If it hits a single atom, a "product" can be broken. But only until it is a single molecule will a "molecule" be separated. Of starters, oxygen, H2O, always appears like oxygen in millions. But if you split it into smaller and lesser parts, say half, you can divide it only until you get 2 hydrogen and 1 oxygen. It's no longer water if you divide it further. It's going to be another matter.

11) Waves and currents are constantly beating on rock formations either on cliff faces that are between a rushing river, or the large rocks that the ocean waves crash onto. These sediments that are created by these examples of erosion are carried to new areas where, over time, they will begin to dorm new rock formations (Sedimentary rock)
12) Due to the loss of support that the groundwater acted as for the land that resided over on top of it, the ground began to collapse due to the lack of the water's support.
This climate is warm.
The animals in the tundra are strong to live in such an environment.
I don't know what the rest of that stuff is sorry.
