For example, you can recover photos from a recovery mode iPhone. Launch the iPhone Data Recovery on your computer, and you will get the interface as follows. Choose the second recovery mode, and select your iTunes backup file which you want to recover from.
The sub-family of rocks that form from volcanic lava are called igneous volcanic rocks (to differentiate them from igneous rocks that form from magma below the surface, called igneous plutonic rocks). The lavas of different volcanoes, when cooled and hardened, differ much in their appearance and composition.olcanic rocks are usually fine-grained or aphanitic to glass in texture. They often contain clasts of other rocks and phenocrysts. Phenocrysts are crystals that are larger than the matrix and are identifiable with the unaided eye.
1 Aphanitic igneous rocks have a fine-grained texture and most of their crystals are too small to see with the naked eye. 2  You will need to use a magnifying glass to observe the crystals in aphanitic rocks. 3  Igneous rocks that form too quickly for crystals to form have what is called a glassy texture. An example of an intrusive rock is granite. 2  When magma is above the earth's crust, it is known as lava. 3  Extrusive rocks form through very fast cooling of lava above the Earth's surface. 4  Extrusive rocks have very small, almost microscopic crystals.
