Terraforming Mars: from CFCs to Total Recall
... are points of neutral gravitational stability. L1 is located between the planet and the Sun.) Mars also lacks plate tectonics and volcanism. On Earth, these processes recycle CO2 back into the atmosphere after it is lost through silicate...

Asteroid impacts on the increase since the age of the dinosaurs
... what might have occurred on Earth, as it is likely that when one is hit, so was the other. And without plate tectonics and human activity to destroy the evidence of the impact, the Moon’s surface would be an almost perfect preservation...

InSight detects first marsquake
... to detect. Mars is a lot quieter than Earth - by far. Our dynamic world with its crashing waves and plate tectonics makes for a very loud planet when it comes to determining what is going on inside. Scientists have already though...

2.2 billion year old impact crater is confirmed as Earth's oldest
... now. Finding evidence of these ancient collisions is difficult. Earth is very active and it’s land is constantly resurfaced through plate tectonics and volcanoes, amongst other things. Craters older that Yarrabubba most likely exist and indeed rocks...
