The size shapes and arrangements of mineral grains in an igneous rock is known as texture or rock microstructure. It refers to the components found on a rock and how a rock is composed. The texture of an igneous rock varies differently; it can be either crystalline, fragmental, or glassy.
From altering the environment humans receive the benefit of multiple resources, such as wood which they receive from cutting down trees. Deforestation gives humans the benefit of having more land accessible for the public, as trees taken down by deforestation allows for humans to build public locations such as parks, and provides land for houses to be built on. Overall, altering the environment gives humans the benefit of having more resources, along with land that they are able to use for housing and livestock farms, which once again provide more resources for the public.

Metallic minerals become concentrated in liquid magma due to igneous, hydrothermal processes.
When magma forms first, it cools down and sink. The minerals concentrate at the top forming hydrothermal fluid.
