The difference between mineral, metal and ores Many people confuse three completely different classes of substances (minerals, ores, and metals), so that metal becomes a mineral, and all minerals become ores. Minerals Minerals are inorganic solids (elements or compounds) that have distinct physical properties. Each substance has a known atomic structure and a fixed chemical […] Table of Contents Toggle MineralsOres materialsMetals
Astro geology, also known as planetary geology, is a fascinating field that focuses on the study of the geology of celestial bodies such as planets, moons, asteroids, and comets. This interdisciplinary science combines principles of geology, astronomy, physics, and chemistry to understand the formation, evolution, and composition of these extraterrestrial objects. The exploration of astrogeology […]

Continental accretion and plate tectonics are fundamental concepts in geology that help explain the formation and movement of Earth’s continents. Here’s an overview of both concepts: Continental Accretion: Continental accretion is the process by which continents grow in size over geological time scales. It involves the addition of new material to the edges of existing […] Table of Contents Toggle Continental Accretion:Plate Tectonics Model:
Basalt forms when magma cools and solidifies on the surface of the earth. It mainly occurs on the floor of the ocean as magma solidifies quickly coming in contact with cool ocean water. On the other hand, granite occurs above the ocean and makes up much of continental crust.
most of the ocean floor is basalt, and most of the continents are granite. Basaltic crust is dark and thin and heavy, while granite is light and accumulates into continent-sized rafts which bob about like corks in this “sea of basalt.” When a continent runs into a piece of seafloor, it’s much like a Mac truck running into a Volkswagon. Not very pretty, but at least there’s a clear winner. And the seafloor basalt ends up in pretty much the same position as does the VW – under the truck (or continent, as the case may be). This may seem like a drag for the basalt, but remember that it isn’t all that happy on the surface anyway, and this gives it the heat it needs to re-melt and try to complete the differentiation process which was so rudely interrupted at the spreading ridge. If successful and allowed to continue, what’s left behind is a “purified” magma with most of the iron, magnesium, and other heavy elements removed. When it cools, guess what forms? And the continental land mass just got a wee bit larger.

Basalt and granite are two different types of rocks that are formed through different geological processes.
Basalt is a dark-colored volcanic rock that is formed from the solidification of lava flows. When molten lava erupts from a volcano and flows over the surface of the earth, it cools and solidifies quickly, forming a fine-grained rock with a dense, uniform texture. Basalt can also be formed from magma that cools underground and solidifies to form intrusive rocks.
Granite, on the other hand, is an igneous rock that is formed from the slow cooling and solidification of magma beneath the earth’s surface. This process can take millions of years and allows for the formation of large crystals within the rock. Granite is typically composed of a mixture of minerals, including quartz, feldspar, mica, and hornblende, and can have a wide range of colors and patterns.
Both basalt and granite are important rocks that have many uses, including construction materials, decorative stones, and as a source of mineral resources.
