Heat

A BRIEF INTRODUCTION




You are watching: What happens to the air as it gets farther from the heat source

Earth"s warmth is released by both conduction and also convection in Yellowstone. Conduction occurs once heat is transferred from somepoint hot to somepoint colder.

If you stick one finish of a metal rod right into a fire, the energy from the warmth will excite or agitate the molecules in the metal. Those excited molecules will collide with nearby cooler ones, and move power to them, making them hotter. Ultimately, if you organize onto the rod lengthy enough, the warmth will be transferred to your hand also. That"s conduction (and also a possible burn, if you do not let go of the rod).

Convection occurs once heat is transferred by the movement of warm liquids or gases, such as air, water, or magma, to a cooler location. We"ve all learned that hot air rises. This occurs bereason air broadens as it heats, becoming much less dense and even more buoyant than the neighboring cooler air. The farther the air gets from its heat resource, the cooler and denser it becomes, until eventually it starts to sink aacquire. Baseboard heating in a residence, hot air balloons, and water boiling in a pot are all examples of convection. The exact same principle is at work beneath Yellowrock. The convection of molten rock in the underlying magma chamber transfers warm throughout the Yellowrock caldera.

Near the ground’s surface, convection of hot water creates the park’s well known hot springs and geysers.

So much for dry explantions; let"s move on to "cooler" stuff!
