convection currents
The inside of Earth is structured in layers primarily due to the varying temperatures and compositions of the core and mantle. The core, which is extremely hot, generates heat through radioactive decay and residual heat from Earth's formation, leading to a molten outer core and a solid inner core. In contrast, the mantle, though hot, remains in a semi-solid state due to lower temperatures and pressures, allowing for convection currents that drive plate tectonics. This temperature gradient is crucial in shaping the geodynamic processes that govern Earth's geology.
Yes. Magma is underground molten rock.
Yes, the mantle is divided into the upper mantle and the lower mantle. The upper mantle is closer to the Earth's crust and is more malleable, while the lower mantle is beneath the upper mantle and is more solid due to higher pressure and temperature.
The core is the hottest part of the Earth, with temperatures reaching up to 5,700°C (10,000°F). The mantle is cooler than the core but hotter than the crust, with temperatures that range from about 500°C (932°F) to 900°C (1,652°F). The Earth's crust has the lowest temperatures of the three layers.
The lower mantle is one of the layers in the Earth's interior, located between the upper mantle and the outer core. It extends from a depth of about 410 to 660 kilometers below the Earth's surface. The lower mantle consists of solid rock material that experiences high pressure and temperatures.
A convection cell.
Convection currents form inside the Earth due to the temperature difference between the core and the mantle. The heat from the core causes the rock in the mantle to become less dense and rise towards the surface, while cooler rock sinks back down. This continuous cycle of rising and sinking rock creates convection currents that play a key role in driving the movement of tectonic plates.
The mantle and core are composed of the same material.APEX
Yes. Magma is underground molten rock.
Oh, dude, the inner mantle is definitely hotter than the outer mantle. Like, we're talking about temperatures reaching up to 4000°C in the inner mantle compared to a measly 500-900°C in the outer mantle. So, if you're looking for a hot spot, the inner mantle is where it's at.
The temperature of the Earth's mantle is higher than the temperatures of the outer layers, such as the crust, but lower than the core.
no, the core is divided into two different parts-the inner core and outer-core, the mantle is just one piece.
The four main layers of the Earth are the crust, the mantle, the outer core and the inner core. The temperature in the mantle is estimated to be about 1000 degrees Celsius. Temperature in the inner core can reach up to 3700 degrees Celsius.
The core is the hottest part of the Earth, with temperatures exceeding 5700 degrees Celsius. The mantle and crust are cooler in comparison, with temperatures gradually decreasing as you move towards the surface of the Earth.
The crust and solid brittle upper mantle make up the lithosphere.The plastic ductile upper mantle forms the asthenosphere.The mantle below the asthenospgere down to the boundary of the core forms the mesosphere.The core is split into the outer and inner, the difference being the outer core is in a liquid state and the inner core is a solid.
Yes, the mantle is divided into the upper mantle and the lower mantle. The upper mantle is closer to the Earth's crust and is more malleable, while the lower mantle is beneath the upper mantle and is more solid due to higher pressure and temperature.
there different cuz the mantle is on the out side, there similar cuz they both have a solid part
