Answer:
Granite changes into sandstone by means of weathering and erosion. Through the passage of time, fragments of granite are broken down into smaller pieces, or sediments, which are transported and deposited at the bottom of the oceans or rivers. These particles form layers of sand and pebbles that undergo compaction and cementation to create sandstone.

The statement is correct.
When a flood is giving a time-bonding term, such as the 100-year flood, in this statement, it means that it has been noticed that the floods from the particular river occur on approximately that much of a time span.
If there has been a flood recently, than it most probably means that there isn't going to be a flooding caused by that river for the foreseeable future.
Now, there's always exceptions, as the climate patters are changing constantly, and there's always surprises, but in general, in lot of regions of the world, there has been noticed a certain consistency in some natural occurrences.
