It takes a long time for rock to break down into soil. what type of weathering occurs when acids come in contact with the rock

Explanation:

The rock then expands and is weakened. Sometimes rainwater contains acid (acid rain). When this comes in contact with rocks such as limestone, it slowly dissolves the rock. The most common forms of weathering are oxidation, hydrolysis and carbonation

( i am not so sure about my answer but i hope it will help)

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
