I’m not entirely sure what is being asked here, but the Tigris and Euphrates rivers is the only place in Egypt (besides the nile delta) with non-arid ground. That’s why most people live around there:
Water and carbon dioxide are usually the most abundant gases emitted during basaltic volcanism.
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
What happened when protesters in Syria stood up against the president was that the army repelled the protest with violent aggressions.
Sad but true. The government of Syria turned what first were pacific protests into a civil war that has severely damage the country and is the reason why thousands of people had decided to immigrate, creating an international migration crisis in the Middle East.
The original idea of the Syrian people was to peacefully take the streets to protest for better living conditions and democracy, as part of the events during the so-called "Arab Spring" of 2011. However, President Bashar al-Assad ordered to aggressively repel the protest, and since that day, the thing became horrible in places such as Aleppo, and many more.
Muslim countries such as Tunisia, Egypt, Syria, Morocco, and Libya took the streets in the Spring of 2011 to protest against their governments, demanding political changes that allowed people more freedom and better living opportunities. For instance, the protest in Egypt was so big that they could end with the dictator that governed Egypt for years, Hosni Mubarak.
Unfortunately in Syria, something very different happened.
<u>Answer:</u>
All of the above mentioned options can be used by scientists to date the sediment layer they are found in.
<u>Explanation:</u>
- Rock fossils, animal fossils, etc.found in the sediment layer can be used to determine the age of the sediment based on the period of the existence of that animal or the period of formation of the rock.
- Tree rings clearly exhibit the age of the tree. Hence, a sediment layer with the evidence of tree rings can tell the age of the sediment layer.
- An amalgamation of the data obtained from the animal growth rings and the period of existence of that specific animal species can be used to calculate the age of the sediment.
- The intensity of radioactivity left in the isotopes clarifies how old the isotope is.
- The age of mineral elements can be determined exactly with the help of processes like Potassium-Argon dating, Uranium-Lead dating, etc.
- Thus it would be easy to determine the age of the sediment layer containing mineral elements.
