The inner core.
Scientists believe that the Earth's inner core is most likely made of solid metals, primarily iron and nickel. This is supported by seismic wave data and studies on the Earth's magnetic field.
Geologists
Metals like indium, silver, and platinum are at risk of running out first due to their limited availability in the Earth's crust and high demand for technologically advanced products such as electronics and renewable energy technologies. Recycling and finding alternative materials are essential to mitigate the risk of depletion.
I believe that the answer you are looking for is Transition Metals.
Scientists believe that the molecule that came first in the evolution of life on Earth is RNA (ribonucleic acid).
Transition metals such as copper, silver, and gold are less reactive than alkali metals and alkaline-earth metals. These metals are less likely to react vigorously with water or air compared to alkali and alkaline-earth metals.
Scientists believe it does. Yes.
Scientists believe that the Earth is approximately 4.5 billion years old based on radiometric dating of rocks and meteorites.
Scientists believe that global warming is happening to the earth because of the greenhouse effect and carbon dioxide pollution in the atmosphere.
