seismic wave are earthquake waves the types are l - waves, p - waves and s- waves they are recorded by seismograph or also called seismograph they form by explosion's, earthquakes and movement (waves) underground.

Rhyolitic magma typically forms beneath continental crust due to high silica content and low temperature. The silica-rich composition leads to viscous magma, which is more common in continental settings compared to oceanic crust where magma tends to be more basaltic and less viscous.

Because he could not explain how the continents moved.

The unit of integrated water vapor is typically expressed in millimeters (mm) or kilograms per square meter (kg/m2). It represents the total amount of water vapor present in a vertical column of air above a specific location.

When all the contents were together there was shallow water in Michigan so the Petoskey Stone was transferred to Michigan and that's how it supports the continental theory.

hope this helps. ;-D

Seismic waves are produced by earthquakes, rather than the cause of them!

The most damaging seismic waves are the surface waves of which there are two types. Love waves and Rayleigh waves.

Scientist rejected Wegners hypothesis of continental drift at first because he did not have enogh evidence to support his theory. He failed to provide a suitable mechanism that could cause the continents to move.

No, at least not in any units that I know of.

Try 25,000 (or 24,900) miles.

A Titanic plate is a collector's item or souvenir plate commemorating the RMS Titanic, a famous ocean liner that sank in 1912 after hitting an iceberg on its maiden voyage. These plates often feature images or information related to the ship and its tragic story.

To reduce the potential damage caused by earthquakes, past methods increased the building rigidity by adding shear walls or braced frames. The "Seismic Base Isolation System" is a flexible approach for isolating the structure from the ground, reducing seismic shock propagation into the structure.

In addition to reducing the chance of structural damage, the "Seismic Base Isolation System" also minimizes secondary damage to equipment inside the building such as computers, precision instruments, medical equipment and communications systems.

Dukono is a volcano located in Indonesia that is part of the Pacific Ring of Fire, a region known for frequent seismic and volcanic activity due to the movement of tectonic plates. The volcano sits on the boundary between the Eurasian Plate and the Pacific Plate, where the Pacific Plate is subducting beneath the Eurasian Plate, leading to the volcanic activity in the region.

The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.

A seismic reading under the ocean helps scientists to map the structure and composition of the Earth's crust beneath the seafloor. By analyzing the data from seismic readings, researchers can better understand tectonic plate movements, seismic activity, and the formation of underwater features like rifts and ridges.

Coal is removed from the earth through a process called mining. There are two main methods of coal mining: surface mining and underground mining. In surface mining, large machines remove the topsoil and rock layers to access the coal deposits, while in underground mining, tunnels are dug deep into the earth to reach the coal seams.

The three landforms that result from volcanic activity are volcanoes, calderas, and lava plateaus. Volcanoes are cone-shaped mountains formed by the accumulation of lava and ash. Calderas are large depressions that form after a volcanic eruption empties the magma chamber beneath a volcano. Lava plateaus are large, flat landforms created by multiple layers of solidified lava flows.

23 hours 56 minutes and 4.1 seconds. This is the siderial rotation period, the amount of time it's takes for the earth to rotate relative to the far away stars. An actaul solar day is exactly 24 hours. The difference between the two is down to the distance that the earth has travelled around the sun in that time.

It would take approximately 22 minutes for the first s-wave to arrive at a seismic station 4000 kilometers away from the epicenter of an earthquake. S-waves travel at an average speed of about 3.5 kilometers per second through the Earth's crust and mantle.

amritsar bears a much cold weather in winters than any other plain city in india due to its proximity to the himalayan glaciers and the conventional winds that pass over it.these winds are responsible for amritsar' temperature sometimes dipping as low as minus 6 degree celsius!

Seismic waves are energy waves produced by an earthquake as it generates stress and releases energy along fault lines. These waves travel through the Earth and can be recorded by seismographs, helping scientists study the size, location, and characteristics of the earthquake. By analyzing seismic waves, geologists can understand the underlying causes of an earthquake and assess potential risks for future seismic activity.

The theory of plate tectonics states that the Earth's outer shell, or crust, is divided into several large pieces known as tectonic plates. These plates float on the semi-fluid asthenosphere beneath them and interact with each other through processes like seafloor spreading, subduction, and continental drift. Movement of these tectonic plates is responsible for various geological phenomena such as earthquakes, volcanic activity, and mountain formation.

WHY is the Earth's axis tilted at 23.5 degrees to the ecliptic? We don't know for sure. All rotational motion is "conserved" when masses converge; for example, the rotation of everything in the solar system (with only a couple of exceptions" is counterclockwise as seen from a point far above the North Pole. All the planets orbit that way, the Sun rotates that way, and all but two of the planets rotate that way. We suspect (but ar not CERTAIN) that this is because this is the direction that the primordial planetary nebula was spinning before it collapsed to form our Sun and the planets.

But collisions can change things, and early in its history, w believe that the Earth was involved in a MASSIVE collision - when a planet possibly as big as Mars collided with the Earth. We believe that the mass ejected from the collision formed the Moon. But it also would have changed the rotational pattern of the infant Earth, and is probably responsible for the spin, and tilted axis, of the planet we live on today.

We're not certain; it was more than 4 billion years ago.

Magma that cools deep below the Earth's crust forms intrusive igneous rocks such as granite, diorite, and gabbro. These rocks have a coarse-grained texture due to the slow cooling process deep underground.

Scientists use seismic gaps by identifying areas along fault lines that have not experienced significant seismic activity in a while. These gaps are thought to be storing up stress that will eventually be released in the form of an earthquake. By monitoring these areas closely, scientists can potentially predict when an earthquake may occur based on the build-up of stress in the seismic gap.

The theory of continental is not accepted as it is been disproved, but it was replaced by the theory plate tectonics. This theory accepted because of may factors including the discovery of mid-ocean ridges, subduction zones, and the tracking of plates via GPS and other means.

A eruption of magma that comes from ice rather than rocks is called a glaciovolcanic eruption. It occurs when magma interacts with ice or snow, causing explosive eruptions due to the rapid vaporization of water. These eruptions can lead to the formation of volcanic landforms like tuyas and subglacial volcanoes.
