It is also darker in color and denser. Continental crust is lighter and less dense. The crust is very thin compared to Earth’s radius.

Conduction from the core heats the lower mantle. Mantle convection bring hot material up toward the surface of the earth. It brings cooler material down toward the core.

Seismic waves let us know that the inner core is solid and the outer core is liquid. Metallic meteorites and the magnetic field also help us find out more about the core.

crust: Thin brittle outer layer of Earth.

oceanic crust: Portion of Earth’s crust that makes up the seafloor.

conduction: Process in which energy moves from a location of higher temperature to a location of lower
temperature as heat; only the heat moves, not the material.

convection: Movement of material due to differences in temperature.

peridotite: Dense, dark igneous rock that makes up the mantle.

Density: this depends in how hot or cold it is. The colder it is the more dense it is.

-the inner is believed to be as hot as the sun!

-Some parts of the mantle electrical conductivity, not seismic waves. ]]> 2018-03-23 15:47:05 UTC https://padlet.com/ayanna_desai/fabul0us/wish/245531722 ayanna_desai https://padlet.com/ayanna_desai/fabul0us/wish/245533656 2018-03-23 15:51:09 UTC https://padlet.com/ayanna_desai/fabul0us/wish/245533656 Citations ayanna_desai https://padlet.com/ayanna_desai/fabul0us/wish/245533720 https://www.nationalgeographic.org/encyclopedia/mantle/
