The correct answer is B Subduction. Subduction is the process by which an oceanic plate gets dragged under another plate and is eventually destroyed in the mantle. Subduction occurs at convergent margins where two oceanic plates collide or an oceanic and Continental plate collide. Oceanic crust is made of mainly of silica and magnesium which is heavier or denser than continental crust which is composed mainly of silica and aluminium.
The subducting plate melts producing excess magma giving rise to volcanoes along these margins.
Answer:
El país depende de la agricultura.
Explicación:
En Uganda, el 16% de la población es urbana y el 84% rural, las implicaciones sociales de esta proporción de poblaciones son malas para la economía porque más personas viven en las aldeas relacionadas con la agricultura y menos personas viven en las ciudades significa que menos personas trabaja en las industrias y oficinas. Debido a que hay menos gente en las zonas urbanas y más en las zonas rurales, el país todavía depende de la agricultura en comparación con las industrias, lo que conduce a una mala situación económica del país.
Answer:
C) when nuclear fusion begins in the core
Explanation:
- <u>The protostar is a main-sequence star that has a core temperature that exceeds abut 10 million K and is needed for the hydrogen to operate efficiently and the </u><u>length </u><u>of this process depends on nature and the stellar </u><u>mass</u><u>, as the huge massive star have a greater and bigger core and fusion takes fast.
</u>
- A protostar is also called as primitive star and represents the earliest phases of the process of the stellar evolution and takes place after it leaves form the main sequence star.
