question 12 of 25
which action could be included in an accurate model of thermal convection in earths interior?
a. subduction where tectonic plates are moving apart from one another
b. seafloor spreading where convection currents meet
c. ridge formation where cold matter in the mantle is sinking
d. earthquakes where hotter matter is sinking beneath colder matter

Explanation:

Thermal convection in Earth's interior involves the movement of material due to density differences caused by temperature variations. Seafloor spreading occurs as a result of convection currents in the mantle pushing tectonic plates apart. Subduction is when one plate moves under another, not related to plates moving apart. Ridge formation is related to up - welling of hot material, not sinking of cold matter. Earthquakes are not directly related to hotter matter sinking beneath colder matter in the context of thermal convection models.

Answer:

B. Seafloor spreading where convection currents meet
