Shs11 earth and life science lesson 7
This document provides an overview of lesson 7 on minerals and rocks. It discusses the three main types of rocks - igneous, sedimentary, and metamorphic - and the processes involved in their formation. For each rock type, details are given on their origin, typical textures, classification schemes, and examples. The lesson also describes key concepts like magma, lava, intrusive/extrusive rocks, sedimentary features, and contact/regional metamorphism. Finally, students are assigned homework to research specific rock examples in more depth.

- 1. Lesson 7: Mineralsand Rocks Learning Competency: The learners shall be able to make a plan that the community may use to conserve and protect its resources for future generations. The learners will be able to classify rocks into igneous, sedimentary and metamorphic (S11/12ESIb-10). Specific Learning Outcomes At the end of the lesson, the learners will be able to 1. Classify and describe the three basic rock types; 2. Establish relationships between rock types and the origin and environment of deposition/formation; 3. Understand the different geologic processes involved in rock formation

- 6. Differentiate magma andlava. Magma is a molten rock material beneath the surface of the earth. Lava is molten rock material extruded to the surface of the earth through volcanic or fissure eruptions.
- 7. Describe plutonic orintrusive rocks and define the process of formation, the texture and give examples. •from solidified magma underneath the earth •gradual lowering of the temperature gradient at depth towards the surface would cause slow cooling/crystallization •Phaneritic texture •Examples: granite, diorite, gabbro

- 9. Describe volcanic orextrusive rocks and define the process of formation, the texture and give examples. • from solidified lava at or near the surface of the earth • fast rate of cooling/crystallization due to huge variance in the temperature between Earth’s surface and underneath • common textures: aphanitic, porphyritic and vesicular • examples: rhyolite, andesite, basalt • pyroclastic rocks: fragmental rocks usually associated with violent or explosive type of eruption. Examples tuff and pyroclastic flow deposits (ignimbrite)
- 11. Igneous rocks arealso classified according to silica content: felsic, intermediate, mafic and ultramafic. •felsic: also called granitic; >65% silica, generally light-colored •intermediate: also called andesitic; 55-65% silica; generally medium colored (medium gray) •mafic: also called basaltic; 45- 55% silica; generally dark colored •ultramafic:
- 13. Sedimentary rocks- •These arerocks that formed through the accumulation, compaction, and cementation of sediments. They generally form at surface or near surface conditions. • Sedimentary processes at or near the surface of the Earth include: weathering of rocks, sediment transport and deposition, compaction and cementation • Factors in sedimentary processes: weathering and transport agents (water, wind ice)
- 14. •Common sedimentary features:strata and fossils •Strata: >1cm is called bedding and anything less is called lamination; layering is the result of a change in grain size and composition; each layer represents a distinct period of deposition. •Fossils: remains and traces of plants and animals that are preserved in rocks
- 15. •Non-clastic / Chemical/Biochemical– derived from sediments that precipitated from concentrated solutions (e.g. seawater) or from the accumulation of biologic or organic material (e.g. shells, plant material). They are further classified on the basis of chemical composition. •Clastic/terrigenous - form from the accumulation and lithification of sediments derived from the breakdown of pre-existing rocks. They are further classified according to dominant grain size.

- 17. Metamorphic rocks •- rocksthat form from the transformation of pre-existing rocks (igneous, sedimentary, or metamorphic rocks) through the process of metamorphism. Metamorphism can involve changes in the physical and chemical properties of rocks in response to heat, pressure, and chemically active fluids. They are commonly formed underneath the earth through metamorphism
- 18. Contact metamorphism •• Heatas the main factor: occurs when a pre-existing rocks get in contact with a heat source (magma) •• Occurs on a relatively small scale: around the vicinity of intruding magma •• Creates non-foliated metamorphic rocks (e.g. hornfels)
- 19. Regional metamorphism •• Pressureas main factor: occurs in areas that have undergone deformation during orogenic event resulting in mountain belts •• Occurs in a regional/large scale •• Creates foliated metamorphic rocks such as schist and gneiss •• Non-foliated rocks like marble also form thru regional metamorphism, where pressure is not intense, far from the main geologic event
- 23. Enrichment •Assessment homework tobe submitted next meeting. Each student will do research on 3 rocks (one for each rock type). Included in the discussion are the following: history of formation, common environment of formation, common textures, common use of the rock and the localities in the Philippines where you can find them.
Editor's Notes
- #3 Bryce Canyon National Park /ˈbraɪs/ is a National Parklocated in southwestern Utah in the United States. The major feature of the park is Bryce Canyon, which despite its name, is not a canyon, but a collection of giant natural amphitheaters along the eastern side of the Paunsaugunt Plateau. Bryce is distinctive due to geological structures called hoodoos, formed by frost weathering and stream erosion of the river and lake bed sedimentary rocks. The red, orange, and white colors of the rocks provide spectacular views for park visitors. Bryce sits at a much higher elevation than nearby Zion National Park. The rim at Bryce varies from 8,000 to 9,000 feet (2,400 to 2,700 m). The Bryce Canyon area was settled by Mormon pioneers in the 1850s and was named after Ebenezer Bryce, who homesteaded in the area in 1874.[3] The area around Bryce Canyon became a National Monument in 1923 and was designated as a National Park in 1928.
- #4 Seneca Rocks is a large crag and local landmark in Pendleton County in the Eastern Panhandle of West Virginia, USA. It is the only "true peak" — a peak inaccessible except by technical rock climbing techniques — on the East Coast of the United States.[citation needed] One of the best-known scenic attractions in West Virginia, the sheer rock faces are a popular challenge for rock climbers. Seneca Rocks is easily visible from, and accessible by way of, West Virginia Route 28, West Virginia Route 55 and U.S. Route 33 in the Spruce Knob-Seneca Rocks National Recreation Areaof the Monongahela National Forest. The three highways converge in the hamlet of Seneca Rocks, which is named for the cliffs nearby.
- #5 Half Dome is a granite dome at the eastern end of Yosemite Valley in Yosemite National Park, California. It is a well-known rock formation in the park, named for its distinct shape. One side is a sheer face while the other three sides are smooth and round, making it appear like a dome cut in half.[3] The granitecrest rises more than 4,737 ft (1,444 m) above the valley floor.
- #23 Prepare in a Manila paper a flowchart template similar as the one on the right and post it in the board. Call students to fill up the flowchart by taping the flash cards in their proper location.
