What is the most effective birth control pill? what is the least? can you get birth control without a parent’s convent if you are 16!

The most effective form of birth control is actually an IUD. All birth control is different, but an IUD is most effective. It just depends on what your menstrual cycle is like. I think if you're thinking about taking birth control, ask your parents about it so they can set up an appointment for you so a doctor can give you what would best work for you. I hope this helps!!

The answer to the question is c.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
