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.
I believe the answer to this is hydrosphere, lithosphere, and biosphere.
your answer would be D: crust and outer part of the mantel
<span>Answer:
The carbons on the closures are sp² hybridized, with a p-orbital for the 'second' bond in the twofold bond with their neighboring carbons.
They have those sp² orbitals covering with the s from the hydrogen, and they have a p covering in the pi bond with the neighboring carbon. They likewise have a sigma bond with the neighboring carbon I'll get to.
The center carbons each have two pi bonds with their neighbors, leaving sp hybridiaztion for the rest. So they have sp/sp² with the end carbons, and sp/sp with each other. (What's more, they likewise have p/p in the pi bonds).
So the total list is:
s/sp²
p/p
sp/sp²
sp/sp</span>
Answer:
Explanation:
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Some examples are quartzite and marble.
