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.
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. Convergent Boundaries.he plates make up Earth's outer shell, called the lithosphere. (This includes the crust and uppermost part of the mantle.) Churning currents in the molten rocks below propel them along like a jumble of conveyor belts in disrepair. Most geologic activity stems from the interplay where the plates meet or divide.
