What are the rocks made of

What are the rocks made of?

Once we got to know macrobudics, rock macrostructure, we wanted even deeper knowledge. We started looking for an answer to the question, what the rocks are made of. We discovered elements and chemical compounds, and more importantly, we started using them …

Rocks and minerals

The earth's crust is made of rock masses. The highest mountains in Poland - the High Tatras and the Karkonosze Mountains in the Sudetes made of granite, The Eastern Tatras and the limestone belt between Kraków and Częstochowa, the highest parts of Lysogória are made of quartzites, volcanic cones, rare in Poland, such as …

TRANSFORMED ROCKS

TRANSFORMED ROCKS

The third group of rocks, apart from igneous and sedimentary rocks, are transformed rocks (metamorphic). They were formed from pre-existing igneous or sedimentary rocks, which got into the deeper parts of the earth's crust, where they were transformed into new rocks. The main factors of transformation …

RESIDUAL ROCKS

RESIDUAL ROCKS

Rocks on the surface of the Earth are weathering, i.e.. mechanical and chemical deterioration due to the action of weather conditions. The material formed as a result of weathering may remain at the site of its formation or may be carried mainly by the waters of the streams …

MAGMA ROCKS

MAGMA ROCKS

The first material in the earth's crust are crystalline rock masses, mainly composed of silicates. They were formed by solidifying a hot silicate alloy, from deeper parts of the earth's crust. This silicate alloy is called magma, and the products of its solidification with igneous rocks …

Rocks

Rocks

The geological processes operating on Earth can be divided into two large groups: endogenous processes - taking place in the depths of the earth's crust and exogenous processes - taking place on its surface. Rock-forming processes belong to both of these groups. Rocks are formed for both …

The chemical composition of the earth's crust

The chemical composition of the earth's crust.

Rocks that make up the earth's crust formed as a result of long-term, rock-forming processes that take place sometimes for millions of years. During their history, they have undergone various displacements, so, that some formed deep in the earth's crust are now on the surface of the earth and …
