i think the miocene epoch spans the time from 23 million to 12 million years ago.

the correct answer is:

a population changes in response to a change in the environment.

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 : )

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint
