but I'm telling you whether is the condition of the outside air or atmosphere at a particular time and place it can change quicklytwo elements of weather are about to change as we hike up this hill I'll take that bet what's 5 minutes how about temperature and air pressure even though it's the temperature of the air who still changed as we hiked up the hill it's going to get cooler because we'll be at a higher altitude or elevation the higher we go the cooler the air is and the lower the air pressure how much cooler Connecticut this hill is a very high so it won't get much colder but if we were hiking something like Mount Everest we be talking about serious freezing temperatures Polaris heavier than warmer air and its 6 as it seeks it gets warmer warm air rises back up again when are sinks and Rises like that it causes winds the higher we have the cooler and heavier the air is and the faster it sinks
