Answer:
Option (4)
Explanation:
Seismic P and S waves are generated during an earthquake that has the potential to propagate through the interior of the earth. P waves are also known as the primary waves and they move in a compression and extension way in their direction of propagation. S waves are shear waves. This P waves travel faster than the S waves and can travel in both solid as well as in liquid. Whereas the S wave can travel only through solids. They get absorbed when they reach the core-mantle boundary. These two waves are helpful in determining the epicenter of an earthquake by recording the arrival of these waves.
Hence, the correct answer is option (4).
The order of these periods is the Cretaceous period, Jurassic period, Triassic period, Devonian period, and Cambrian period.
The phrase "Cuddly Old Sheep Dogs Make Perfect Pets; They Just Crowd People Nearby Quietly" is one technique used to organize geological periods. In this phrase, the first letter of each word represents a period.
For example:
- Old starts with "o" and represents the Ordovician period
- Quietly starts with "q" and represents the Quaternary period
- Make starts with "m" and represents the Mississippian period
In this context, the order of the given periods from the most recent to the oldest one is:
- The Cretaceous period "crowd"
- The Jurassic period "just"
- The Triassic period "they"
- The Devonian period "dogs"
- The Cambrian period "cuddly"

This technique entails that community members execute various chores. Job specialization splits a community's labor into distinct tasks and allocates these jobs to various people. Job specialization results in increased competency as well as efficiency and production. As a result of the Neolithic Revolution's food surplus and population rise, job specialization developed.
The Contiguous United States does not include Alaska, Hawaii, or any other territories under the control of the United States. Alaska is unique among the US states as it is part of the North American continent, meaning it is attached via Canada, and so is part of the "Continental United States".
The answer is 3%
Explanation:
3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.
