How does migration help animals survive and/or reproduce?

so they don't die and help them multiply

Explanation:

because they wont die if they move to a warmer place and help them reproduce because they move to a differ place that warm so there not dead so now they can get it on :)

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
