boundaries are where tectonic plates scrape past each other without moving apart or together.

New cards
Lithosphere
the rigid outer part of the earth, consisting of the __crust__ and upper __mantle__.
5
New cards
Mantle/Asthenosphere
the region of the earth's interior between the __crust__ and the core, believed to consist of hot, dense __silicate__ rocks (mainly __peridotite__).

New cards
Oceanic Crust
1. the relatively thin part of the earth's crust which __underlies__ the ocean basins. It is geologically young compared with the continental crust and consists of basaltic rock __overlain__ by __sediments__.

New cards
Continental Crust
