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 astronomy, the main sequence is a continuous and distinctive band of stars that appears on plots of stellar color versus brightness. These color-magnitude plots are known as HertzsprungâRussell diagrams after their co-developers, Ejnar Hertzsprung and Henry Norris Russell.fter the hydrogen fuel at the core has been consumed, the star evolves away from the main sequence on the HR diagram. The behavior of a star now depends on its mass, with stars below 0.23 M â becoming white dwarfs directly, whereas stars with up to ten solar masses pass through a red giant stage.
