Tak for besvarelserne (: !
Jaa.. Altså er mig en smule uklart med forståelsen. Men nu har jeg prøvet at fikse lidt sammen.
Synes I, at min forståelse er korrekt?
Hvis I vil rette teksten lidt igennem, ville det være en ekstra bonus (: Tilføjelser og ideér modtages også gerne, med stor tak!

Describe the theory of minerals and rocks
A mineral is an inorganic solid, which has a definite chemical composition. It occurs naturally, and with atoms arranged in an orderly pattern. Most minerals are compounds (ect. Quartz, witch is a compound between silicon and oxygen). Minerals consisting of single elements are called native elements (ect. Cupper (Cu)). When different types of minerals are found mixed together (compounds and native elements), it is called rocks.
Examples of the processes are plate tectonics vulcanism, earthquakes, deposition and erosion and through the break down of the mountain ranges.
Rocks are found in Earth’s crust and mantle. Those stones of the mantle are mainly similar and are not often seen at the surface. Crust contains of many different types of minerals. These rocks can be classified according to the processes by which they are produced:
A) Sedimentary rocks (deposited rocks): are for example chalk, shales and sandstones. They are formed by sand, limestone or clay, which has been deposited in a particular geological environment. Over the time the material has been compacted to structure a hard rock by overlaying layers of rocks and sediments.
B) Magmatic rocks (vulcanic rocks): are for example basalts, granites and pophories. They are produced by crystallisation of melted rocks (melted by volcanic activity and from heat in the inside centre of Earth.).
C) Metamorphic rocks (Altered rocks): are for example quartsites (sandstones), marbles (limestone) and gnejses. Through the breakdown of the mountain range the rocks have become warm and soft devoid of melting, and have in this manner transformed form and shape. The different mineral grains are often found as stripes in the rocks.
