The strongest of Earthquakes we have ever heard happen to fade away in lesser than 2 minutes. Just imagine what will happen if they keep on and on for 10 minutes? It surely sounds very deadly. Moonquakes keep going for almost 10 minutes. Some Researchers have termed Moon as a Ringing Bell.
The Learning BRUSH will help u explore the very interesting Fact which makes the Moonquakes keep going and Moon termed a Ringing Bell !
Unlike Earthquakes which usually die out in few tens of seconds, Moonquakes can keep going for almost 10 minutes.
Earthquakes on Earth: Earth is weathered by wind and water and also altered by geological forces. This makes the rock soft, when energy passes across such a compressible structure, it acts as a foam and absorbs the vibrations. Even the biggest Earthquakes stop shaking in less than two minutes.
Moonquakes on Moon: Moon is dry, cool, and mostly rigid, like a chunk of stone or iron. The lack of weathering and geological alterations makes the rock very hard. The seismic vibrations make the Moon ring like a bell, so even if Moonquake isn’t that intense, it just keeps going on and on. The vibrations from the Moonquake can keep bouncing back and forth inside the Moon for a long time before finally dying out.
Activity for kids: Make a crafty Moon and attach a bell.Now tell that Moon is termed as a Ringing Bell !
