<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.
Answer:
Explanation:
The Earth is worse because of mining and this is because mining usually destroys ecosystems such as forests, rivers and makes the land unlivable for animals and humans alike. But reclamation mitigates this damage and after the mining is done they restore as much of the living conditions to the land or water as possible in order for the life to resume there or for humans to live there.
Answer:
By planting 2-8 trees for every tree cut.
Explanation:
It's common knowledge that trees grow slowly, and cutting all these trees makes endangerment and extinction very plausible. So planting many trees for every ONE cut will help the species.
