Question

what boundary type is responsible for creating new ocean floor?
a transform
b divergent
c convergent
d subduction

which layer of the earth is completely liquid?
a inner core
b crust
c outer core
d mantle

which scenario would most likely produce both earthquakes and volcanic activity?
a) two plates sliding past each other horizontally
b) an oceanic plate subducting beneath a continental plate
c) the formation of a rift valley
d) the collision of two continental plates

Explanation:

1. Divergent plate boundaries are where new ocean - floor is created as tectonic plates move apart and magma rises to fill the gap.
2. The outer core of the Earth is a liquid layer composed mainly of iron and nickel.
3. When an oceanic plate subducts beneath a continental plate, the subduction zone can generate both earthquakes due to the friction between plates and volcanic activity as the subducted plate melts and magma rises to the surface.

Answer:

1. B. Divergent
2. C. Outer Core
3. b) An oceanic plate subducting beneath a continental plate
