These giant rocks are found
all over Karlu Karlu in northern
Australia. They balance on hilltops
and some are even stacked on top
of each other. How did they get
to be in such strange locations?
SHAPED BY NATURE
Rocks are worn down by water, wind, and the weather.
This erosion is responsible for incredible formations all
over the world, like the beautiful Antelope Canyon in
Arizona. Floodwaters slowly eroded the sandstone over
millions of years to create these amazing colorful sculptures.SCIENCE WONDERS
