First, the foods that could be making it hard to poop: Consider your ABCs -- or applesauce, bananas, and cereal, Dr. Morton says. Too much of any of these, especially cereal, could cause constipation in your baby; also, keep an eye on dairy products that are popular first foods for babies, such as cheese and yogurt.
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. Image courtesy of the U.S. Geological Survey.
Convergent boundaries can be of three types: Subduction demonstration. Ocean-Ocean Convergence: If the plates moving toward each other are both made of oceanic crust, one of the plates will move downward, or subduct, under the other plate.This is called a subduction zone.his relative movement of the plates creates varying conditions at the plate edges, or boundaries. Geologists describe three basic types of plate boundaries: divergent boundaries, convergent boundaries, and transform boundaries.
