How is a earthquake formed facts for kids?
Most earthquakes are caused by changes in the Earth’s outermost shell, or crust. The crust is made up of about a dozen rock masses called plates that are constantly moving. In different places they move apart, collide, or slide past each other. Over time this movement causes great pressure to build up.
What are 4 facts about earthquakes?
Fun Facts about Earthquakes The largest in the US was a 9.2 magnitude in Alaska in 1964. They can cause huge waves in the ocean called tsunamis. Movement of tectonic plates has formed large mountain ranges like the Himalayas and the Andes. Earthquakes can happen in any kind of weather.
What cause an earthquake?
The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel.
What is a interesting fact about earthquakes?
Fun Facts about Earthquakes They can cause huge waves in the ocean called tsunamis. Movement of tectonic plates has formed large mountain ranges like the Himalayas and the Andes. Earthquakes can happen in any kind of weather. Alaska is the most seismically active state and has more large earthquakes than California.
What are 3 causes earthquakes?
These plates move towards each other (a convergent boundary), apart (a divergent boundary) or past each other (a transform boundary). Earthquakes are caused by a sudden release of stress along faults in the earth’s crust.
How do earthquakes start?
Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake.
