relative age
Relative age of the rocks and the Paleo environment.
The sea floor is young (the rocks are made at the mid oceanic ridges and spread out form there) while most of the continental rocks are older. This is because the continental crust floats on top of the oceanic crust and is therefore not recycled.
If you know the relative ages of two rocks, you can determine which rock is older and which is younger based on their positions in relation to one another. This is often established using principles such as the Law of Superposition, where in undisturbed layers, older rocks are typically found beneath younger ones. Additionally, you can infer the geological history and the sequence of events that led to the formation of those rocks. However, you won't know the exact age in years without absolute dating methods.
The study of strata is called stratigraphy. Stratigraphy can be used to determine an approximate age of fossils in rocks.
Radioactive dating techniques, such as radiocarbon dating or uranium-lead dating, provide an absolute age for rocks by measuring the decay of radioactive isotopes within them. This helps determine the actual age of rocks rather than their relative age.

It's age compared to the ages of other rocks.
Scientists used a variety of dating techniques including radiometric dating of rocks, study of fossil records, and analysis of the Earth's magnetic field to infer Earth's age. By studying the decay rates of radioactive isotopes in rocks and minerals, they were able to estimate that the Earth is approximately 4.54 billion years old.
The principle of relative dating helps geologists determine the age of rocks that are separated by distance. This principle states that in an undisturbed sequence of rock layers, the youngest rocks are at the top and the oldest rocks are at the bottom. By comparing the relative positions of rock layers in different locations, geologists can infer the relative ages of the rocks.
The age of disturbed rocks can be determined by methods such as radiometric dating, which measures the decay of radioactive isotopes in the rocks, or by studying the index fossils found within the rocks to determine their relative age compared to other layers. Stratigraphic principles can also help in determining the sequence of rock layers and their ages.
Index fossils are used to date rocks by correlating the fossils found in the rock layers with known ages of those fossils. Index fossils are distinctive, widespread, and lived for a relatively short period of time. By identifying these fossils in a rock layer, scientists can infer the age of the rock based on the age range of the known fossil.
determined by where it falls in comparison to other rocks in a sequence, using principles such as superposition and cross-cutting relationships. It does not provide an exact numerical age but gives an idea of whether it is older or younger than surrounding rocks.
Gorillas and humans have different levels of intelligence. While gorillas are intelligent animals, their cognitive abilities are not as advanced as those of humans at any age. Humans have a higher level of intelligence and cognitive development compared to gorillas at all stages of life.
i think rocks age becauce of the carbon inside of them.
If you mean, what kind of tools did humans use in the Paleolithic age, mostly sticks (some of which were on fire), arrows & bows, and rocks chipped into arrowheads. If you mean kinds of human were living in the Paleolithic age, that depends on whether you consider other animals in our genus to be human.
The age of a rock can be determined through radiometric dating techniques, comparing the ratios of certain elements in the rock to known decay rates. By analyzing the age of the rock in relation to the ages of other rocks in the surrounding area or in similar geological contexts, scientists can establish the relative age of the rock within the geological timescale.
