Question

Week Three: Intro to Rocks / Igneous Rocks1. From Activity 4.5 (p.121), place an "X" in the table to indicate what rock group is characterized by each of the processes and rock properties (hint: there is only one rock type for each process/rock property). (5 pts)Processes and Rock Properties Igneous Sedimentary MetamorphicLithification of sediment Intense heating (but not melting) Crystals precipitate from water Solidification of magma/lava Melting of rock Compaction of sediment Folding of rock Crystalline Foliated Common fossils 2. From Activity 5.5 (p.143), analyze and classify the igneous rock pictured below (sample 44 of your rock kit). Infer the origin of the rock based on its texture. (5 pts)-Mafic color index (% of mafic mineral crystals): -Would you describe the rock as mafic, intermediate, or felsic? -Texture present (i.e. phaneritic or aphanitic): -The name of this rock is:-Based on its texture, how did this rock form (i.e. intrusively or extrusively)? Use your textbook and rock samples to answer the following questions.3. Look at Bowen’s Reaction Series (figure 4.20 on p. 110 of your textbook). Lay your mineral samples on a white sheet of paper in the same arrangement as the minerals are presented in the figure, and take a picture. Paste the picture below

Answer 1

Step-by-step explanation:

1. Lithification of sediment = Sedimentary rock

Intense heating (but not melting) = Metamorphic rock

Crystals precipitate from water = Sedimentary rock

Solidification of magma/lava = Igneous rock

Melting of rock = Igneous rock

Compaction of sediment = sedimentary rock

Folding of rock = Metamorphic rock

Crystalline= Igneous rock

Foliated = Metamorphic rock

Common fossils = Sedimentary rock.
