However, fossil fuel usage is unsustainable and causes significant environmental damage, such as air and water pollution and the emission of greenhouse gases contributing to climate change. Alternative renewable energy sources need to be adopted to replace fossil fuels and reduce their negative impacts on the planet.

Fossil fuels
Fossil fuels such as coal, oil, and natural gas were formed from the remains of dead plants and animals that lived millions of years ago. Coal is a hard, black rock formed from vegetation that grew in swampy areas 400 million years ago. Oil is formed from the remains of marine organisms and is used as fuel for transportation and manufacturing. Natural gas is composed mainly of methane and is used for heating, cooking, and electricity generation. Fossil fuels are extracted and refined for energy use but their extraction and use also carries environmental risks such as oil spills.
Fossil fuel
Fossil fuels are composed of remains of ancient organisms compressed over millions of years. The three main types are coal, oil, and natural gas. Coal is used for heating homes and industry, while oil is refined and used mainly for transportation fuel and plastics. Natural gas is also used for heating and generating electricity. Fossil fuels are non-renewable and their combustion produces pollution, but they currently supply over 80% of the world's energy needs due to being energy dense and easy to transport.

An oil refinery or petroleum refinery is an industrial plant where crude oil is transformed and refined into more useful products such as gasoline, diesel fuel, jet fuel, naptha, asphalt, heating oil, kerosene, liquefied petroleum gas, and fuel oils.
Oil, coal, natural gas and other fossil fuels are called "fossil" because these fuels are the preserved carbon-hydrogen remnants of ancient life. Coal is formed from plants that decomposed and accumulated in ancient swamps.
EXAMPLES: Fossil Fuels:
Coal: Coal is the primary fuel for the production of electricity and is responsible for about 40% of the electric power supply in the United States.
Oil: Oil is the primary source for the world's transportation.
Natural Gas: About 27% of U.S. energy is fueled by natural gas. Natural gas is the cleanest burning fossil fuel.
CHEMISTRY: fossil fuel combustion.
One molecule of methane, combined with two oxygen molecules, react to form a carbon dioxide molecule, and two water molecules (usually given off as steam or water vapor) releasing energy. See Lecture 3 and figure below.
COAL
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.
NOTE: Geologists classify rocks into three main rock types. Rocks are either a single mineral or a combinations of minerals.
Sedimentary rocks are a type of rock that formed by the accumulation or deposition of small particles (minerals or organic matter) at the Earth’s surface, subsequently followed by their cementation on the floor of oceans or other bodies of water. Examples: sandstone, limestone (see below).
Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs. Its major materials are the minerals calcite (CaCO3).
and aragonite,
which are different crystal forms of calcium carbonate (CaCO3).
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat and pressure, causing profound physical or chemical changes. The precursor may be a sedimentary, igneous, or existing metamorphic rock. Examples: slate, marble.
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite (see above) or dolomite. In Geology, the term marble refers to metamorphosed limestone. The Taj Mahal in the Indian city of Agra is entirely clad in marble.I was amazed to find that the limestone in the Taj Mahal structure is so transparent, the interior of this architectural masterpiece is “illuminated.”

Newton’s third law of motion
Newton's third law of motion states that for every action, there is an equal and opposite reaction. The document provides examples of this law, such as bumper cars pushing against each other with equal forces in opposite directions. It also explains that it can be difficult to identify the action-reaction pair when one object is much more massive than the other and does not noticeably move, such as the Earth when a person walks on it. The document asks the reader to think of additional examples of Newton's third law of motion.
Introduction to electricity
Electricity is caused by the movement of electrons between atoms. Atoms are made up of protons which have a positive charge and electrons which have a negative charge. When atoms gain or lose electrons, they become positively or negatively charged which allows electric forces to act between them. Charged objects can either attract or repel depending on whether they have the same or opposite charges. Materials that allow electrons to move through them easily are conductors, while insulators do not, which is why electrical wires have plastic coatings to prevent electric currents from flowing through the human body.
Refraction and lenses
Refraction occurs when light bends as it passes from one substance to another. Lenses cause light to bend based on their shape - convex lenses are thicker in the center and bend light inward to focus it, while concave lenses are thicker on the sides and bend light outward. Convex lenses form inverted and magnified images when the object is beyond the focal point, and upright images when the object is closer. Concave lenses always form upright and smaller images that do not focus due to the light rays spreading out.
Newton’s second law
Newton's second law states that an object will accelerate in the direction of the net force acting upon it. The acceleration of an object is directly proportional to the net force and inversely proportional to the object's mass. Some examples given are that a kicked ball will accelerate forward in the direction of the kick, and an empty box will accelerate faster across the floor than a box packed with books if both are pushed with the same force due to differences in their masses.
Reflection mirrors
Light rays follow the law of reflection when striking a surface, where the angle of incidence equals the angle of reflection. When light reflects off a smooth, even surface like a mirror (normal reflection), an image can be seen due to the light rays reflecting directly into the eye. In contrast, rough or uneven surfaces cause diffuse reflection, scattering the light rays in many directions so no clear image is formed.
Friction
Friction is an unbalanced force that slows objects down and is present in almost all real-life situations. There are different types of friction including static friction, sliding friction, rolling friction, and air resistance. Static friction prevents an object from moving when a force is applied, sliding friction slows down objects that are sliding against each other, and rolling friction allows wheels to turn forward while pushing back.
Light!
1) The document discusses the properties and behavior of light, including that light carries energy as an electromagnetic wave. It travels in straight lines called rays.
2) When light hits an object, it can be absorbed, reflected, or pass through. Reflection is when light bounces off an object and into our eyes, allowing us to see things.
3) Visible light is a small part of the electromagnetic spectrum. Different colors are wavelengths of light, with blue having a higher frequency than red. The color we see is determined by the wavelengths reflected by an object.
Energy in motion
Kinetic energy is the energy of motion that an object possesses due to its mass and velocity. It can be transferred between objects through momentum or forces. The law of conservation of energy states that energy cannot be created or destroyed, only transferred or changed from one form to another, such as potential energy transforming to kinetic energy. Kinetic energy is calculated as one-half the mass times the velocity squared (KE=1/2mv^2), while potential energy depends on the mass and height of an object above the ground or another reference point and is calculated as mass times the force of gravity times height (PE=mgh).
Momentum and inertia
This document discusses momentum and inertia. It explains that momentum is calculated as mass times velocity, and was defined by Isaac Newton as the key factor for describing motion. The law of conservation of momentum states that the total momentum of a system will remain constant if no outside forces act on it. When objects collide and one slows down, the other gains momentum and speeds up, keeping the total momentum the same. Examples of momentum transfers are described, such as billiard balls colliding in a rack.
How do waves behave
Waves can behave in several ways as they interact with objects and each other. They can reflect off surfaces, refract as they pass between different materials by changing speed and direction, diffract by bending around barriers, and interfere by combining with other waves to form a new wave. Reflection causes echoes, refraction makes underwater objects look closer, diffraction allows sound to travel around corners, and interference is used in things like CDs and ear plugs.

Wave properties
Waves have characteristics that can be observed and measured. The amplitude of a wave measures how far above or below the normal level it rises, and represents how much energy the wave carries. Amplitude is half the distance between the crest and trough of a transverse wave. Wavelength is the distance between two crests or troughs, and determines properties like a light wave's color. Frequency is the number of waves that pass a point in one second, measured in hertz, with higher frequencies associated with shorter wavelengths because more waves can fit in the same space.
Waves!
Waves transfer energy through matter or space without transferring matter. There are two main types of waves: mechanical waves, which require matter to transfer energy, and electromagnetic waves, which do not require matter. Mechanical waves can be transverse, where the matter moves perpendicular to the direction of energy transfer, or compressional, where the matter moves parallel to the direction of energy transfer. Sound waves are an example of compressional mechanical waves that transfer energy through the compression and rarefaction of matter like air molecules.
Velocity and acceleration
This document discusses velocity, acceleration, and how to calculate them. It defines velocity as the rate of change of displacement and acceleration as the rate of change of velocity. It provides examples of positive and negative acceleration, such as speeding up or slowing down. The key formula for calculating acceleration is given as the change in velocity divided by the time taken, usually measured in meters per second squared. Examples are provided to demonstrate calculating average acceleration from changes in velocity over time.
Motion and force
This document discusses motion, speed, and velocity. It defines motion as a change in an object's position over time. Speed is defined as the rate of change in an object's position, usually measured in meters per second. Velocity differs from speed in that it includes both speed and direction of the object's motion. The document provides examples of calculating average speed by dividing total distance traveled by total time, and defines velocity as displacement divided by time.
Introduction to solutions (chapter 5)
This document introduces key concepts about solutions and mixtures. It defines a solution as a homogeneous mixture formed when a solute dissolves evenly throughout a solvent. Water is discussed as a common solvent that can dissolve many substances to form solutions. The reading also distinguishes between heterogeneous mixtures, where substances are not evenly mixed, and homogeneous mixtures or solutions, where the mixing appears uniform. An upcoming student activity is described where groups will create mixtures using water and different substances to observe solubility.
Volcanoes and eruptions
Volcanoes form at plate boundaries or in hotspots in the mantle not associated with plate boundaries. There are three main types of volcanoes: shield volcanoes which have gentle slopes built up from fluid lava flows; cinder cone volcanoes which are steep sided due to explosive eruptions throwing tephra into the air; and composite volcanoes which have layers of both lava and tephra from eruptions that alternate between explosive and nonexplosive. The amount of gas and silica in magma determines the explosiveness of an eruption, with more gas and less silica leading to more violent eruptions as the gas escapes quickly closer to the surface.
Introduction to volcanoes!
Volcanoes form when magma from beneath the Earth's surface is forced up through openings in the crust called vents. They occur at plate boundaries where tectonic plates are moving together or apart, as well as at hot spots where areas of the mantle are unusually hot and melt rock that rises toward the surface. Common examples of active volcanoes include Kilauea volcano in Hawaii and volcanoes in Iceland, Mexico, Ecuador, Indonesia, and Costa Rica.
Behaviour of liquids and gases
The document discusses the behavior of liquids and gases through diffusion and pressure. It defines diffusion as the mixing of particles from an area of high concentration to low concentration. Pressure is defined as force applied over an area, with Pascal's principle stating that applying pressure at any point in a confined substance will cause the pressure to travel unchanged throughout the substance. The document provides examples of how increasing the pressure of a gas by adding more particles to a confined space, such as inflating a balloon.
States of matter
The document discusses the kinetic theory of matter and the states of matter. It explains that the kinetic theory states that particles in matter are in constant, random motion and that the arrangement and movement of atoms determines the state of matter. It then describes the three states of matter - solid, liquid, and gas - and how temperature affects the motion of particles and ability to change states.
