RossRadiometric dating provides an estimate of the age of a rock or fossil based on the decay of radioactive isotopes within it. By measuring the ratio of parent isotopes to daughter isotopes, scientists can determine the elapsed time since the rock or fossil formed. This technique is commonly used to determine the age of Earth materials and artifacts.

How are the ages of rocks estimated?
The age of rocks is estimated using methods like radiometric dating, which measures the decay of radioactive isotopes in the rocks. By comparing the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the rock sample. Other methods, such as stratigraphy and fossil correlation, are also used to estimate the relative ages of rocks.
How can you determine the age of rock layers?
The age of rock layers can be determined using relative dating by studying the order of rock layers and the principles of superposition, cross-cutting relationships, and fossil succession. Absolute dating methods such as radiometric dating can also be used to determine the specific age of rock layers by analyzing the decay of radioactive isotopes in the rocks.
What is the best possible inference you can create from this information?
Further investigation is needed to draw any meaningful conclusions from the given information.
Determining how the sea floor changes over time has given scientists information about the?
Determining how the sea floor changes over time has given scientists information about the Earth's tectonic plate movements, the distribution of volcanic activity, and the history of sea level changes. Observing these changes helps scientists better understand the dynamic processes that shape our planet.
If ethanol has a density of 789 g then what is the mass of 225 g of ethanol?
The mass of 225 g of ethanol would be 225 g. The information given about the density of ethanol is not relevant to finding the mass of the given amount (225 g) of ethanol.
