How to fill out classifying igneous rocks

1. To fill out classifying igneous rocks, you need to have a basic understanding of the different types of igneous rocks and their characteristics. Familiarize yourself with terms like extrusive, intrusive, felsic, mafic, and intermediate.
2. Start by collecting a variety of igneous rock samples. These can be obtained from rock shops, geological museums, or even outdoor locations where igneous rocks are commonly found.
3. Once you have your rock samples, examine them closely. Look for visible minerals, textures, and color variations. Note any crystals, pores, or vesicles present in the rocks.
4. Use a hand lens or magnifying glass to get a closer look at the rocks. This will help you identify the different minerals present and their overall composition.
5. Take note of the rock's texture. Is it fine-grained or coarse-grained? This can provide valuable information about the cooling history of the magma from which the rock formed.
6. Observe the color of the rock. Igneous rocks can vary in color from light to dark, and this can also provide clues about their composition and mineral content.
7. Perform a streak test on the rock samples. Rub the rock against a piece of unglazed porcelain tile and observe the color of the streak left behind. This can help identify the presence of specific minerals.
8. Use a field guide or reference book to help you identify and classify the igneous rocks based on their characteristics. Take into consideration factors like composition, texture, color, and mineralogy.
