Constructive plate boundaries
1) Convection currents in the mantle move the plates
2) 2 plates of oceanic crust diverge/pull apart e.g. North American and Eurasian plates.
3)
The rising magma forces the ends of the plate to push up and buckle.
This creates tensional cracks on the underside of the plates.
4) Magma is squeezed into the gap between the two plates and is cooled by the ocean to form new, solidified rock/basalt.
5) Rising magma forces its way through the tensional cracks and forms sub-marine shield volcanoes on the ocean floor.
6)
With repeated eruptions over millions of years they can grow until
they break the surface of the ocean and become volcanic islands e.g.
Iceland.
OK> well, first, memorize the countries. then use the map to test urself.I hpe u get a good geade!
The correct answer that would best complete the given statement above would be option D. LAHAR. <span>The mixture of water and rubble that flows from the slope of a volcano is a LAHAR. It is a fast moving flow. Hope this answers your question. </span>
The agricultural revolution in Britain was very important, if not the most important factor that led to the industrial revolution.
The reason for this is that with the agricultural revolution, the production on the farmlands increased significantly, and that trend was constantly going upwards. That led to a situation where there was much more production than what the country needed, so it had to be traded. But the trade of the crops was still limited, thus something new was needed, something that will enable the manufacturing of the goods, so that they can be preserved better and last longer, so that they can be traded further away. That economic pressure, led to multiple inventions, which resulted in the development of the industry, thus having the start of the industrial revolution.
