Question

How long does it usually take for a rock to be transformed from one rock type into another?

Answer 1

D) thousand to million years
this js because it has to erode and be weathered and the rest off it

Answer 2

D thousands to millions of years because The erosion of rocks takes really long.

For example: The waves attack the headland and then over a course of millions of years it transforms into a cave, then an arch, next a stack and lastly a stump.

Apart from erosion rock transformation can be affected by weathering.

I hope I've helped, I'm studying it in Geography in school at the moment so I'm pretty sure it's correct! ☺
