The answer is transform/conservative plate boundary where the plates slide past each other without producing or destroying plate materials. One example is the San Andreas Fault of California.
The other two plate boundaries are destructive and constructive plate boundary seperately,in which constructive plate boundary will produce plate material given the rising convection current of magma, and the plates would move in opposite directions.
While the other destroy plate materials given the sinking convection current of magma,plates colliding with each other.
Hope it helps!
Germany is well known to have big problems with the aging population, and its very low fertility rate. This contributes to a highly deformed population pyramid, where the lowest part of the pyramid is becoming thinner and thinner, while the middle section is significantly increasing, as well as the upper part of the pyramid that becomes thicker and thicker because of the long lifespan in the country.
In the next twenty years, Germany will face stagnation in the number of population, and this will be because the minorities (mainly the Muslims) will be balancing the numbers because of their very high fertility rate. In the next 50 years, with this trend, we will witness a big drop in the numbers of the ethnic Germans, and very big increase in the numbers of the minorities (mainly Muslims) which will also contribute to the country's population to start to increase again.
If we will base our answer on Hertzsprung diagram, we
will see that mass and luminosity are directly related, which means, long lived
stars begin their lives with more mass and a larger amount of hydrogen fuel,
hence hydrogen is abundant before than now. They are more luminous during their
main sequence lives. Giant stars and supergiant
stars have great masses, so, they have greater luminosities.
