Minerals are naturally occurring inorganic solids that have a crystalline structure and definite chemical composition. Soil is a mixture of decomposed organic matter and broken down rocks and minerals. Soil also contains important pore spaces that allow water and air to circulate.
Answer:
When the magma, a molten rock flows as lava at the planet's surface, the surface gets cooled after a long, this whole process cause formation of some kinds of minerals on that surface.
Explanation:
Magma and Lava both are types of molten rock. The underground molten rock is called magma while the exploded molten rock on surface is known as lava. When these rocks cools down they get solidified and form crystal rock structure. Cooled magma is called plutonic igneous rock and cooled lava is called volcanic igneous rock. These rock crystals are of different sizes and consist several minerals such as Silicon(Si), Sodium (Na), Potassium (K), Aluminium (Al), Iron(Fe), Magnesium(Mg), Calcium(Ca). Some rocks that forms minerals consist high amount of iron. The amount of minerals and elements in every rock can very depending on shape and size.
Answer:
El término archipiélago, en geografía, caracteriza una formación geológica que consiste en una cadena o grupo desarrollado de islas.
Los archipiélagos se encuentran generalmente en alta mar, aunque en algunos casos se encuentran adyacentes a grandes volúmenes de tierra. Los archipiélagos son a menudo volcánicos, se forman a lo largo de fallas oceánicas o en áreas con actividad volcánica activa, sin embargo, otros procesos geológicos como la deposición, desintegración y elevación del suelo están involucrados en el proceso de formación.
