The slow circulation of the plastic mantle in the earths asthenosphere occurs by what processes?

The slow circulation of the plastic mantle in the Earth's asthenosphere occurs mainly through convection, which involves the transfer of heat and material in response to differences in temperature and density. This process is driven by the heat generated from Earth's core and the radioactive decay of elements within the mantle, causing hot material to rise, cool, sink, and create a circular flow pattern in the asthenosphere.


What kind of heat transfer causes earths major wind patterns?

convection causes the heat transfer.


What is the name of the model that scientist use to describe air circulation in earths atmosphere?

The model that scientists use to describe air circulation in Earth's atmosphere is called the Global Circulation Model (GCM). These models simulate the interactions between the atmosphere, oceans, land surface, and ice to predict climate patterns and changes.


What happens to pressure as you move outward from earths core?

Pressure decreases as you move outward from the Earth's core. The farther you are from the center, the less mass you will have pressing down on your location. Mass that is underneath you (or in other words, closer to the center) does not press on you, only mass that is above will add to the pressure where you are.


How is heat transfer in the earths mantle related to the movement of the earths crust?

Heat transfer in the Earth's mantle drives the movement of the Earth's crust through the process of convection. As mantle material heats up, it becomes less dense and rises, causing the overlying crust to move. At the same time, cooler mantle material sinks back down, completing the cycle of heat transfer and driving the continuous motion of tectonic plates.
