Sentences with phrase «different planetary surfaces»

Scientists record the size and number of impact craters — and how eroded they are — to determine the ages and histories of different planetary surfaces.

Variations in texture seen in different portions of the fault surface may explain why Costa Rica has complex, patchy earthquakes that do not seem to slip to shallow depths, unlike some other megathrust faults, said first author Joel Edwards, a Ph.D. candidate in Earth and planetary sciences at UC Santa Cruz.

(The ESA spacecraft arrived at Sol's hottest planet on March 11, 2006, where it is being used to investigate how Venus — although similar to Earth in size, mass, and composition — evolved over the past 4.6 billion years to have atmospheric and planetary surface characteristics that now appear very different from those on Earth.)

The idealized GCMs described above are flexible and general enough that it is relatively straightforward to convert them into GCMs for other planets, for example, with different planetary rotation rates and radii and with different thermodynamic properties of the atmosphere, condensable species, and surface.

The whole concept of direct radiation supposedly heating the surface to observed temperatures is wrong and a totally different paradigm involving entropy maximization and thermodynamics at the molecular level is now known to be what explains planetary surface temperatures being higher than what can be explained with radiation.
