Answer: Igneous Rock
Explanation: Radiometric dating is used to date rocks by measuring the decay of their composite materials. Stable isotopes remain the same over time while the nucleus of an unstable or radioactive isotope will decay to form other isotopes
.
Dating rocks using Isotopic methods uses the decay time of the isotope in the rock to assess its age. The accuracy of this method is assured by the fact that when these isotopes decay, they are retained in the rock. Isotopic dating is not very accurate in sedimentary rocks because they contain particles from older rocks.
The answer would be B.
Japan’s population has been at a steady decrease since as early as the year 2000 and the United States population has been at a steady increase dating back to 1790 from the research I have seen.
Rivers rise from higher slope and flow towards the lower due to the fact that there's more pressure the lower it goes.
<h3>What is a river?</h3>
It should be noted that a river simply means a large natural stream of water flowing in a channel into the sea.
In this case, rivers rise from higher slope and flow towards the lower due to the fact that there's more pressure the lower it goes.
