old rocks on Earth because our planet's surface is constantly renewed by plate tectonics, coupled with erosion.
Though the theories of plate tectonics now provide us with a modus operandi, they still seem to me to be a periodic phenomenon. Nothing is world-wide, but everything is episodic. In other words, the history of anyone part of the earth, like the life of a soldier, consists of long periods of boredom and short periods of terror.
Mountains aren't eternal: even the most imposing massifs are smoothed away by weathering in a few hundred million years or less. Plate tectonics makes new ones, and without it, our future would be flat.
The plate tectonics of media have shifted where NBC had to become a new media company from an old media company.
The nature of catastrophe is, after all, reasonably unvarying in the way it ruins, destroys, wounds and devastates. But if something can be learned from the event - not least something as profound as the theory of plate tectonics - then it somehow puts the ruination into a much more positive light.
There are other planets besides the Earth and Mars. I'd like to remind you that studying Venus is vital to understanding life elsewhere.
Plate tectonics is not all havoc and destruction. The slow movement of continents and ocean floors recycles carbon dioxide dissolved in the oceans back into the atmosphere. Without this slow speed carbon cycle, Earth's temperatures would cool dozens of degrees below your comfort zone.
We are surrounded by a lot of failed ecosystems; the moon being one, Mars, Venus. There?s evidence of water on Mars and rivers and it didn?t take. Also, we have planets to guard us like Jupiter and Saturn that take the hits of the comets. It is miraculous that we exist on this planet, that it took.
It will be a long time, if ever, before we get to study Earth-like planets orbiting around other stars, so really, the study of Venus and Mars is the best opportunity that we have, and can imagine having anytime in the future, to understand the evolution of Earth-like planets.
I can remember at the age of about six being fascinated by the planets and learning all about Mars and Venus and things.
Venus and Mars are our next of kin: they are the two most Earth-like planets that we know about. They're the only two other very Earth-like planets in our solar system, meaning they orbit close to the sun; they have rocky surfaces and thin atmospheres.
In days gone by, scientists would speak solemnly about our solar system's 'habitable zone' - a theoretical region extending from Venus to Mars, but perhaps not encompassing either, where a planet would be the right temperature to have liquid water on its surface.
Like fire and rain, (fire and rain) you can dirve me insane But i cant stay mad at you for anything, Were venus and mars, (venus and mars) were like diffrents stars, but your the harmony to every song i sing, And i wouldnt change a thing.
The story seems to be that almost every star has a planetary system... and, also, the definition of 'habitable zone' has expanded. In our system, it used to be that only Mars and Earth were potentially habitable. Now we've got an ocean on Europa... Titan.
