Seismic waves are waves of energy that travel through the Earth's layers, and are a result of an earthquake, explosion, or a volcano that gives out low-frequency acoustic energy. Many other natural and anthropogenic sources create low-amplitude waves commonly referred to as ambient vibrations. Seismic waves are studied by geophysicists called seismologists. Seismic wave fields are recorded by a seismometer, hydrophone (in water), or accelerometer.
The propagation velocity of the waves depends on density and elasticity of the medium. Velocity tends to increase with depth and ranges from approximately 2 to 8km/s in the Earth's crust, up to 13km/s in the deep mantle.
Earthquakes create distinct types of waves with different velocities; when reaching seismic observatories, their different travel times help scientists to locate the source of the hypocenter. In geophysics the refraction or reflection of seismic waves is used for research into the structure of the Earth's interior, and man-made vibrations are often generated to investigate shallow, subsurface structures.
The General Certificate of Secondary Education (GCSE) is an academically rigorous, internationally recognised qualification awarded in a specified subject, generally taken in a number of subjects by pupils in secondary education in England, Wales and Northern Ireland over two years (three years in certain schools). One of the main changes to previous educational qualifications in the United Kingdom was to allow pupils to complete coursework during their two years of study, which was marked by their teachers and contributed to their final examination grade. There has been a move recently from doing coursework and modular examinations for part of the course when pupils would take exams throughout the course to an end of year exam after the two years of study (a 'linear' series). The exams are being revised to make them more difficult such as testing skills from a whole text in English instead of part of a text. Coursework has now been replaced by Controlled Assessments in certain subjects, in which the student completes a number of assessed pieces of work which will ultimately count towards their final examination grade in the specified subject. The Controlled Assessment component of the qualification is usually done under exam style conditions. GCSEs being phased in from 2015 generally have little to no coursework/controlled assessment influence on the final grade.
A wave is a disturbance that propagates through space and time, transferring energy. The original meaning was that of waves on water, or Wind waves. Many other phenomena are defined to be like waves.
Waves is the fifth studio album by the Britishprogressive/experimental rock band Jade Warrior released in 1975 by Island Records. The album, written, recorded and produced by Jon Field and Tony Duhig with guest musicians (Steve Winwood among them) consisted of one single composition which in the pre-CD days had to be divided into two parts to fit A and B sides.
Style and concept
Jade Warrior's second of the four Island albums was dedicated to "the last whale". It had no recurring theme and was marked by a slightly jazzier feel than its predecessor, carrying a listener "through dawn-lit countryside full of birdsong, downriver to the ocean, and out among the great whales". Describing the band's musical vision at the time as "increasingly exotic", AllMusic found the Island albums "dreamlike, pushing a lighter jazz sound to the forefront", featuring "myriad percussive sounds but drum kits were rarely in evidence". "The band liked to create a soothing, ethereal feel, then shatter it with gongs and unexpectedly raucous electric guitar, usually from guest David Duhig, Tony's brother. The albums featured occasional celebrity guests such as Steve Winwood, but Jade Warrior had a style of its own", critic Casey Elston wrote.
What is a Seismic Wave?
What happens if you disturb the water of a calm pond?
Yes exactly!
When you disturb the water, it will continuously produce ripples or waves.
Just like in an earthquake, the sudden movement of the underground rocks produces energy waves that moves the Earth’s surface.
These waves are called Seismic Waves. These waves could travel through and on the surface that cause the shaking and vibrations of the ground.
There are 2 types of Seismic waves: Body waves and Surface Waves.
Basically body waves are waves that travel through the Earth’s inner layer. And while Surface waves are waves that can ONLY travel through the surface layer, making the Body waves travel faster than the surface waves. However, surface waves causes more damage than the body waves.

How Earthquakes Form: Unveiling the Forces Beneath! #meyzileyoutubeshorts
Earthquakes occur when there is a sudden release of energy in the Earth's crust, resulting in seismic waves that shake the ground. This energy release often occurs due to the movement of tectonic plates, which are large pieces of the Earth's lithosphere. When these plates grind against each other, tension builds up until it's released in the form of an earthquake. The epicenter is the point on the Earth's surface directly above where the earthquake originates.

General Certificate of Secondary Education
The General Certificate of Secondary Education (GCSE) is an academic qualification awarded in a specified subject, generally taken in a number of subjects by students aged 14-16 in secondary education in England, Wales and Northern Ireland. It was introduced in 1986 (with the first examinations taking place in 1988) replacing the former O Level / CSE qualifications. As well as amalgamating the two former examination systems, one of the main changes was to allow students to complete Course Work during their two years of study, which was marked by their teachers and contributed to their final examination grade.
The qualification is equivalent to a Level 1 or Level 2 (grade depending) Key Skills Qualification. (In Scotland, the equivalent is the Standard Grade.) Some students may decide to ta...

The General Certificate of Secondary Education (GCSE) is an academic qualification awarded in a specified subject, generally taken in a number of subjects by students aged 14-16 in secondary education in England, Wales and Northern Ireland. It was introduced in 1986 (with the first examinations taking place in 1988) replacing the former O Level / CSE qualifications. As well as amalgamating the two former examination systems, one of the main changes was to allow students to complete Course Work during their two years of study, which was marked by their teachers and contributed to their final examination grade.
The qualification is equivalent to a Level 1 or Level 2 (grade depending) Key Skills Qualification. (In Scotland, the equivalent is the Standard Grade.) Some students may decide to take one or more GCSEs before or after they sit the others, and people may apply for GCSEs at any point either internally through an institution or externally.

Enzymes are biological catalysts that:
A. Increase the activation energy of a reaction
B. Decrease the activation energy of a reaction
C. Do not affect the activation energy of a reaction
D. Provide energy for a reaction
The specific region of an enzyme where the substrate binds is called the:
A. Active site
B. Allosteric site
C. Catalytic site
D. Substrate binding region
The substance upon which an enzyme acts is called the:
A. Catalyst
B. Substrate
C. Product
D. Enzyme-substrate complex
The optimal pH for most human enzymes is around:
A. 2
B. 7
C. 10
D. 14
Enzymes are affected by temperature. As temperature increases, enzyme activity generally:
A. Increases
B. Decreases
C. Remains constant
D. Is unaffected
Enzymes are specialized proteins that act as biological catalysts. They speed up chemical reactions without being consumed in the process. Enzymes have specific shapes that allow them to bind with specific molecules called substrates. This binding creates an enzyme-substrate complex, which lowers the activation energy needed for the reaction to occur. Enzymes play crucial roles in digestion, metabolism, and various cellular processes.

What is a Seismic Wave?
What happens if you disturb the water of a calm pond?
Yes exactly!
When you disturb the water, it will continuously produce ripples or waves.
Just like in an earthquake, the sudden movement of the underground rocks produces energy waves that moves the Earth’s surface.
These waves are called Seismic Waves. These waves could travel through and on the surface that cause the shaking and vibrations of the ground.
There are 2 types of Seismic waves: Body waves and Surface Waves.
Basically body waves are waves that travel through the Earth’s inner layer. And while Surface waves are waves that can ONLY travel through the surface layer, making the Body waves travel faster than the surface waves. However, surface waves causes more damage than the body waves.
Now there are 2 types of body waves.
The Primary Waves and the Secondary Waves.

Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. ... Earthquakes radiate seismic energy as both body and surface waves. Body Waves. Traveling through the interior of the earth, body waves arrive before the surface waves emitted by an earthquake.

When an earthquake happens energy spreads outwards in all directions in waves, like a ripple spreading across the surface of a pond. There are 2 main types of earthquake (seismic) waves, compressional P waves and transverse S waves. This video shows P and S waves moving down a slinky.
Earthquakes occur when there is a sudden release of energy in the Earth's crust, resulting in seismic waves that shake the ground. This energy release often occurs due to the movement of tectonic plates, which are large pieces of the Earth's lithosphere. When these plates grind against each other, tension builds up until it's released in the form of an earthquake. The epicenter is the point on the Earth's surface directly above where the earthquake originates. Understanding the complex geological processes involved in earthquake formation helps us prepare for and mitigate their impact.
Seismic waves are waves of energy that travel through the Earth's layers, and are a result of an earthquake, explosion, or a volcano that gives out low-frequency acoustic energy. Many other natural and anthropogenic sources create low-amplitude waves commonly referred to as ambient vibrations. Seismic waves are studied by geophysicists called seismologists. Seismic wave fields are recorded by a seismometer, hydrophone (in water), or accelerometer.
The propagation velocity of the waves depends on density and elasticity of the medium. Velocity tends to increase with depth and ranges from approximately 2 to 8km/s in the Earth's crust, up to 13km/s in the deep mantle.
Earthquakes create distinct types of waves with different velocities; when reaching seismic observatories, their different travel times help scientists to locate the source of the hypocenter. In geophysics the refraction or reflection of seismic waves is used for research into the structure of the Earth's interior, and man-made vibrations are often generated to investigate shallow, subsurface structures.
