What type of stresses broke Earth's lithosphere into plates?
The movement of convection currents in the mantle is believed to have caused the Earth's lithosphere to break into plates. These currents create stress within the lithosphere, leading to the formation of tectonic plates.
Most geologists think that the movement of earths plates caused by?
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
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.
How does the temperature and density drive the convection currents in the mantle?
Temperature differences in the mantle drive convection currents because warm material is less dense and rises, while cooler material is more dense and sinks. This movement creates a circular flow as the cooler material sinks and gets heated, while the warmer material rises and cools down. The density variations caused by the temperature differences are a key driver of convection in the mantle.
What are circulating currents in a fluid called?
Circulating currents in a fluid are commonly referred to as convection currents. These currents arise due to the movement of the fluid caused by temperature differences, which lead to the transfer of heat within the fluid. Convection currents play a significant role in processes like ocean currents and the movement of air in the atmosphere.
How convection currents are caused and how they move material in the mantle and lithosphere?
Because the mantle and lithosphere have gases or liquids that circulate
What causes the oceanic lithosphere to move away from the mid-ocean ridge?
it is caused by convection currents

What is a convection current caused by?
The liquid or gas which transfers the heat can circulate round and round between the hot and cold regions. The flow of liquid or gas is called a convection current. Convection currents are caused by changes in density.

Is convection currents caused by the heat of the core?
true
Which describes the convection currents that drive the motion of lithospheric plates?
Convection currents in the mantle, caused by heat from Earth's core, drive the motion of lithospheric plates. As the mantle heats up, it becomes less dense, rises, and then cools and becomes denser, causing it to sink. This continuous cycle of warm, rising material and cool, sinking material creates convection currents that move the lithospheric plates above them.
Plate motion is caused partly by magnetic reversals convection currents continental drift or volacnic hot spots?
Convection currents
What occurs as result of convection currents?
Convection currents occur when heated material rises and cooler material sinks, creating a circular motion. This process transfers heat and helps distribute it throughout the fluid or gas. In the Earth's mantle, convection currents drive plate tectonics, causing continents to drift and leading to geological phenomena like earthquakes and volcanic eruptions.
