2020-11-18 · MINERALS AND ROCKS THEIR PROPERTIES AND USES ROCKS ANDESITE: An igneous, volcanic rock, brown, greenish to dark gray that forms when magma of dioritic composition is erupted as lava flows or injected into fractures of volcanic vents and cones in the form of dikes and domes. The darker colored andesite can be mistaken for basalt in many cases.

2022-2-7 · If defined from a more scientific point of view, rocks are formed of a single or more mineral aggregated together naturally. It is created under great pressure and high temperature and then cooled for a prolonged time to take the form of a rock. Minerals like quartz are pure forms of solidified minerals that show up in the form of rocks.

The rocks might be made up totally of one mineral or different minerals, and their sizes are controlled by the cooling procedure. Igneous rocks are of two kinds, nosy and extrusive . Meddlesome igneous rocks are framed when the magma chills gradually under the world's outside layer and solidifies into rocks.

2020-4-17 · 4.3 Rocks and Their Properties Formation of Rocks: The Earth‟s crust called „Rock‟ is built up of different mineral aggregates. Rocks may be mono-mineral e.g. marble or poly-mineral e.g. granite. The mineral composition of a rock is almost similar but its chemical composition depends on kinds of constituent minerals.
