What causes the convection cells to turn up at point a?
ice cream
Where is the pollen of a conifer?
the cell is open from the conifer and causes it to break up
During convection hot material do what?
During convection, hot material rises due to its lower density, creating a current that transfers heat from the hot material to cooler material. This process then causes the cooler material to sink and cycle back towards the heat source, creating a continuous convection current.
What causes convection currebts in the manlte?
Convection currents in the mantle are caused by heat from the Earth's core. As the core heats up the lower mantle, the material becomes less dense and rises towards the surface. Once the material at the surface cools, it becomes denser and sinks back down, creating a continuous cycle of movement known as convection currents.
What are some effects convection currents have on the world?
Convection currents play a crucial role in shaping Earth's climate by transferring heat from the equator to the poles in the atmosphere and oceans. They also drive the movement of tectonic plates, leading to phenomena like volcanic eruptions and earthquakes. In the Earth's mantle, convection currents are responsible for the movement of molten rock, which drives plate tectonics.
