- Body Waves – Primary (P) & Secondary (S) Waves.
- Surface Waves – Rayleigh & Love Waves.
What are the 3 Seismic waves and their characteristics?
There are three major kinds of seismic waves:
P, S, and surface waves
. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface. A P wave is a sound wave traveling through rock.
What are P waves and S waves in earthquakes?
In P or compressional waves, the vibration of the rock is in the direction of propagation. P waves travel fastest and are the first to arrive from the earthquake. In S or
shear waves, rock oscillates perpendicular to the direction of wave propagation
.
What are the four types of seismic waves quizlet?
- primary waves. -body wave. -push-pull. -particles move parallel to wave direction. …
- secondary waves. -body waves. -side-to-side (typical wave) -particles move perpendicular to wave direction. …
- surface waves. -particles move through surface in circular motion. -slowest, most destructive. wave travels ON Earth.
What are the main types of seismic waves?
The two main types of waves are
body waves and surface waves
. Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.
What are the 2 main types of body waves?
- P-waves. The first type of body wave is called the primary wave or pressure wave, and is commonly referred to as P-waves. …
- S-waves. The second type of body wave is called the secondary wave, shear wave or shaking wave, and is commonly referred to as S-waves. …
- Wave propagation.
What is the difference between P-waves and S waves and surface waves?
P waves can travel through solids, liquids, and even gases. … Unlike P waves,
S waves can travel only through solid materials
. After both P and S waves have moved through the body of Earth, they are followed by surface waves, which travel along Earth’s surface. Surface waves travel only through solid media.
How fast do P waves travel?
P-waves are the first waves to arrive on a complete record of ground shaking because they travel the fastest (their name derives from this fact – P is an abbreviation for primary, first wave to arrive). They typically travel at speeds
between ~1 and ~14 km/sec.
How do seismic waves move?
Explain that earthquake waves move particles of material in different ways: whereas, compressional waves create a
back and forth motion parallel to the direction
of the waves, shear waves create a back and forth motion perpendicular to the direction of the waves.
Where do seismic waves travel slowest and fastest?
There are two types of body waves:
P-waves travel fastest and through solids, liquids, and gases
; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.
Where are seismic waves most powerful?
Seismic waves can be classified into two basic types: body waves which travel through the Earth and
surface waves
, which travel along the Earth’s surface. Those waves that are the most destructive are the surface waves which generally have the strongest vibration.
What is the relationship between S and P waves?
P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves,
rock oscillates perpendicular to the direction of wave propagation
. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
What do P waves feel like?
The waves also travel through the Earth at different speeds. The fastest wave, called the “P” (primary) wave, arrives first and it usually registers a sharp jolt. … “It
feels more abrupt
, but it attenuates very quickly, so if you are far away you often won’t feel the P wave.”
Which seismic waves travel the fastest quizlet?
primary wave
– a type of seismic wave that compresses and expands the ground. This type of wave moves the fastest and can go through both solids and liquids. You just studied 16 terms!
Which seismic wave does the most damage?
S waves
are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface. The slowest waves, surface waves, arrive last. They travel only along the surface of the Earth. There are two types of surface waves: Love and Rayleigh waves.
Why do ships at sea tend not to notice tsunamis?
Why do ships at sea tend not to notice tsunamis? -Tsunamis in deep water have small wave height and long wavelength. … –
In shallow water, the energy of the tsunami must be contained within a larger water column
. -In shallow water, the energy of the tsunami must be contained within a smaller water column.
