Answer:
B. Nation
Explanation:
B is the best answer here because culture, nationality, history, and ethnicity are all directly tied to one's country (nation). Territory and boundary are not as specific, and state is too narrow.
Tensional forces are present at divergent boundaries.
The Ming emperors made it their capital in 1421 and it remained China's capital till 1912 when the Manchu Empire fell and SunYat Sen turned China into a republic.
Slowly, deep underground
The igneous rock gabbro is coarse grained and non-vesicular. Both characteristics show that it is an intrusive igneous rock. Intrusive igneous rocks are formed below Earth's surface and slowly (because they're underground). When rocks are intrusive, they are are non-vesicular (no air pockets) because the air has had the time to escape because of the slow cooling time period. Intrusive rocks are also coarse because crystals had the time to form in the rock during that longer cooling time.
Ps. extrusive igneous rocks form rapidly at Earth's surface and basically have tge opposite characteristics for the opposite reasons (ex: vesicular cause air had little time to escape)
