how do the structure and composition of the earth cause goelogical activities ang physical changes
Answer (1)
Answer:The structure and composition of the Earth are fundamental to its geological activity and physical changes. The core, with its solid inner core and liquid outer core, generates heat and magma, influencing tectonic activity through convection currents and Earth's magnetic field. The mantle, especially the semi-fluid asthenosphere in the upper mantle, drives the movement of tectonic plates, leading to earthquakes and volcanic eruptions. The crust, both continental and oceanic, interacts with these processes; continental crust forms mountains and oceanic crust forms ocean floors, which are recycled through subduction. Tectonic plate interactions and volcanic activity shape the Earth's surface, while erosion and sedimentation continuously alter landscapes.
