Convection cells in the asthenosphere
WebJul 7, 2024 · Convection currents generated within the asthenosphere push magma upward through volcanic vents and spreading centres to create new crust. Convection currents also stress the lithosphere above, and the cracking that often results manifests as earthquakes. What will happen if there is no convection current in the asthenosphere? WebMantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface. [1] [2] The Earth's surface lithosphere rides atop the asthenosphere and the …

WebMay 2, 2024 · C.convection cells is the right answer Advertisement scasemere The movement of warmer and cooler mantle rocks creates pockets of circulation within the mantle called convection cells (currents). The force of the magma movement is thought to move the tectonic plates above. So the answer is Convection Currents/cells Brainliest … WebConvection in the molten rock of Earth's mantle drives the movement of the plates. Hotter material rises to the surface, while cooler material sinks toward the core. 3. Tectonic plates ride on Answer: mantle. Explanation: pwde ring airplane? 4. 10.

For liquids and gases, the convection cycle can happen … WebJan 19, 2024 · A. earth's natural process by which its lithospheric plates slowly move about because of movement in the asthenosphere B. a process by which the asthenosphere is heated and creates convection cells C. a dynamic process of the earth's interior by which the inner core produces a magnetic field
WebNov 27, 2024 · Explanation: The earth's core is extremely hot due to which the outer core is liquid in nature and it plays the most significant role in the plate tectonic movement, where the convection cells are formed in the mantle that drives the plates to move over the less dense layer of the asthenosphere. WebMar 1, 2024 · Above the transition zone, convection may be influenced by heat transferred from the lower mantle as well as discrete convection currents in the upper mantle driven …
WebSep 12, 2024 · Convection currents are part of what drives global circulation of the Earth's atmosphere. Combustion generates convection currents. The exception is that combustion in a zero-gravity environment lacks buoyancy, so hot gases don't naturally rise, allowing fresh oxygen to feed the flame.

Convection is the process by which less dense material rises and more dense material sinks. The former are said to be more “buoyant” than the latter, and … joe software edmontonWebSites characterized by upwelling of hot asthenosphere (the rising limbs of convection cells) have high heat flow (e.g., mid-ocean ridges). In contrast areas where the convection cells turn and sink back into the deep … joes of half moon bay restaurantWeb• Below the asthenosphere, hot mantle rocks rise from the core and then drop back downward after they cool slightly. This motion is called convection. Each area of rotation within the mantle is called a convection cell.
