1 punto Un automóvil que se desplaza 100 m en línea recta y entra a una glorieta
que recorre cubriendo media circunferencia; considera que en ese punto
termina su recorrido. Si la glorieta tiene un radio de 50 m, ¿cuál fue su
desplazamiento?, y si en todo momento su rapidez fue constante, ¿cómo
fue su velocidad? *

The correct answer is  "c".  it is "c" because melting is an endothermic change, and endothermic get's energy from surroundings. 

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.
