Question

a group of australian kangaroos moves out of the outback to a new area due to environmental changes. what term explains what the kangaroos are doing when they leave the outback? scattering roaming emigrating immigrating

Explanation:

Emigrating refers to leaving one's original habitat or area to move to another. The kangaroos are leaving the outback (their original area), which matches the definition of emigrating. Scattering is spreading out randomly, roaming is wandering without a fixed destination, and immigrating is entering a new area (not leaving the original one). Thus, emigrating is the correct term.

Answer:

emigrating
