I had this, i think it was conduction or plate tectonics.
Answer:
Minerals Available in Rock
Texture
Color
Chemical composition
Explanation:
There are different criteria that could be used to classify rocks that are igneous. These are:
1) Minerals Available in Rock: The minerals in a rock and their relative proportions in the rock mainly rely on the magma's chemical composition.
2) The Rock's texture: Rock texture largely relies on the magma's cooling history. Thus rocks with the same chemical composition and presence of the same minerals could have very distinct textures.
3) Color: A rock's color relies on the minerals and the size of the grain. Generally speaking, rocks containing lots of feldspar and quartz are light colored, and rocks containing lots of pyroxenes, olivines and amphiboles (minerals of ferromagnesium) are dark colored. But when applied to rocks of the same structure but distinct grain size, color can be misleading.
4) Chemical composition: The most distinctive characteristic is the chemical composition of igneous rocks. The structure generally represents the magma's structure, thus providing data about the rock's source.

South of the Alps lies the Apennine Peninsula.
Explanation:
The Alps are the largest mountain range on European soil. It is still up for debate are they the highest mountains in Europe or not, as there are still debates about the border of Europe and Asia in the Caucasus, where there are higher mountains than the Alps. This mountain range has been formed by the Alpine orogenesis, which has been triggered by the movement of Africa toward Europe. These mountains are considered to be young mountains, and they are still growing in area and height.
- The Alps are a natural barrier between Central and Western Europe north of them, and the Apennine Peninsula south of them.
- The Appennine Peninsula has its northern border totally surrounded by the Alps, which has led to the development of a unique culture, but also served as a good defense mechanism in the past.
- There are three countries located on the Apennine Peninsula, with Italy dominating almost all of it, and San Marino and Vatican occupying very small areas.
