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 earth spins around. one side faces the sun, one side faces space. the side facing the sun, we call daytime. side facing away is cooler and is nighttime. a day on earth is 24 hours, that’s how long it takes the earth to fully rotate one time. hope this !

Iam pretty sure that the answer is either a. -  it would the ecosystem become more stable. or it is d. -  the larger number of species would make the ecosystem more prone to disease.. 
i would go with d.
i hope this you!
have a nice day!
