What else can I help you with?
Where in the structure of the earth do convection currents occur?
The mantle.
What is the lower mantle made out of?
The earth's lower mantle is composed of an olivine mineral with a perovskite structure.
What is the thickest portion of the earth's structure?
The thickest portion of the Earth's structure is the mantle, which extends from the crust to the outer core. It is approximately 2,900 kilometers (1,800 miles) thick and represents about 84% of the Earth's total volume.
What are the internal structure of the earth?
the mantle the outer core and the inner core
Describe the structure of the earth?
The structure of the earth can be described by either the rheological or chemical properties. The structure of the earth is composed of the atmosphere, crust, continent, ocean, hydrosphere, ice cap, mantle, and the asthenosphere.
What are the components of earth structure?
core, mantle, inner crust, outer crust
What causes earth 's plates to move continuously?
Convection in the earth's mantle.
How does the structure of the earth relate to plate tectonics?
The structure of the Earth relates to plate tectonics as in the Earth structure there is the mantle layer, crust layer, inner and outer layer etc. The crust layer on top of the Earth is not a solid layer, the layer the broke up into big chunks which are now called tectonic plates.
What are the four main layers that make up Earth s structure?
The Inner Core (Centre of the Earth) The Outer Core (Second closest to the centre) Mantle (Third closest to the centre) Crust (What we live on)
Which system includes core mantle and crust?
The Earth's structure includes the core (inner and outer), mantle, and crust. The core is further divided into the inner core and outer core, while the mantle is divided into the upper mantle and lower mantle. The crust is the outermost solid layer of the Earth.
What are the main layers the form the earth's structure?
The Inner core, outer core, mantle, and crust.
What is the second layer of earths?
all was the best
