PLEASE HELP! 13 POINTS Explain by connecting the following terms: lava, seafloor spreading, ridge, plates. Also make sure to explain the significance of the directions of the arrows.​

The us is first  the  u.s. economy  remains the  largest in the world  in terms of nominal  gdp. however, the  u.s. economy  loses its spot as the number one  economy  to china when  measured  in terms of  gdp  based on ppp. in these terms, china's  gdp  is $23.19 trillion exceeds the  u.s. gdp  of $19.42 trillion

Ok so i just did that quiz and here are the answers: 1. how is continental crust different from oceanic crust? a. continental crust is more dense and contains a lot of basalt.b.continental crust is thinner and younger. < c. oceanic crust is thinner and younger.d.oceanic crust is thicker and contains a lot of granite.2. where do subduction zones often occur? a.where a continental plate is being split into two partsb.where an oceanic plate is moving toward a continental plate < c.where two oceanic plates are moving away from each otherd.where two continental plates are colliding3. at which type of boundary do lithospheric plates collide? a.convection boundariesb.contour boundariesc.gravitational boundariesd.convergent boundaries < 4. what is the best description of a convergent boundary? a.plates that move side by side past each otherb.plates that are attracted to each other by gravity  c.plates that move away from each otherd.plates that move toward each other < 5. how can mountain formation be described according to the theory of plate tectonics? a.as two continental plates collide along a convergent boundary, mountains are formed. < b.as a continental plate and an oceanic plate come together at a divergent boundary, mountains are formed.c.as any two plates meet at a fault line boundary, mountains are formed.d. as two continental plates move past each other at a transform boundary, mountains are formed.

The reason why i feel that the theory of plate tectonics is correct because scientists have found dinosaur bones of the same species in africa, asia, and in the americas. which means that they must have been together at one point in time. plate tectonics is also how the hawaiian islands were formed. as the plate hawaii is on was moving north west, magma would melt through the sea bottom and hardening. forming into the island chain. plate tectonics also explains the mariana trench. two plates were moving away from each other and made a giant crack in the ocean floor running 2,550 kilometers (1,500 miles)  long.
