Question

1. in terms of size, how do these asteroids compare to the significant impacts throughout the earth’s history? type your answer... 3. are there any threats in this dataset? think about how you’d classify the risk levels of

Explanation:

To answer this, we consider known significant impacts (like the Chicxulub impactor, ~10 - 15 km in diameter) and typical asteroid sizes. Most asteroids in near - Earth space are smaller (e.g., many are <1 km), while major historical impactors were large enough to cause mass extinctions. So, generally, most current asteroids (not all) are smaller than the significant impactors of Earth's history (like the one that caused the Cretaceous - Paleogene extinction). But some asteroids could be comparable or larger, though those are rare.

Answer:

Most of these asteroids are smaller in size compared to the significant impactors (e.g., the Chicxulub impactor) throughout Earth’s history. However, there may be rare cases of asteroids with sizes comparable to or larger than some less - impactful significant historical impactors.
