Question

unit exam: thermal energy and earths processes
listen
which characteristic matches the correct layer of the earth?
crust: thin, solid outermost layer where humans live
lower mantle: high pressure and temperature, faster seismic waves
inner core: liquid iron and nickel due to intense heat
upper mantle: mostly peridotite, denser than crust rocks

Explanation:

The crust is the thin, solid outermost layer where humans live. The lower mantle has high - pressure and temperature and faster seismic waves. The inner core is solid iron and nickel due to extreme pressure, not liquid. The upper mantle is mostly peridotite and less dense than some crustal rocks in certain cases.

Answer:

A. Crust: thin, solid outermost layer where humans live
B. Lower Mantle: high pressure and temperature, faster seismic waves
