A. They are the most destructive earthquake waves.
D. They can move in a rolling pattern through rock, like an ocean wave.
Explanation:
Surface waves are seismic waves that cause the most destruction during an earthquake.
Rayleigh waves are known to cause rolling pattern of rocks just like an ocean waves.
- Seismic waves are elastic waves that notably transmits energy.
- They usually accompany earthquakes.
- There are two broad categories of these waves.
- Surface and body waves.
- Seismic surface waves are low frequency and long wavelength waves.
- They travel very close to the surface.
- They are made up of Love and Rayleigh waves.
- Love waves travels laterally in a horizontal fashion.
- Rayleigh waves rolls like ocean waves in the ground.
- The bulk of the destruction caused during an earthquakes is due to these waves.
- They are the last waves to arrive a seismic station

<span>Carbon (C) is most likely to form covalent bonds with Beryllium (Be) or Sodium (Na) because they are both metals and covalent bonds are metals that share their valence electrons with the gases / non-metals to get to the stable octet. Krypton is a gas and Selenium is a metalloid</span>
100 centimeters thick
Starting thickness was 50 cm
1 cm every 50 years= 1x50
1x50=50
Old thickness + New thickness= 50 + 50 = 100 cm
