The clay minerals of sedimentary rocks are a good example. Clays are surface minerals, which form as feldspar and mica break down in the conditions at the Earth's surface. With heat and pressure they slowly return to mica and feldspar.Fluids are an important agent of metamorphism.Every rock contains some water, but sedimentary rocks hold the most. First there is the water that was trapped in the sediment as it became rock. Second is the water that is liberated by clay minerals as they change back to feldspar and mica.he foliated rock types that form under these conditions are called schist or gneiss, depending on their texture. Schist is finely foliated whereas gneiss is organized in wide bands of minerals. Contact or Local Metamorphism A type of metamorphism that is important in specific localities is contact metamorphism.
Although miniature sunflower varieties are about 2 feet tall, and giant varieties can grow over 10 feet tall, standard sunflowers are usually between 6 to 10 feet in height.Depending on the variety, sunflower plants started from seed can mature in 70 to 100 days.unflower Growth.
