Galileo's observational contributionsgalileo galilei was the first scientist to perform experiments in order to test his ideas. he was also the first astronomer to systematically observe the skies with a telescope. galileo made four key observations that challenged the widely accepted philosophical beliefs on which the geocentric model was based, thus providing support for the heliocentric model. from the following list of observations, which are the key observations made by galileo that challenged widespread philosophical beliefs about the solar system? check all that apply.- jupiter has orbiting moons.- venus is only seen in a crescent phase.- uranus has a ring system.- neptune has orbiting moons.- the moon has a smooth, featureless surface.- the sun has sunspots and rotates on its axis.- the moon has mountains, valleys, and craters.- venus goes through a full set of phases.

Need asap ! what is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere?
