<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.

Rhyolitic <span>magma causes powerful and explosive volcanic eruptions. The correct option among all the options that are given in the question is the third option or option "C". Andesitic volcanoes also erupt explosively but the correct choice would be Rhyolitic. I hope that the answer has come to your help.</span>
Answer:
48%
Explanation:
The relative humidity can be determined using a dry bulb and a wet bulb. The wet bulb temperature is usually lower than the dry bulb temperature. Hence, to determine the relative humidity, the wet bulb temperature is subtracted from the dry bulb temperature to determine the difference. Then the relative humidity is now determined using this difference and the dry bulb temperature.
Difference between dry bulb temperature and wet bulb temperature = 12°C - 7°C = 5°C
We locate the difference of 5 at a with a dry bulb temperature of 12°C on the table to get:
Relative humidity = 48%
