How is earths interior different than Mars interior?

Earth's interior is characterized by a differentiated structure, consisting of a solid inner core, a liquid outer core, a viscous mantle, and a solid crust, which contributes to tectonic activity and a magnetic field. In contrast, Mars has a simpler interior structure with a smaller, partially molten core, a mantle, and a thin crust, and it lacks significant tectonic activity and a global magnetic field. Additionally, Mars has experienced extensive volcanic activity in the past, but its geological activity is currently much lower than Earth's. These differences influence each planet's geology, atmosphere, and potential for habitability.
