Answer:
The movements involved in plate tectonics acted like a giant conveyor belt for earths lithosphere and the Mid ocean ridges occur where mantle material rises upward, creating new seafloor crust and pushing plates apart.
Explanation:
How does this action explain the differences between seafloor crust and continental crust?
The movements involved in plate tectonics acted like a giant conveyor belt for earths lithosphere and the Mid ocean ridges occur where mantle material rises upward, creating new seafloor crust and pushing plates apart.
Main differences between sea floor crust and continental crusti is that oceanic crust and continental crust are less dense than the mantle, but sea floor crust is denser than continental crust. It also noticed that subduction occurs at ocean trenches, where dense seafloor crust pushes under less dense continental crust, thereby returning seafloor crust to the mantle. The subducting seafloor crust may partially melt, with lower density material melting first and erupting from volcanoes as new continental crust.
Answer:
HDI-human development index
the colum below shows schooling years(education part of HDI)-shows how "intelligent" a country is which indirectly relates to how much income is earned.
A very large range of countries are shown and as the poorer the country gets so does the level and amount of education
Explanation:
HDI is is a statistic composite index of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development.
