Question

Which best supports the evidence that an asteroid collision may have caused caused the extinction of dinosaurs? (1 point)
O Rare metal on Earth called Iridium is found in layers where dinosaurs disappeared.
O Bodies of dinosaurs are only found in craters where asteroid collided.
O Dinosaur fossil remains are found at the bottom of a body of water.
O Many dinosaur skeletons are found in one particular rock layer.

Answer 1

The answer that best supports the evidence that an asteroid collision may have caused the extinction of dinosaurs is:

- Rare metal on Earth called Iridium is found in layers where dinosaurs disappeared.

This is because the presence of iridium in the same layers where dinosaur fossils disappear suggests a connection between the asteroid collision and the extinction event. Iridium is found in high concentrations in asteroids, so its presence on Earth could be a result of an asteroid impact.
