Common Types of Rocks and Their Characteristics
Igneous Rocks
Formed from cooled and solidified magma or lava, igneous rocks are characterized by:
- Crystalline texture
- Interlocking mineral grains
- Examples: granite, basalt, pumice
Sedimentary Rocks
Formed by the accumulation and compaction of sediments, these rocks often feature layered structures and fossils. Key features include:
- Layering or bedding
- Presence of fossils or organic material
- Examples: sandstone, shale, limestone
Metamorphic Rocks
Result from the alteration of existing rocks under heat and pressure, leading to new mineral structures. Characteristics include:
- Foliation or banding
- Recrystallized minerals
- Examples: slate, schist, marble
Sample Quiz Questions and Answer Key Explanations
Question 1: What type of rock is typically characterized by visible mineral grains and a coarse texture?
- Igneous
- Sedimentary
- Metamorphic
Answer: Igneous. Coarse-grained textures are often seen in intrusive igneous rocks like granite, where slow cooling allows large mineral crystals to form.
Question 2: Which rock is most likely formed in a deep-sea environment and contains fossils?
- Sandstone
- Limestone
- Shale
Answer: Limestone. It often forms in marine environments from the accumulation of calcium carbonate from marine organisms and frequently contains fossils.
Question 3: A foliated metamorphic rock with shiny mineral grains is identified as:
- Slate
- Schist
- Gneiss
Answer: Schist. It exhibits pronounced foliation and shiny mineral grains due to the alignment of mica and other platy minerals during metamorphism.
