Are we actually touching nothing but electrons in reality or can we actually feel things without the electron barier?

Objects in contact with each other never get past the electron clouds of the atoms on their surfaces.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
