How could scientists tell that the layer of iridium-rich clay around the world was deposited at the same time?
The Geologic time scale is how they are sure of which is found in the world In Asia they find a red clay deposit under a iron ore deposit In Africa they find a iridium-rich deposit under a red clay deposit In Canada they find this sequence: iron ore, red clay, iridium-rich In Europe they find red clay, iridium-rich, marble, granite When they piece together all of these sequences from around the world until they find a specific pattern in this example: iron ore, red clay, iridium-rich, marble, granite. However sometimes erosion or a drought or some other freak of nature happens that slightly changes the pattern.
