The radioactive isotope content of a rock can be used to identify which property of the rock?.
Answer:
The radioactive isotope content of a rock can be used to identify the rocks age.
The radioactive isotope content of a rock can be used to identify the rocks age.
What is radioactive isotope?Any of multiple species of the same chemical element with varying masses whose nuclei are unstable and spontaneously emit radiation in the form of alpha, beta, and gamma rays to waste excess energy is referred to as a radioactive isotope, radionuclide, or radioactive nuclide.
The nuclear decay of radioactive isotopes is a clock-like process and thus a useful tool for determining the absolute age of rocks. These isotopes decay within the rocks according to their half-life rates, and the date at which the rock crystallized can be determined by selecting the appropriate minerals and measuring the relative amounts of parent and daughter isotopes in them.
Therefore the age of the rock can be identified by the use of the radioactive isotope.

Answer:If the the Earth were smaller than it is and the Alexandria-to-Syene distance were the same, the shadow of the vertical pillar in Alexandria would be longer.
Explanation:Hope this answers your question
If the Earth were smaller and the distance between Alexandria and Syene was similar, the silhouette of the vertical pillar in Alexandria would be longer.
How was the distance between Alexandria and Syene?Eratosthenes then measured the angle of a shadow produced by a stick at midday on the summer solstice at Alexandria and discovered it was around 7.2 degrees or 1/50 of a complete circle. He reasoned that if he knew how far Alexandria was from Syene, he could simply calculate the circumference of the Earth.
