Vor 4 Tagen · An earthquake is an intense shaking of Earth’s surface. The shaking is caused by movements in Earth’s outermost layer. Why Do Earthquakes Happen? Although the Earth looks like a pretty solid place from the surface, it’s actually extremely active just below the surface.
Vor 5 Tagen · Earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another. Learn more about the causes and effects of earthquakes in this article.
- Over the centuries, earthquakes have been responsible for millions of deaths and an incalculable amount of damage to property. Depending on their i...
- Earthquake waves, more commonly known as seismic waves, are vibrations generated by an earthquake and propagated within Earth or along its surface....
- Magnitude is a measure of the amplitude (height) of the seismic waves an earthquake’s source produces as recorded by seismographs. Seismologist Cha...
- Earthquakes can occur anywhere, but they occur mainly along fault lines (planar or curved fractures in the rocks of Earth’s crust), where compressi...
Vor 2 Tagen · An earthquake is a weak to violent shaking of the ground produced by the sudden movement of rock materials below the earth’s surface. The earthquakes originate in tectonic plate boundary.
Vor 2 Tagen · Another theory is that the mantle flows neither in cells nor large plumes but rather as a series of channels just below Earth's crust, which then provide basal friction to the lithosphere. This theory, called "surge tectonics", was popularized during the 1980s and 1990s.
Vor 4 Tagen · Global warming, the phenomenon of increasing average air temperatures near Earth’s surface over the past one to two centuries, happens mostly in the troposphere, the lowest level of the atmosphere, which extends from Earth’s surface up to a height of 6–11 miles.
Vor 2 Tagen · The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere.
Vor 4 Tagen · Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface. Explore Earth!
