Answers
Answer:
Hi friends,
continental crust:
varies in thickness
3.8 billion years old
rocky surfece, less than 1% of earths volume
oceanic crust:
solid, created by lava
constantly being created and destroyed
200 million years old
lithosphere:
rigid, brittle, breaks easily
consists of crust and upper mantle
rocky makes up tectonic plates
asthenosphere:
weak layer
flows like asphalt
softens rock, easily deformed
mantle:
semi-solid rock
80% of earths volume
high pressure/ heat
outer core:
liquid, 3000-5000*C
Generates magnetic field
inner core:
solid due to immense pressure
5000-9000*C
Generates magnetic field
❤️❤️❤️Have a great time❤️❤️❤️
