Rocks and minerals
There are three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rock forms from cooled molten rock. Sedimentary rock forms from compressed and cemented sediment. Metamorphic rock forms from existing rock that is changed by heat and pressure. Rocks are made of minerals, and the types and amounts of minerals determine a rock's properties. Rocks and minerals can be assessed on the Mohs hardness scale to determine their strength.
Rocks and minerals[1]
There are three main types of rocks:
1) Igneous rocks form from solidified magma either below or above the surface.
2) Sedimentary rocks form from compressed and cemented sediment.
3) Metamorphic rocks form from existing igneous or sedimentary rocks that have been altered by heat and pressure.
minerals and rocks
Minerals are found in rocks and there are over 3000 known types of minerals. Minerals have different properties like color, hardness, streak, and luster that can be used to identify them. There are three main types of rocks: igneous rocks which form from cooling magma or lava, sedimentary rocks which form from compressed and cemented sediment, and metamorphic rocks which form from other rocks being subjected to heat and pressure below the earth's surface. Common rocks like granite, shale, and marble are used for construction materials, building monuments, and other purposes due to their unique properties.
Lesson 1 minerals and rocks notes
Minerals are the building blocks of rocks and come in over 3,500 varieties. They form rocks through the rock cycle of igneous, sedimentary, and metamorphic processes. Igneous rocks form from cooling magma, sedimentary rocks form through the compaction and cementation of sediments, and metamorphic rocks form from existing rocks undergoing heat and pressure.
Minerals and rocks
Minerals and rocks are natural, non-living materials. Minerals are the building blocks of rocks and give rocks their properties. There are three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form from cooled lava or magma underground or at the Earth's surface. Sedimentary rocks form from compressed and cemented sediments over millions of years. Metamorphic rocks were originally igneous or sedimentary rocks that were changed by heat and pressure within the Earth.
Rocks - Sedimentary
Sedimentary rocks form through the compaction and cementation of sediments. There are three main types: clastic rocks form from fragmented sediments like sand and gravel; chemical rocks form when dissolved minerals precipitate out of solution, like limestone and rock salt; and organic rocks form from the remains of once-living organisms, such as coal, petrified wood, and fossil-bearing limestone.
Rocks & minerals
Minerals are naturally occurring solid substances with repeating crystalline patterns. They form deep within the Earth through heat and pressure or near the surface when elements like oxygen, calcium, and carbon combine. Minerals have properties like streak, luster, and hardness that can be tested. Many common items are made from minerals, such as quartz in glass, diamonds in jewelry, and hematite in art. Rocks are composed of two or more minerals and do not have a crystalline structure. There are three main types of rocks: igneous rocks form from cooled lava or magma, sedimentary rocks form from compressed layers of sediment, and metamorphic rocks form from the alteration of existing rocks under heat and pressure.

Unit 3 rock slides
This document defines and compares different types of rocks, including their formation processes and compositions. Intrusive rocks form deep underground and have large crystals, while extrusive rocks form on the surface and have small crystals. Felsic rocks are lighter in color with high aluminum, while mafic rocks are darker with more iron and magnesium. The document also discusses sedimentary rocks like conglomerate, sandstone, and shale formed from clastic deposits, as well as chemical/evaporite rocks and organic rocks like coal. Finally, it defines metamorphic rocks as those changed by heat and pressure, distinguishing between foliated rocks with layered minerals and non-foliated rocks with massive, unlayered structures.
Rocks - Igneous
Igneous rocks form when magma or lava cools and hardens. They can form inside Earth's interior as intrusive igneous rocks or outside Earth's surface as extrusive igneous rocks. The texture of igneous rocks depends on the rate of cooling - slow cooling leads to large crystal grains as in intrusive rocks, while rapid cooling of lava produces extrusive rocks with small or no crystal grains.
Characteristics Of Rocks
Students learn to classify and group rocks according to their observable properties such as color, shape, hardness, and texture. Rocks record details of the Earth's formation and can be associated with different environments based on their composition and origin as sedimentary, igneous, or metamorphic rocks. Examples of rocks commonly found in buildings and cities include different types of sedimentary rocks, igneous rocks, and metamorphic rocks, even if they did not originally form in that location.
Minerals and Rocks
This lesson discusses what minerals and rocks are. It tackles various types of minerals and rocks. It discusses the rock cycle and how it produces the different kinds of rocks on our planet.
Igneous, Sedimentary, and Metamorphic Rocks
Igneous rocks form from the crystallization of magma. There are two main types - extrusive rocks that cool quickly at the surface, and intrusive rocks that cool slowly underground. Sedimentary rocks form through the lithification of sediments. Sediments are produced through weathering and erosion, transported, deposited, and cemented together over time under pressure. Metamorphic rocks form when rocks are subjected to high temperatures and pressures, causing their mineral composition and structure to change without melting. The rock cycle shows how rocks continuously transform between igneous, sedimentary and metamorphic types through geological processes.

Rocks can change between these types through geological processes in the rock cycle.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

- 2. Three types of Rocks •Igneous •Sedimentary •Metamorphic
- 3. Igneous Rocks •Formed by the cooling of Magma. Crystal size is determined by how slowly the magma cools. Some rocks of this type can be obsidian, basalt, and granite.
- 4. Igneous rocks formed inside the earth are called •Intrusive rock is formed when magma penetrates existing rock, crystallizes, and solidifies underground to form intrusions, for example plutons, batholiths, dikes, sills, laccoliths, and volcanic necks.
- 5. What 2 properties help classify igneous rocks? •Composition •Texture
- 6. Sedimentary Rocks •Formed when particles of broken rock and organic materials are pressed and cemented together to form new rocks. Sediments are mud, sand, pebbles, shells, bones, leaves, and stems. Some rocks of this type can be sandstone, limestone, and gypsum.
- 7. 4 sediments that make up sedimentary rocks. •A. Sandstone •B. Limestone •C. Quartzite •D. Gypsum
- 8. List 3 examples of sedimentary rocks. •Sandstone •Limestone •Gypsum
- 9. 3 categories used to classify sedimentary rocks? •Clastic •Organic •Chemical
- 10. What does Clastic sedimentary rock consist of? •pieces of broken up rocks
- 11. What does Organic sedimentary rock consist of? •pieces of material that was once living
- 12. What does Chemical sedimentary rock consist of? •rocks formed by inorganic processes •example: water evaporates to make a rock
- 13. Metamorphic Rocks •Formed when rocks are buried deep within the Earth and the large amounts of heat and pressure change the rock into something new. You can know the rocks are metamorphic when you see wavy bands in the rock. Examples, shale, gneiss, marble, and quartzite.
- 14. Metamorphic rocks require large amounts of these 2 properties to form •Heat •Pressure
- 15. 4 examples of metamorphic rocks •Shale •Gneiss •Marble •Quartzite
