1. tsunamis are:

caused by wind and restored by gravity.
shallow water waves caused by earthquakes.
waves that only travel in coastal waters.
caused by hurricanes.
restored by surface tension.

Explanation:

Question 10

To solve this, we analyze each option:

• Speed: Rate of wave movement, not distance between crests/troughs.
• Crest: The peak of a wave, not a distance.
• Amplitude: Maximum displacement from equilibrium, not distance between crests/troughs.
• Period: Time for one wave cycle, not distance.
• Wavelength: Defined as the distance between two consecutive crests or troughs.

Analyzing each option:

• "Caused by wind and restored by gravity": Wind causes wind waves, not tsunamis.
• "Shallow water waves caused by earthquakes": Tsunamis are shallow - water waves (in terms of their behavior relative to ocean depth) and are often caused by earthquakes (seismic activity).
• "Waves that only travel in coastal waters": Tsunamis can travel across entire ocean basins.
• "Caused by hurricanes": Hurricanes cause storm surges, not tsunamis.
• "Restored by surface tension": Surface tension restores capillary waves, not tsunamis.

Answer:

E. wavelength
