The periodic growth and drop in seawater level is known as:

The correct answer is tide. Key Points

• Tides are the periodic rise and fall of sea water levels caused by the gravitational pull of the moon and the sun.
• The cycle of high tides and low tides occurs twice a day, with a period of about 12 hours and 25 minutes.
• Tides are important for navigation, fishing, and other marine activities.
• They also play a role in shaping coastlines and ecosystems.

Additional Information

• Waves are the movement of energy through the water caused by wind, earthquakes, or other disturbances.
  • They can be large or small and travel long distances.
• Sea currents are the continuous flow of water in the ocean caused by differences in temperature, salinity, and wind patterns.
  • They can be surface currents or deep currents and have a significant impact on climate and marine life.
• A brief influx of water onto ordinarily dry terrain is known as flooding.
  • Rain, snow, storm surges, coastal storms, river overflows, and dam failure can all cause flooding.
  • Floods are not always safe.
