Okay, a paha is a type of landform that you might see in places like Hawaii or other volcanic areas. Imagine you're playing with play dough and you make a big long snake shape. Now, imagine that snake shape gets all wavy and bumpy. That's what a paha looks like, except it's made of rock instead of play dough.
Paha landforms are formed when lava flows quickly cool on the surface, creating a sort of hard crust. Underneath that crust, lava may continue to flow and move, creating bumps and ridges in the crust. Over time, erosion and weathering can wear away at the softer rock around the paha, making it stand out even more.
Sometimes, paha landforms can be a challenge to walk or drive over because they're so bumpy and uneven. However, they can also be really cool to look at because of the unique shapes and patterns they create in the landscape.
