When you cook spinach, its water content absorbs some of its water-soluble vitamin content, depleting it of those nutrients. However, 1.5 cups of cooked spinach contains 26.5 milligrams of vitamin C and a 10-ounce bag of raw spinach contains 79.8, so eating the entire bag cooked provides the same amount of that nutrient as eating a salad made with 1/3 of the bag. Folate, B vitamins and thiamine are also water-soluble nutrients in spinach.
The outer shell of the earth, the lithosphere, is broken up into tectonic plates. The seven major plates are the African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate and South American plate.
Earth's crust â the lithosphere â is composed of several major plates and many minor plates that change shape and position. Over time, these tectonic plates move, interact with each other, and are responsible for the formation of ocean basins, mountain ranges, islands, volcanoes, and earthquakes. The theory of plate tectonics is relatively new.
