Question

human historical growth and distribution
catastrophic events. the search for new frontiers,
including the exploration of planets like mars, may offer
growth opportunities, but challenges of sustainability and
distribution persist.
how did the spread of humans on the planet
change with the discovery of new continents?
clumping around resource - rich areas
wide distribution in deserts
no changes in the spread of humans
a tendency to avoid coastal areas

Explanation:

The discovery of new continents provided access to new resource-rich regions (e.g., fertile lands, minerals). Humans tend to settle and cluster in areas with abundant resources to meet survival and development needs, so their spread shifted toward clumping around these resource-rich new continental areas. The other options are incorrect: deserts lack sufficient resources for wide distribution; discovery of new continents clearly changed human spread; coastal areas are often resource-rich (e.g., fishing, trade), so humans did not avoid them.

Answer:

clumping around resource-rich areas
