<p>another Q: what are some benefits of volcanic eruptions?</p>
<p>Volcanos occur at subduction zones and mid-oceanic ridges (divergent), and hot spot.</p>
<p>what’s the cause of seasons</p>
<p>secondary succession… existing plants die out and new plants grow rapidly.</p>

<p>answer to next question: the tilt and rotation of earth’s axis?
Q: What is the population growth rate (%) formula?</p>
<p>(new pop- old pop)/ old pop

<p>Answers to previous questions:
volcanos produce new landforms (such as hawaiian islands) and increased soil nutrient levels produced from erosion of lava rock.</p>
<p>Seasons also are affected/caused by earths revolusion aroudn the sun.</p>
<p>Hmm I think that formula works too, but I learned that</p>
<p>population growth rate (%) = birth rate - death rate + immigration rate - emigration rate.</p>
