2 which statement best describes how a convection current is made? a rock magnetism changes as rock layers melt under heat and pressure causing convection currents. b hot magma rises and cold magma sinks in the mantle causing a convection current. c hot crust goes down and cold outer core goes up causing a convection current.

2 which statement best describes how a convection current is made? a rock magnetism changes as rock layers melt under heat and pressure causing convection currents. b hot magma rises and cold magma sinks in the mantle causing a convection current. c hot crust goes down and cold outer core goes up causing a convection current.

Answer

Brief Explanations:

La convección en la Tierra ocurre cuando la magma caliente en el manto se eleva y la magma fría se hunde debido a diferencias de densidad causadas por la temperatura. La opción A se refiere a la magnetización de las rocas y no a la convección. La opción C es incorrecta ya que no es la corteza caliente la que desciende y el núcleo externo frío el que sube en el proceso de convección en el manto.

Answer:

B. Hot magma rises and cold magma sinks in the mantle causing a convection current.
