Ventifact Knobs
Ventifact knobs are rocks that have been shaped by wind over time. Imagine being outside on a really windy day and feeling the wind hitting your face. Now imagine that wind hitting a big rock. Over a long time, that wind can wear away little bits of the rock, making it smoother and changing its shape.
Ventifact knobs form in areas with a lot of wind, like deserts or on mountaintops where it's really windy. The wind carries tiny bits of sand or dust and they rub against the rock, slowly wearing it away. Over time, the rock becomes rounder and more like a knob.
These knobs can be really interesting to look at because they come in all different shapes and sizes. Some look like mushrooms or lollipops, while others are more like cones or cylinders. They can also be different colors depending on what kind of rock they are made of.
So next time you're outside on a windy day, take a look at some rocks and see if you can spot any ventifact knobs!
