Forces brewing deep beneath Yellowstone National Park could be making one of the largest volcanoes on Earth even bigger, a new study reveals.
In the past decade, part of the volcano has risen nearly five inches, most likely due to a backup of flowing molten rock miles below the planet's crust.
While the rise may not be noticeable to the casual hiker, the activity may have cracked the crust in the park's famous Norris Geyser Basin (NGB), leading to the formation of new fumaroles—holes that vent smoke and gas—and the reawakening of some of the area's geysers, including Steamboat, the largest geyser in the world.
Here's the link to the rest of the article:

I just thought this was interesting, I wanted to be an "earth scientist" when I was young, so this stuff I really find enjoyable reading, even if it is a little scary, not to me, but to some. your sis, hannah
