What is the relationship between pressure and gravity in a nebula
Levart [38]
<span> la gravedad en la tierra no es constante ni mucho menos porque depende de la distancia al centro de la tierra... y la tierra no es perfectamente esferica </span>

<span>respecto a la pregunta, la presion atmosferica viene siendo proporcional al peso que el aire ejerce sobre nosotros. Mientras mas gravedad hay en un planeta, mayor es la presion atmosferica a cierta altura. </span>

<span>Ahora, en un mismo planeta, la aceleracion de gravedad disminuye con la altura (porque se esta mas lejos del centro) y la presion tambien disminuye con la altura, porque hay menos aire sobre nuestras cabezas. </span>

<span>espero q te sirva.</span>
