Question

when an earthquake occurs, energy radiates in all directions from its source. the source is also referred to as the ________
seismic zone
focus
epicenter
inertisl point
question 2 (1 point)
________ have the highest velocities
surface waves
p waves
s waves
refracted s waves

Explanation:

For the first question, the focus is the source of an earthquake where energy radiates. The epicenter is the point on the Earth's surface directly above the focus. A seismic zone is an area prone to earthquakes, and "inertisl point" is not a standard term in earthquake - related vocabulary.
For the second question, P - waves (primary waves) are compressional waves and have the highest velocities among seismic waves. Surface waves have lower velocities than body waves (P and S waves). S - waves (secondary waves) are slower than P - waves, and refracted S - waves still have lower velocities compared to P - waves.

Answer:

1. B. focus
2. B. p waves
