Since intraplate earthquakes are not near plate boundaries, give a general idea of what you think might cause them. Do the largest earthquakes cause the most deaths and the most damage to property? California is famous for earthquakes along the San Andreas Fault zone but there is another type of plate boundary where large earthquakes occur.
A pulsar is a neutron star that emits beams of radiation that sweep through Earth's line of sight. Like a black hole, it is an endpoint to stellar evolution. The pulses of high-energy radiation we see from a pulsar are due to a misalignment of the neutron star's rotation axis and its magnetic axis.ike a black hole, it is an endpoint to stellar evolution.

In practice, the term pole star usually refers to Polaris, which is the current northern pole star, also known as the North Star.The south celestial pole lacks a bright star like Polaris to mark its position.he closest bright star to the north celestial pole is Polaris. At magnitude 1.97 (variable), it is the brightest star in the Ursa Minor constellation (at the end of the handle of the Little Dipper asterism).
