Why was a 7.2 magnitude earthquake with an epicenter in Northern Mexico felt over 100 miles away in the southern part of California?

Select one:

- Waves generated by earthquakes cause the entire planet to shake a little.

- Waves generated by earthquakes cause an increase in sound amplitude.

- Waves generated by earthquakes carry energy through the earth's crust.

- Waves generated by earthquakes carry sound through the earth's mantle.

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?
