D. More education, later marriage, fewer children.
Explanation:
One of the most important factors when it comes to birthrates and thus family size is education. This goes for both genders, though it tends to be more pronounced at the women and their education level. To put it simply, the more educated the population is, the smaller the family size, the less educated the population is, the bigger the family size.
- When people are less educated, they start working earlier and very often marry very young. By getting married very young they have the first child very early and on top of it, they have much more time to have more children.
- When people are more educated, they finish studying later, focus on building a career because they have many more opportunities, thus they delay marriage. When they decide to get married it is later in their lives so usually, they don't really have enough time to have larger families.
- The education level of women is crucial. In every country where the women are highly educated the birthrates have dropped sharply. Basically, when women focus on their careers and delay marriage they found themselves in a situation to have a single child or to miss out on the period when they can have a child thus end up with none.
Compared to the surrounding material, mantle plumes rise towards the Earth's surface from the core-mantle boundary because they are hotter and less dense (3) than the surrounding material. A mantle plume is a large column of hot rock that rises through the earth's mantle. This plume is hot enough to cause the rocks in the lower lithosphere to melt. When the plume reaches the bottom of the lithosphere, it spreads out forming a mushroom shape cap. The lithosphere is then pushed up and stretched out. This forms magma chambers which feed the surrounding surface volcanos.
