The mechanical layers of the Earth are: Crust, Outer Mantle, Middle Core Crust, Mantle, Astheno layer, Lithocore, Inner core. Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core Crust, Techtonic Plate layer, Mantle, Lava Layer, Inner Core The crust is the outer most layer of Earth and is relatively thin compared to the overall size of the Earth. It can vary in depth from: (journal p.64) 500-800 miles deep 100-200 miles deep 40-100 miles deep 3-30 miles deep The inner core is made of iron and nickel and is solid due to the extreme pressure from the layers above it. (journal p. 64) True False The layer of Earth that includes the crust and upperpart of the mantle is the : (journal p.62) Lithosphere Mantle Tectonicsphere Asthenosphere The only liquid layer which slowly spins and is responsible for Earth's magnetic field is the: (journal p.64 & 65) Outer Core Lithosphere Crust Inner Core Which layer contains flexible, plastic like "deformable"rock? (journal p. 64) Crust Asthenosphere Lithosphere Mantle Temperature ___________ as you move towards the center of the Earth. Stays the same decreases varies increases What best describes the lower mantle? molten (melted) metal thicker, less flexible layer dense, solid metal ball dry land and ocean floor Pressure ______________ as you move towards the center of the Earth. decreases stays the same does not change increases Heat is transferred inside Earth by: microwaves convection radiation conduction |
