Answer:
please include the statements that the question is referring to
The convection currents are what causes the movement of the tectonic plates. These currents occur in the mantle layer. Basically, the convection currents are a circular movement of the magma in the mantle which is cause by the difference in temperature and density. The hotter magma moves up because it is less dense, while the cooler magma moves down because it is more dense. This movement continues all the time. The magma that moves up comes in touch with the crust above it. At certain places where the crust is thinner, or there are cracks, under the big pressure from the mantle, the magma manages to penetrate through it, filling up the gaps, and also pushing the plates away. As the plates are pushed more and more, their opposite ends collide with other plates, resulting in subduction, so the crust is getting into the mantle and melts, moving down in the mantle as it is becoming cooler and denser magma, and the process continues on and on.
Answer:
Explanation:
This is a clearer rendering of the text;
"The process of introducing changes in the way work is organized and the structure of industrial production is one of the consequences of the economic changes that began at the turn of the 1980s and 1990s were changes in the structure..".
It seems the text is referring to the events emanating after the industrial revolution, thus the statement is true.
The answer is
plants...
dams are man made...winds, they blows the soil away which causes erosion..rivers, they also cause erosion because when they flow, they carry the soil in the direction they r going n ump it somewhere else.
but plants, plants help breaks down soil n even makes more because the roots goes into the rocks n craks it up blah blah..and they hold the would from moving, like grasses do
I dont think my explanation was that good but I hope I helped a bit :)
