The correct answer is - statistics tells something about objects that are not in the statistical sample.
Astronomers dedicate lots of time by looking through the telescopes in the sky, and they try to catch every possible detail they can notice, they gather the information and add that information to the statistics and make them more complete, thus they have more data and can make more precise assumptions about the objects in the universe.
B is most likely the answer. Hope this helps.
During the middle of the twentieth century, the Arabian countries flourished economically and they quickly started to change and to modernize. The reason why they were able to do so, and do it so quickly, was that they had the largest reserves of oil and natural gas. The oil especially was bringing in enormous amount of profit to them as it was the most demanded natural resource in the world. Because such enormous amount of money were coming in these countries, they were able to transform themselves very quickly, thus becoming countries where everything was modernized and of the highest standard. One thing that has to be noticed though is that these countries were not producing for themselves, nor did they developed any other industries, but pretty much everything was and still is imported.
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.
Answer:
Secondary economic activities involve the processing of raw materials (primary products). Examples would include turning timber into furniture and turning iron-ore into steel. Any factory can be seen as a system involving inputs (e.g. timber) processes (e.g. cabinet making) and outputs (e.g. tables and chairs).
