  MELCs At the endof the lesson, the student should be able to: • Identify common rock-forming minerals, using their physical and chemical properties (Module 3) • Classify rocks into igneous, sedimentary and metamorphic (Module 4)

  Rocks vs Minerals •Minerals are building blocks of rocks (Module 3) • Rocks are any naturally occurring solid mass of mineral aggregates (Module 4)

  Minerals as BuildingBlocks • Minerals may be defined as: SAN JUAN DE DIOS EDUCATIONAL FOUNDATION, INC. 2772-2774 Roxas Boulevard, Pasay City 1300 Philippines Hospital - Tel. Nos.: 8-831-9731/36; 8-831-5641/49 Website: www.sanjuandedios.org College - Tel. Nos.: 8-551-2756; 8-551-2763 Website: www.sjdefi.edu.ph Senior High School Department EARTH SCIENCE Semester: 1st S.Y. 2021-2022 • Take note of the five criteria and you will be able to identify substances whether they are minerals or #3 The substance must exist as a SOLID under normal conditions on Earth #2 The substance must be INORGANIC, not living or made from living things #4 The atoms that make up the substance must be arranged in an ORDERLY STRUCTURE #1 The substance must be NATURALLY OCCURING on Earth, not man-made #5 The substance must have a FIXED CHEMICAL FORMULA, made of specific elements Adapted from: https://www.iconscout.

  LESSON SUMMARY MINERALS (Module3) • Mineral are naturally occurring, inorganic, solid, with definite chemical composition and ordered structure • Mineralogist mostly used the physical properties of minerals for them to easily determine the identify of a mineral. • Minerals have a specific chemical composition and each mineral has its chemical formula.

  Rocks • Are anynaturally occurring solid mass of mineral aggregates • Classified into: • Igneous Rocks (Lesson 6) • Sedimentary Rocks • Metamorphic Rocks (Lesson 7) • [Pre-Ass] Rock Flowchart

  LESSON SUMMARY
• 20.
  LESSON SUMMARY ROCKS (Module4) • Igneous rocks are recognized by interlocking texture of the grains; presence of vesicles in extrusive igneous rocks; maybe dark-colored and heavy; and may display two grain sizes, one much larger than the other. • Sedimentary rocks are recognized by grains cemented together; the presence of fossils; light colored and light weight; and may display interlocking grains but is very light weight.
• 21.
  LESSON SUMMARY ROCKS (Module4) • Metamorphic rocks are recognized by interlocking texture of large grains; foliation (layering); banded light and dark colors; and ‘ching’ sound instead of a ‘chunk’ sound when tapped. • The rock cycle defined as a process in which rocks are continuously transformed between the three rock types.

  LESSON SUMMARY 2. Sedimentaryrocks are recognized by grains cemented together; the presence of fossils; light colored and light weight; and may display interlocking grains but is very light weight. 3. Metamorphic rocks are recognized by interlocking texture of large grains; foliation (layering); banded light and dark colors; and ‘ching’ sound instead of a ‘chunk’ sound when tapped. 4. The rock cycle defined as a process in which rocks are continuously transformed between the three rock types.
