A, I just know its not any of the other ones
<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.
So your point doesnt become invalid.
Differing physical forces is the correct answer :)
Answer:
False
Explanation:
The increase in cloud-cover occurs with introduction of larger amounts of aerosols into the atmosphere. The increased amounts of carbon dioxide into the atmosphere will result in an increase of the greenhouse effect. Basically, the carbon dioxide is a greenhouse gas, having properties that enable it to trap the heat into the Earth's atmosphere. By doing so, the carbon dioxide will contribute to warmer atmosphere, thus warmer global climate. The effect of it will be that the Earth will have rise in the temperatures on global scale. The ice sheets will mostly melt, resulting in sea level rise. The rise of the sea levels will mean more ocean water, and less land, which in turn will create climate conditions that will be warm and wet in most of the planet.
