What else can I help you with?
Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle
What causes volcanoes to erupt under earths surface?
mostly earthquakes or plate tectonic movement.
What are seismic waves and what information information do they give about earthquakes?
Earthquakes are when the seismic plates on the earths crust move after pressure from on another is exceeded, seismic waves are produced after an earthquake, and can turn into a tsunami.
How do geologists use seismic waves to learn about earths?
Seismic waves are used indirectly I have a question for you is this from a chapter 9 science packet section one because I have the same.
Are earthquakes scattered evenly over earths surface?
No, earthquakes are not scattered evenly across the Earth's surface. They tend to be concentrated along tectonic plate boundaries, where plates interact. This results in higher seismic activity in regions like the Pacific Ring of Fire, while other areas may experience significantly fewer or no earthquakes. Factors such as geological structures and historical seismic activity also influence earthquake distribution.
Which type of seismic wave travels on top of Earths surface?
A Surface Wave.
What are the seismic waves that travel along earths surface and produce the most severe ground movements?
What does a seismograph use to record the drums vibrations
What Continuous movement of water from Earths surface to the and back to earths surface?
it is water cycle
What is the point on earths surface where seismic waves are first felt?
This is known as the epicentre.
Seismic shaking is a msasure of?
Seismic waves are the vibrations from earthquakes that travel through the earths surface and is measured bye the shaking you feel.
What is the point on earths surface where the seismic activity is strongest in an earthquake?
The vibrations of a earthquake are strongest where the falt line is.
What kind of waves can travel through earth and along earths surface?
Seismic waves are the types of waves that can travel through the Earth and along its surface. There are two main types of seismic waves: body waves (such as primary and secondary waves) that travel through the Earth's interior, and surface waves (such as Love and Rayleigh waves) that travel along the Earth's surface.
What is horizontal movement of air in realtion to the earths surface?
updraught
Movement along the earths surface caused by an earthquake?
Collide
What causes the shaking of the earths surface caused?
The shaking of the Earth's surface, known as an earthquake, is caused by the release of energy from the Earth's crust due to tectonic plate movement. This movement can occur along fault lines, where stress builds up and is suddenly released, creating seismic waves that result in shaking.
Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle
Do seismic waves travel along earths surface?
Yes, Surface waves, a type of seismic wave, travels along the surface, or appears to, as it loses energy exponentially as it goes away from the surface.
