Who Is The Scientist Who First Proposed That Thermal Convection In The Mantle Causes Continental Drift? Arthur Holmes: Harnessing the Mechanics of Mantle Convection to the Theory of Continental Drift. Who discovered convection in the mantle? Arthur Holmes (1890-1965) was an English geologist who made two important contributions to the development of geological ideas: the
What Process Drives Mantle Convection? The primary sources of thermal energy for mantle convection are three: (1) internal heating due to the decay of the radioactive isotopes of uranium, thorium, and potassium; (2) the long-term secular cooling of the earth; and (3) heat from the core. What is the process of mantle convection? Mantle convection
Which Best Describes The Shape Of A Convection Current? The shape of a convection current would be circular. Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over. Which describes convection current? A
Can Convection Occur In Both Liquids And Gases? Convection is the transfer of heat energy through the movement of fluid particles. Hence, convection cannot take place in solids, since the solid particles are not fluid. Thus, convection only takes place in liquids and gases. Can convection take place in liquids and gases? Convection occurs when
Why Do Global Winds Move In Convection Currents? All wind is caused by the uneven heating of Earth’s surface, which sets convection currents in motion, Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds. How are global winds like convection currents? Because convection cells are in
How Does The Sun Cause Convection Currents In The Ocean? Uneven heating of the earth can happen on a local level as well as a global level. During the day, air above land heats more quickly than air above the water. The warmer air is less dense and the cooler, denser air moves toward the
What Will Happen If There Is No Convection Current In The Asthenosphere? If for some reason convection stopped, air would not circulate, and weather would stop. Air wouldn’t flow over the waters, suck up moisture and then rain it out on land. Without this rain, all plants and crops would die. What would happen if
How Does Temperature Affect Convection Current? The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. Due to this temperature difference, the hot fluids tend to rise, whereas cold fluids tend to sink. This creates a current within the fluid called
Which Are Examples Of Convection Currents Brainly? marshmallows toasting over a campfire. a pot being heated by an electric burner. rice moving in a pot of water that is being heated. a radiator that emits warm air and draws in cool air. Which is an example of a convection currents? A simple example of convection
Where Is The Density Of The Mantle Greater? Where is the density of the mantle material greater at point A or point B? Answer: The density is greater at point C. At point C the magma si cooling , as the magma cools the particles move slower and the density increases and gravity pulls the
