810 AA:10 Aa : 180 aa
810 AA: 180 Aa : 10 aa
O 10 AA : 810 Aa : 180 aa
O 500 AA : 500 aa
180AA: 810Aa : 10 aa

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.
