Answer:
C
Explanation:
Cold fronts move faster than warm fronts, they can catch up to and overtake their related warm front. When they do, an occluded front is formed.
Occluded fronts are signs of mature storm systems (i.e., those about to dissipate).
The type of occlusion that is the most common normally occurs in North America is called a cold-front occlusion and it occurs when the cold front forces itself under the warm front.
Answer:
C. When the oceanic lithosphere, which is more dense, sinks and pulls the plate with it
Explanation:
Slab pull and other mechanisms are responsible for the motion of plates. Every tectonic plate is driven by mantle convection.
- Convection is a form of heat transfer in fluids.
- It is as a result of differences in density and temperature values.
- The oceanic crust is denser and colder.
- As hot magma from deep within the subsurface rises and move through cracks, the oceanic lithosphere is drawn down and deeper.
- This cycling between the cold lithosphere and hot rising plumes provides the mechanism that drives plate motion.
All of them Plays an equal and important role to support life on Earth..
It causes the seafloor and outermost crust (the lithosphere) to bend and form a steep, V-shaped depression.
