The picture below shows the devils Millhopper sinkhole in Florida. The sinkhole was formed when:

A. River water eroded the soil
B. An underground cavern collapsed
C. A hurricane flooded low lying areas
D. Plant roots caused mechanical weathering of rocks

every el niño cycle is different. every year.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
