Two very important elements found in the lithosphere are a. hydrogen and zinc b. oxygen and silicon c. carbon dioxide and sulfur d. platinum and gold

B beacuse if you look into the information alot will say oxygen and silicon

B. oxygen and silicon

Explanation:

The lithosphere is made up of the of the elements like the oxygen the silicon and is a terrestrial component of the crust and the part of the upper mantle and is hard and a rigid and of the layer of rocks and includes the oceanic basin and the crust which about 2.9 and 2.7 g / cubic cm.

I'm pretty sure it's c. extremely gradual but not 100% sure though.

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.
