Geography - rock formation rock cycle - GCSE
This document provides information about three main types of rocks: igneous, sedimentary, and metamorphic. It describes how igneous rocks form from molten rock, either on the surface as extrusive rock or below the surface as intrusive rock. Sedimentary rocks form from compaction and cementation of sediments, in clastic, organic, or chemical forms. Metamorphic rocks are any rocks transformed by heat and pressure, either in foliated layers or nonfoliated randomly arranged grains. The document explains the key characteristics and formation processes of each rock type.
5.1 the rock cycle
There are three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form from cooling magma underground or lava on the surface. Sedimentary rocks form from compressed fragments of other rocks or organic matter. Metamorphic rocks were already existing rocks that underwent extreme pressure, heat, or chemical changes and altered form. Rocks are constantly changing between these types through the rock cycle as geological forces cause one type of rock to transform into another over long periods of time.

Ch04 igneous rocks-fall2007
This document discusses the formation of igneous rocks. It explains that igneous rocks form from the crystallization of magma or lava as it cools. Magma originates from the partial melting of rocks in the Earth's mantle or crust due to increased heat, decreased pressure, or the presence of volatiles like water. As magma cools, minerals crystallize out in a predictable order described by Bowen's Reaction Series. The composition of magma evolves as it cools through processes like fractional crystallization. Igneous rocks range from basalt to andesite to granite depending on their origin and evolution.
Lecture on petrology
Petrology is the study of rocks and the conditions in which they form. There are three main branches corresponding to the three rock types - igneous, metamorphic, and sedimentary. Igneous rocks form from solidification of magma or lava, and can be intrusive (plutonic) or extrusive (volcanic). Classification is based on mineralogy, texture, and chemical composition.
Ch 11 diversification
The document discusses various processes of magmatic differentiation, including crystal-melt fractionation, physical separation of immiscible melts, and fluid-melt separation. It proposes that compositional convection within a boundary layer along the walls and top of a magma chamber can lead to in situ crystallization and development of compositional stratification faster than diffusion alone. As the magma cools and crystallizes from the margins inward, a gradient in the extent of crystallization develops. This produces a gradient in liquid composition, with more evolved liquids at the margins rising and spreading laterally beneath a stagnant cap, contributing to stratification.
Chapter 7 metamorphic rocks
This document summarizes key concepts from a chapter about metamorphism from the textbook Essentials of Geology. Metamorphism occurs when rocks undergo changes to their texture, mineralogy, and chemistry due to changes in temperature, pressure, and reaction with fluids. There are several processes involved, and metamorphic rocks exhibit distinctive properties based on the conditions they form under. Different metamorphic environments and intensities can produce different rock types. Index minerals are used to determine metamorphic grade.

Igneous rocks
There are three main types of rocks classified by how they are formed. Igneous rocks form from melted rock and can be either extrusive or intrusive. Extrusive igneous rocks cool quickly on the surface to form fine crystals like basalt and obsidian, while intrusive igneous rocks cool slowly inside the Earth to form larger crystals such as granite and gabbro. The size of crystals in igneous rocks depends on whether they cool quickly on the surface or slowly underground.

Igneous rocks 2011acloutier copyright
Igneous rocks form from the crystallization of magma either underground, forming intrusive igneous rocks like granite, or on the surface as extrusive igneous rocks like lava. Magma is molten rock located either underground or on the surface before it cools and becomes igneous rock. The composition of magma can be basaltic, granitic, or andesitic depending on its silica and water content. Igneous rocks are classified based on their mineral composition and texture, and can provide clues about the cooling environment.
Rock Cycle PowerPoint
The document discusses the three main rock groups: igneous, sedimentary, and metamorphic. Igneous rocks form from cooling magma, either underground (intrusive) or above ground (extrusive). Sedimentary rocks form through the compaction and cementation of sediments. Metamorphic rocks are formed from existing rocks undergoing heat and pressure without melting. The rock cycle diagram shows how rocks continuously change between these three types through various geologic processes.
Metamorphic Rocks
Metamorphic rocks are formed from existing rocks through recrystallization caused by heat and pressure, without melting. There are two types of metamorphism: regional metamorphism occurs over large areas with extreme heat and pressure, as in mountain building; contact metamorphism occurs only near intrusions and does not melt the rock. During metamorphism, new mineral crystals form and original structures can be distorted, resulting in foliated rocks like schist. Limestone becomes marble, sandstone becomes quartzite, and shale becomes slate through metamorphism. Fossils are not found in metamorphic rocks as the heat and pressure would destroy them.
Intrusive rock
This document discusses igneous rock classifications and Bowen's reaction series. It begins by classifying igneous rocks based on their silica content into felsic, intermediate, mafic and ultramafic compositions. It then explains Bowen's reaction series, which showed that minerals crystallize from magma at different temperatures in a predictable order. Certain minerals tend to form together based on their crystallization temperatures. The document also discusses how igneous intrusive bodies like sills, dikes, batholiths and stocks form underground from crystallizing magma.
Plate tectonics and magma genesis
The document discusses plate tectonics and magma genesis. It describes how the Earth's crust is divided into 12 major plates that move in various directions, causing them to collide, pull apart, or scrape against each other. It also explains that magma can only be created at plate boundaries where there are significant local changes in pressure and temperature. The three main types of plate boundaries are divergent boundaries, where plates separate and new crust is formed; convergent boundaries, where plates collide and one slides under the other; and transform boundaries, where plates slide past each other.

The document discusses petrology and igneous rocks. It defines petrology as the branch of geology dealing with various aspects of rocks, including their formation, classification, properties and structures. It describes igneous rocks as those formed from molten material (magma or lava) that has cooled and crystallized. Igneous rocks are divided into three types based on where they form - volcanic, hypabyssal, and plutonic rocks. Texture in igneous rocks is determined by the size, shape and arrangement of mineral constituents, and can be described based on crystallization, granularity, and fabric.

The document discusses the Earth's internal structure and how it is studied using seismic waves. There are three main layers within Earth - the core, mantle, and crust. The core is the innermost layer and makes up about 1/3 of Earth's mass. The mantle is the middle layer and comprises about 2/3 of Earth's mass. The crust is the outermost layer and is a very small fraction of Earth's total mass. Seismic waves generated by earthquakes travel through Earth at different speeds depending on the material, allowing scientists to map its internal structure.

This document provides an overview of igneous rocks and magma. It defines igneous rocks as those formed from cooled magma. Magma forms from melting of rock in the crust or upper mantle, driven by mechanisms like pressure release, heat transfer, and addition of volatiles. Magma composition varies based on its source and processes during ascent, with the main types defined by their silica content. Composition controls eruption style, from explosive for silica-rich magmas to effusive for mafic ones. Igneous rocks form intrusively underground or extrusive at the surface, exhibiting different textures based on their cooling rate.
Igneous Rocks/EPCC/LM4
Igneous rocks form from the cooling and solidification of magma or lava. They can be intrusive or extrusive, depending on where the magma cools. Intrusive igneous rocks cool slowly underground, resulting in large mineral grains, while extrusive rocks cool rapidly at the surface, resulting in small mineral grains or a glassy texture. The mineral assemblage and texture of an igneous rock provides clues about its composition and conditions of formation. Bowen's reaction series describes the order in which minerals crystallize as magma cools.
Classifications of igneous rocks
Igneous rock forms through the cooling and solidification of magma or lava. It is classified based on several properties including genesis, texture, color, and chemical composition. Based on genesis, igneous rocks are classified as plutonic (cooled at depth), hypabyssal (cooled at shallow depth), or volcanic (cooled on the surface). Texture classifications include phaneritic, aphenitic, porphyritic, and poikilitic. Color classifications are based on the percentage of mafic minerals and include leucocratic, mesocratic, melanocratic, and hypermelanic. Chemical composition classifications include peraluminous, metaaluminous, subaluminous, and several

This document discusses petrology, which is the branch of geology that studies rocks and the conditions under which they form. It describes the three main classes of rocks - igneous, sedimentary, and metamorphic - and their key characteristics. Igneous rocks form from cooling magma, either deep underground as plutonic rocks or at the surface as volcanic rocks. Sedimentary rocks are formed from the lithification of sediments. Metamorphic rocks form from the alteration of existing rocks through heat, pressure, and chemically active fluids in the Earth's crust.
Rock Cycle
The document discusses the rock cycle, which is a model that illustrates how the three main types of rocks - igneous, sedimentary, and metamorphic - are formed through natural geological processes and change over time. The rock cycle shows how rocks are related through weathering, melting, pressure and heat. It also explains that the law of conservation of matter applies, as the elements that make up rocks are just redistributed during the changes in the rock cycle, and matter is never created or destroyed.

This document provides information on igneous rocks, including their classification. It discusses igneous rocks being divided into plutonic (coarse-grained intrusive), volcanic (extrusive), and hypabyssal rocks based on cooling conditions. Classification is also based on mineralogy and chemistry, notably the silica content, which divides rocks into felsic, intermediate, mafic, and ultramafic compositions. Textural properties like grain size, mineral proportions, and cooling structures are also used to identify and categorize different igneous rock types. Common examples of each rock class are provided.
Igneous rocks
Rocks are divided into three major groups: igneous, sedimentary, and metamorphic. Igneous rocks form when magma cools and solidifies. Magma comes from deep below the Earth's surface and is composed mainly of oxygen, silicon, aluminum, iron, sodium, magnesium, calcium, and potassium. When magma reaches the surface it is called lava. Igneous rocks can be extrusive or intrusive, with extrusive rocks like lava flows cooling at the surface and intrusive rocks like dikes and sills cooling below the surface. Texture and structures like vesicles and phenocrysts provide clues to how quickly igneous rocks solidified.
Metamorphism of different Rocks
This document summarizes the metamorphism of different rock types including ultramafic, mafic, pelitic, and calcareous rocks. Ultramafic rocks like peridotite and serpentinite can transform into serpentine, anthophyllite, olivine, and pyroxene minerals. Mafic rocks like basalt metamorphose into amphiboles and chlorite at low grades and amphibolite at intermediate grades, and granulite at highest grades. Pelitic rocks contain chlorite, muscovite, quartz and albite. Calcareous rocks like limestone coarsen but change little, while impure limestone forms diverse calcium-magnesium-sil

Rocks form in different ways and are classified based on their composition and how they are formed. The rock cycle shows how rocks continuously change over time through geological processes like weathering, erosion, deposition, and metamorphism. Scientists use various methods to determine the relative and absolute ages of rocks, including analyzing rock layers and fossils. Index fossils in particular allow scientists to relatively date rock layers based on the period of time specific fossils existed.

Hope eternal by John Hardy
This document contains several quotes and passages from the Bible about God's love for humanity. Some key points include:
- God loves the world so much that he gave his only Son (John 3:16)
- Nothing can separate us from God's love (Romans 8:38-39)
- Those who believe in Jesus will have eternal life and not die (John 3:16)
- God rewards those who seek him by settling for nothing less than a relationship with Jesus himself. (Max Lucado quote)
The rockcycle
The rock cycle describes how rocks are continuously transformed between three main types - igneous, sedimentary, and metamorphic rocks - through geological processes such as erosion, deposition, burial, melting, and crystallization. Igneous rock is weathered into sediment and deposited to form sedimentary rock, which is then buried and altered by heat and pressure into metamorphic rock. Metamorphic rock can be melted into magma and erupt as new igneous rock, restarting the cycle.

Regulations in IoT - Innovation Stifle or Urgent Need
It is the Wild Wild West in the world of ‘Things’. We can make anything smart. Everything from a trash can, a diaper or a wall is now a smart thing.
With so many applications, there are as many risks.
Governments, Std. bodies across the world are grappling with a question - do we need any regulations? Or is it going to stifle innovation?
One may think regulations just don’t work here. That may be true. But with no regulations, we may be facing serious problems.
Will we end up creating crippling constraints for innovation? Will it be abused so much that consumers shun adoption?
We debate whether it makes sense to introduce regulations or let the market forces correct the problems. Or is there any other options?
Final draft
Herbal medicine has a long history of use and is still commonly used today, including during pregnancy. Many pregnant women use herbs to treat conditions like morning sickness, menstrual disorders, and labor pains due to their perceived efficacy and safety. However, some herbs can be harmful during pregnancy and should be avoided, like those that cause uterine contractions. Pregnant women must carefully research any herbs they consider using and consult their healthcare providers due to risks from potential toxicity. Overall herbal medicine requires caution during pregnancy and reliance on certified practitioners rather than internet or media sources alone.

Natural selection occurs through a 5 step process: 1) Variation exists within populations, 2) Organisms compete for limited resources, 3) Organisms produce more offspring than can survive, 4) Genetic traits are passed to offspring, 5) Those organisms with traits most beneficial to survival and reproduction are more likely to survive and reproduce. The document also lists key terms related to biological evolution such as mass extinction, homologous structures, and vestigial structures.
Sealey evolution
This document provides an overview of the key concepts and evidence for the theory of evolution through natural selection. It explains that evolution means change over time as life adapts to survive obstacles. Charles Darwin observed variations between populations and that traits enabling survival and reproduction were selected for. His theory of natural selection and evidence like vestigial organs, homologous and analogous structures, and speciation have supported evolution as the foundation of biology.
K/T Extinction
The document discusses the Cretaceous-Tertiary (K-T) extinction event that occurred 65 million years ago. It notes that this was a mass extinction where over 50% of all species died, including non-flying dinosaurs, many marine invertebrates, flying pterosaurs, mosasaurs, and plesiosaurs. The main proposed cause is the Chicxulub impact crater, evidence for which includes the rare metal iridium and shocked quartz found in K-T boundary layers worldwide. The impact would have released huge amounts of energy, darkened skies for years with dust and ash, and caused global climate changes that disrupted ecosystems.
Earths interior
The document describes the four main layers that make up the Earth - the crust, mantle, outer core, and inner core. The crust is the top-most layer where life exists, ranging from 5-25 miles thick. Below is the mantle, a semi-liquid layer 3000 km wide that causes convection currents moving the continents. Deepest are the solid inner core and surrounding liquid outer core, both composed primarily of iron.
Rocks
The document discusses the three main types of rocks: sedimentary, metamorphic, and igneous. Sedimentary rocks are formed from the compression of sediment layers over time. Metamorphic rocks were once sedimentary or igneous rocks, but were changed by heat and pressure. Igneous rocks form either underground from cooled magma or above ground from volcanic eruptions. Examples of each rock type are also provided.
Geological evolution
Geological evolution refers to gradual changes in the Earth over time, including through plate tectics. Plate tectonics involves large pieces of the Earth's outer layer called plates that move and change position. One aspect is continental drift, where the shifting plates cause continents to gradually change location. Scientists believe the continents were once joined in a supercontinent called Pangaea. Relative dating uses rock layers and fossils to determine the age of rocks, such as the law of superposition that the top layer is youngest and bottom oldest.
The geological time scale
The document discusses the Geological Time Scale which is used to divide Earth's history into eras, periods and epochs based on fossil and rock evidence. It describes the major eras - Precambrian, Paleozoic, Mesozoic and Cenozoic - along with key environmental conditions and lifeforms that existed during each era, noting major extinction events. The timeline shows how life on Earth has evolved and changed dramatically over its approximately 4.5 billion year history.
Earth’s history intro
Earth's history can be determined through relative and absolute dating methods. Relative dating uses the law of superposition to determine the relative age of rocks and fossils by their position in rock layers, with lower layers being older. Absolute dating provides specific numerical ages by using radiometric dating techniques to measure the decay of radioactive elements. Together these methods are used to construct geologic timescales that reveal the order and ages of events in Earth's development.
Continental drift pp
Alfred Wegener proposed the theory of continental drift in 1912, which stated that approximately 250 million years ago, all the continents were joined together in a supercontinent called Pangaea. Over time, the continents gradually drifted apart to their current locations. The key evidence for continental drift included the matching coastline shapes of continents, the presence of matching fossil distributions on different continents, identical rock patterns found across continents, and evidence of past shared climates from fossil evidence.
Fossils power point
Scientists study Earth's past environments and lifeforms by examining fossils. Fossils form when organisms are buried and their remains are replaced with minerals over time. There are different types of fossils including molds, casts, petrified remains, preserved fossils like those trapped in ice or amber, carbonized remains, and trace fossils like footprints. Together, the analysis of these various fossil types provides evidence about ancient organisms, environments, behaviors and evolutionary relationships.
Geo time
This document discusses the history of determining the age of the Earth. It describes how early estimates ranged from thousands of years based on biblical interpretations to hundreds of millions of years based on experiments measuring cooling of materials and sediment accumulation. The development of radiometric dating in the early 1900s allowed for more precise measurements by analyzing the decay of radioactive isotopes. Radiometric dating of the oldest rocks and minerals has provided evidence that the Earth is approximately 4.5 billion years old and the solar system formed around 4.6 billion years ago.
