Mantelströmmarna

Mantelströmmarna refers to the movement of material within the Earth's mantle. This convection process is driven by heat escaping from the Earth's core. Hotter, less dense material rises from deeper within the mantle, while cooler, denser material sinks from the upper mantle. This continuous circulation is fundamental to plate tectonics, influencing the movement of the Earth's lithospheric plates. The exact nature and complexity of mantelströmmarna are subjects of ongoing scientific research, with various models attempting to describe the patterns and dynamics of this slow but powerful movement. These currents play a crucial role in processes such as volcanism, earthquakes, and the formation of mountain ranges. The timescale of these convective currents is vast, spanning millions of years, making them a slow-motion engine shaping our planet's surface. Understanding mantelströmmarna helps geologists comprehend the Earth's internal structure and its evolution over geological time.
