MOONQUAKE

What is Moonquake?

Definition

Hello People, Moonquake is similar to an earthquake but it lasts for a long time up to 10 minutes. The causes of earthquake movement in the tectonic plate but on the moon it is totally different mechanisms

Types & Causes

  1. Meteoritic impacts
  2. Thermal quake
  3. Shallow quake

1. Meteoritic impacts

It is caused due to the strike of meteoroids hitting the surface of the moon 

2. Thermal quakes

It is caused by the expansion of frigid crust by the sun's heat at 280degree C for two weeks and cool during lunar nights
It is called deep quakes about 700Km below the surface 

3. Shallow quake

The shallow quakes happen at 20-30Km from the surface 
According to NASA, the cool and rigid body of the moon is the reason for the moon quake 
It lasts for a long time up to 10 min  
"Moon quake set the moon to vibrate like a tuning fork"

it is NASA 'S note on the moon quake  🌑

  • According to the apollo seismic network recorded 28 shallow quakes between 1972-1977 
  • Few quakes are about a magnitude of 5.5 on the Richter scale

WHY ARE AURORA VISIBLE IN NORTH AND SOUTH POLE ONLY ?

Hello People, Aurora is a beautiful phenomenon in nature and in physics, most of them know how aurora appears in short due to the charged particle emitted by the sun in the direction of the earth which in turn is endowed with the magnetic field of its own Now we can see why it is happening when the aurora reaches the earth, they get concentrated near the poles because of the strong axial magnetic field there. In another region of the earth, the magnetic field is weaker and so the aurora does not form although the emission of solar wind particles takes place uniformly Credit: rawpixel
