Sal's grandmother cries after seeing Old Faithful erupt because it reminds her of her deceased husband, Sal's grandfather. The eruption of Old Faithful was a special memory they shared together, and seeing it again stirs up emotions and nostalgia for her.
The geyser called Old Faithful.
When Old Faithful erupts, the eruption can last anywhere from 1.5 to 5 minutes. This would be anywhere from 90 to 300 seconds long.
Old Faithful got its name because it erupts fairly quickly and regularly- once every 35 min-2hrs.
Old Faithful Geyser erupts in between intervals. If its last eruption lasted 3-4 minutes long, you will have to wait 95 minutes for it to erupt again. If its last eruption only lasted 2 minutes, you will have to wait for 65 minutes.
A guy stands under it and pushes a button every time there are a lot of people waiting for it.
Hot spot
The Old Faithful geyser found in Yellowstone Park is an example of a hot spring.
Old Faithful erupts approximately every 90 minutes, shooting water up to 180 feet in the air. This regularity makes it one of the most predictable geysers in the world.
No. Old Faithful is a geyser. However, it and the other geysers and hot springs of Yellowstone are the result of heat generated by a supervolcano.
