They can last for months and cover the entire planet. The seasons are extreme because its elliptical (oval-shaped) orbital path around the Sun is more elongated than most other planets in thesolar system. On Mars the Sun appears about half the size as it does on Earth. ...

In terms of their size and mass, Earth and Mars are quite different. With a mean radius of 6371 km and a mass of5.97×1024kg, Earth is the fifth largest and fifth most-massive planet in the Solar System, and the largest of the terrestrial planets. Mars, meanwhile, has a radius of a...
Sand mobilized by wind forms decimeter-scale impact ripples and decameter-scale or larger dunes on Earth and Mars. In addition to those two bedform scales, orbital and in situ images revealed a third distinct class of larger meter-scale ripples on Mars. Since their discovery, two main hypothes...

"On Earth, a quake of this size would probably break windows, shake things off shelves, etc, but would not bring the house down," Fernando said. Charalambous said the location of the majority of the marsquakes detected by InSight remains uncertain, with a poor understanding of the mechanisms...
On Earth, linear and circular vent eruptions are both capable of driving buoyant plumes to equivalent maximum rise heights; however, linear vent plumes are more sensitive to vent size. For analogous mass eruption rates, linear vent plumes surpass circular vent plumes in entrainment efficiency ...

Mars is the fourthplanet from the Sun and the second smallest planet in thesolar system.It is about half of the size of Earth and is often1.rfrredto as the “Red Planet" because of its red surfaceThe Red Planet has the largest 2. volcano in the solarsystem-Olympus Mons, which is ...
