What effect does pollution have on global temperatures? a. pollution causes acid rain, which leads to rising sea levels. b. chemicals in pollution end up in the oceans, causing water temperatures to rise. c. pollution decreases ozone, which prevents the earth from absorbing heat from the sun. d. many chemicals in pollution act like greenhouse gases, which trap heat in the atmosphere.
where are the answer choices?
most of the major earthquakes on the planet are located on the places where the boundaries of the plates are, or very close to it. some plate boundaries are more active than the others though, so the intensity of the earthquakes varies from place to place.
the most intense earthquakes seem to appear alongside the so called ''ring of fire''. this is actually where the boundary of the pacific plate is, where this plate is sunducting bellow the plates that surround it. because the pacific plate is a massive plate, with its subduction, it causes very big and lot of adjustments into the crust. because of these constant adjustments, there's earthquakes almost every second in some part of this plate's boundary. unfortunately, occasionally it causes devastating earthquakes, where lot of people lose their lives and huge material damage is caused as well.
there's four stages in the classical demographic transition model:
stage 1 - pre-transition
in this stage, the birth rates are very high, but also the life expectancy is very low, thus the growth of the population is slow.
stage 2 - early transition
in this stage, the birth rates are very high, but the life expectancy is increased, so the population grows rapidly.
stage 3 - late transition
in this stage, the birth rates decline slightly, and the life expectancy is a bit higher, thus the population growth is slowing down.
stage 4 - post-transition
in this stage, the birth rates are declined significantly, the life expectancy is pretty high, so the population is either growing very slowly, or it is declining.
