Answer:
Shield volcanoes are built by many layers over time and the layers are usually of very similar composition. The low viscosity also means that shield eruptions are non-explosive. There are two types of lava flows, pahoehoe which is a ropy type of lava that flows easily (low viscosity).
There is no image so I’ll just explain the main 3:
Convergent: two boundaries are moving towards each other and usually create mountain ranges, or one is sinking below another another plate, cause volcanoes to appear
Divergent: two plates are moving away from each other, which created new land in between. Mostly is found on the sea floor
Transform: two plates are sliding past each other, usually appears with divergent boundaries
Hello!
The garbage patchs are a site with high concentrations of trash. They are formed by the ocean gyre, where the ocean have convergences zones forming a circle of currents. When the garbage join the circle, it can't go out, cause the currents make a kind of a permanent "wall".
We can locate garbages patchs in the South Atlantic Gyre, Indian Ocean Gyre and the South Pacific Gyre.
Hugs!
