Question 1 of 27070

When there are small differences between the heights of two successive high tides or two low tides, in a tidal day, the tides are called __________.

🔍 Key Concepts

• Semidiurnal tides – typically have two high and two low tides of nearly equal height each day • Mixed tides – have two highs and two lows with noticeable inequality in height • Relationship between the words "small differences" and how regular/irregular the tide heights are

💭 Think About

• Which tide type is defined as having two highs and two lows that are almost the same height in one tidal day? • Which option describes tides where the two highs and two lows are clearly unequal in height, and does that match "small differences"? • Eliminate the choice that is not normally used as a standard tidal classification in tide tables.

✅ Before You Answer

• Confirm which options are the three standard tidal types used in tide tables: diurnal, semidiurnal, mixed. • Check the formal definition: in which tide type are successive high and low waters nearly equal in height? • Verify that diurnal tides involve only one high and one low water per day, so they cannot have "two successive high tides" in a tidal day.
