which of the following statements regarding earthquake frequency is true?
people can feel an earthquake of any magnitude.
earthquakes are rare and only about a dozen occur every year.
earthquakes of magnitude 5 - 8 are more common that earthquakes of magnitude 2 - 4.
earthquakes are common and occur daily around the globe.

Explanation:

• Earthquakes of magnitude less than 2 are usually not felt by people, so "People can feel an earthquake of any magnitude" is false.
• Earthquakes are not rare. There are many small - magnitude earthquakes occurring constantly. So "Earthquakes are rare and only about a dozen occur every year" is false.
• Small - magnitude earthquakes (magnitude 2 - 4) are more common than medium - to - large - magnitude earthquakes (magnitude 5 - 8). So "Earthquakes of magnitude 5 - 8 are more common that earthquakes of magnitude 2 - 4" is false.
• Earthquakes are common. Due to the movement of tectonic plates, there are earthquakes occurring daily around the globe.

Answer:

Earthquakes are common and occur daily around the globe.
