Answer:
What do you need to be answered
Explanation:
First, preexisting rocks must weather/erode, forming the sediment that will eventually form the sedimentary rock. Then, that sediment must settle someplace, and over a long period of time, pressure begins to build. This causes the sediments to become compacted. After a long period of time (and a lot of pressure), the sediments cement together and form a sedimentary rock. In a nutshell, sedimentary rocks form through compaction, cementation, and eventually... lithification.

A water lily will have more stomata. A desert cactus will have very few stomata, because in deserts plants face water shortage so in order to avoid loss of water cacti have adapted to the desert environment by possessing few stomata.
