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.
Due to the high silica content, rhyolite lava is very viscous. It flows slowly, like tooth paste squeezed out of a tube, and tends to pile up and form lava domes.If rhyolite magma is gas rich it can erupt explosively, forming a frothy solidified magma called pumice (a very lightweight, light-coloured, vesicular form of rhyolite) along with ash deposits, and / or ignimbrite.In certain situations extremely porous rhyolite lava flows may develop.t flows slowly, like tooth paste squeezed out of a tube, and tends to pile up and form lava domes.
