What planets days last longer than its years?
Venus is the only planet in our solar system where a day (rotation on its axis) is longer than a year (orbit around the sun). A day on Venus lasts around 243 Earth days, while a year (orbital period) is approximately 225 Earth days.
Will gravity last forever?
Gravity is a force that lasts only when the mass/ body that supports it exists. Earth has a magnetic field, as you may know already, and it is caused by the movement of minerals underneath the surface. Once Earth's "lifetime" comes to an end, the earth will erupt. During this time, the Earth's "body" will no longer exist therefore, gravity will disappear.
Where is skylab located in space?
Skylab no longer exists. The last crew left for the final time in 1974. It re-entered the earth's atmosphere 5 years later and burned up.
Why do craters last a million years on the moon?
They last much longer than that. Some of the moon's craters are billions of years old. They last so long because there is nothing to erase them. Earth has wind, water glaciers, volcanoes, and tectonic plates to bury, erode, and erase craters. The moon has none of these processes. Some refer to the moon as geologically dead.
What would happen if we didnt have tornadoes?
Trailer parks would last longer
The last seismic waves to arrive are?
The last seismic waves to arrive during an earthquake are the surface waves, which travel along the Earth's surface and are responsible for the majority of the damage caused by the shaking. These waves move more slowly than the initial primary and secondary waves that travel through the Earth's interior.
What are the differences between seismic waves on Earth and those on the moon?
on July 1969 we set foot on the moon and created seismic waves (moon quakes) that lasted over an hour that would have lasted only 20-30 seconds on earth(earthquakes). So seismic waves last way longer on the Moon then on Earth.
Which seismic wave arrives last at a seismograph station?
The first waves to arrive at a seismograph station are primary waves, or P waves.
What are the seismic waves of the Earth's crust?
Rock under stress breaks at the focus, releasing energy and vibrations called seismic waves, which travel away from the focus, through Earth's interior, and across the surface. The three types of seismic waves are: Primary waves: The first to arrive at seismographs Secondary waves: The second to arrive at seismographs Surface waves: The last and most severe to arrive at seismographs
What is the characteristics of rayleigh waves?
Rayleigh waves are surface seismic waves that travel along the Earth's surface, characterized by a rolling motion that causes both vertical and horizontal ground displacement. They typically have a longer wavelength than other seismic waves, such as P-waves and S-waves, and are responsible for most of the shaking felt during an earthquake. Rayleigh waves tend to cause significant damage due to their ability to propagate over long distances and their complex motion, which can disrupt structures. Their speed is slower than that of P-waves and S-waves, making them the last to arrive at a seismic station.
What seismic wave is found at the surface of the earth?
Rock under stress breaks at the focus, releasing energy and vibrations called seismic waves, which travel away from the focus, through Earth's interior, and across the surface. The three types of seismic waves are: Primary waves: The first to arrive at seismographs Secondary waves: The second to arrive at seismographs Surface waves: The last and most severe to arrive at seismographs
Waves that travel the slowest andare the last to be recorded?
Surface waves, specifically Love waves and Rayleigh waves, travel more slowly than other types of seismic waves such as P-waves and S-waves. They are the last to be recorded on a seismogram and are responsible for the majority of the shaking and damage during an earthquake due to their longer wavelengths.
Are surface waves the first to arrive at a seismic facilty?
No, surface waves are typically the last seismic waves to arrive at a seismic facility. They travel more slowly than body waves (P and S waves) and arrive after the initial shaking caused by the faster body waves.
What waves are detected first because they move so fast.?
There are three types of seismic waves released by an earthquake. Primary waves (P waves) are longitudinal or compressional waves and travel through the Earth's interior. They are first to arrive at a seismic station (velocity 5-8 km/s). Secondary waves (S waves) are a transverse or shear wave and move at a lower speed than that of primary waves (velocity 3-5 km/s). They arrive second at the seismic station. Finally, there are surface waves which as the name suggests travel along the Earth's surface, there are two main types (the Love wave and Rayleigh wave) and these are the slowest types of seismic waves (velocity 2.5 - 4.5 km/s) and hence arrive last at the seismic station.
What is a vibration caused by an earthquake called?
seismic waves
After an earthquake which type of seismic waves reach seismometers last?
A surface wave is the last seismic wave to arrive after an earthquake.
How do earthquakes reveal what the interior of the earth is like?
Earthquakes show us that faults are active and moving. Faults are boundaries between the tectonic plates that make up the Earth's crust. Earthquakes generally happen along faults. The plates move apart or alongside one another releasing energy that causes an earthquake. The energy released causes seismic waves. In fact the core of the earth was discovered with seismic waves. They bend along the interfaces of different materials. There are two different seismic wave types. P waves travel through fluids and solids. S waves travel only through solids. By noticing that the S waves did not go through the center of the earth, geologists came to the conclusion that its center must be a fluid, for S waves cannot pass through fluids. P waves bend in the core because they are slowly passing through a liquid. This has also helped them estimate the size of earth's core by studying the last shadow zone of the S wave.
