Which of these is not a primary component of Earth's mantle?
The core Heats up and makes Lava
The area nearest to the Earth's Core.
Almost 2900 km thick.
the temperature of the mantle can range up to 500 to 900 o C
The thickness of the Earth's mantle is about 2900 km and it's upper boundary is about 100km deep. There is a really cool cutaway drawing available by using the Wikipedia link.…

Earth's mantle is 2,900 km thick (1,800 miles)
Component of Earth 1. Atmosphere 2. Hydrosphere 3. Lithosphere 4. Biosphere
Yes. It moves in response to convection currents created by heat from the interior of the Earth.
It is about 3000 degrees celsius
Earth's mantle extends to a depth of 2890 km, making it the thickest layer of Earth. The pressure, at the bottom of the mantle, is ~140 GPa (1.4 Matm). 1.4 Matm = 1.4 million… atmospheres = 1.4 million x 14.7 = 20.58 million lbs per square inch
Convection currents in the mantle create plate tectonics.
Currents in the Earth's mantle are the result of temperature differences; hotter magma expands and is therefore less dense than cooler magma, and will rise, causing a convecti…on current. Heat in the Earth's interior is primarily caused by radioactivity.
convection occurs in the asthenosphere, which is located under the lithosphere. the inner core heats the liquid mantle and it circles and produces plate tectonic activity.
The primary cause of convection currents in Earth's mantle is believed to be that the temperature decreases the further from the core you go. The core of the earth is hott…er than the crust.
