Answer 1
Answer: Sahara is a desert and deserts are hard to cross. Sahara is especially bad and potentially deadly: it's very dry and there is no water to be found for miles.

which igneous rock formed from magma that cooled slowly and is composed of 5% ampibole, 8% biotite 15% plagioclase feldspar, 37% quartz and 35% potassium feldspar

Answers

An igneous rock's composition would be felsic if it included significant amounts of quartz, potassium feldspar, and biotite.

Megascopic ally light-coloured igneous rocks are known as felsic igneous rocks. The felsic minerals that make up this colon are what give it its brilliant or bright hue. The elements Al, Ca, K, and Na make up felsic minerals, which are the principal minerals or the predominant minerals producing igneous rocks. There are three types of felsic minerals: feldspar, felspathoid (foid), and quartz. Quartz does not appear in rocks when foid minerals are present and vice versa. In addition, plagioclase and alkalis feldspar are subgroups of feldspar. The colour index of felsic igneous rocks typically ranges from 10% to 40%. When the silica content of felsic igneous rocks is greater than 66%, they are typically acidic in character.
