what is the composition, state of matter, and the location of the earths layers including the mesosphere, lithosphere, and asthenosphere. |
crust: composition/ oxygen, aluminum, iron, & silicon; State of matter/ solid; location/ the outer most layer which is contained in the lithosphere. mantle: composition/ magnesium, aluminum, & silicon; State of matter/ solid; location/ the layer of the earth between the crust & core. outer core: composition/ nickle & iron; state of mater/ liquid; location/ above the inner core & below the mantle. inner core: composition/ iron & nickle; state of matter: solid; location: surrounded by the outer core. asthenosphere: composition/ solid rock; state of mater/ solid; location/ the second outer most layer of the earth between the lithosphere, & the meosphere. mesosphere: composition/ part of the mantle; state of mater/ solid; location/ beneath the asthenosphere. lithosphere: composition/ made up of the riggid part of the mantle & the crust; state of mater/ solid; location/ the outer most layer of the earth & contains the crust & upper part of mantle.

How does density, temperature, & pressure change as you move from the lithosphere to the inner core? |
The temperature change is a difference because the inner core is the hottest layer of the earth. The lithosphere is solid, and the inner core is solid, & dense. The lithosphere has less pressure than the inner core because all the other layers are creating pressure for the inner core where the lithosphere is the outermost layer. |

|
What convection currents are deep inside the earth & how does it relate to plate movement? |
There are three different currents they are slab pull, ridge push, and convection currents. convection currents are deep inside the earth. this is similar to plate movement because it causes the oceanic lithosphere to move sideways. |

How do scientists learn about the interior of the earth? |
scientist must draw conclusions about the composition and other physical properties of the earth, from observations made on the earths surface. |
