The numbers indicate the amount of air pressure, in millibars, that each line represents. These lines and numbers are necessary find out exactly where High and Low pressure systems are on the maps.
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.
Russia's ability to exert itself as a world power depends on profit to return the huge power that Russia hold in that area.

Answer:
The Moon's phases repeat every 29.5 days, but it's orbit around the Earth only takes 27.
Explanation:
Why? In that time, as our Moon moves around Earth, the Earth also moves around the Sun. Our Moon must travel a little farther in its path to make up for the added distance and complete its phase cycle.
