Tides and Their Causes starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Tides and Their Causes.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
Describe how the rotation of the Earth affects the timing of tides.
Describe one way in which tides are important for marine life.
Describe the difference between spring tides and neap tides.
Describe what is meant by the term 'tidal bulge'.
If a coastal city experiences a high tide at 6:00 AM, at approximately what time will the next high tide occur?
If a location experiences a high tide at 3:00 PM, when should the next low tide be expected?
If the gravitational force between the Moon and Earth suddenly increased, what would happen to the tidal range?
If the Moon is directly overhead at a coastal location, what type of tide is most likely occurring?
The time between two consecutive high tides is approximately: (1) 6 hours (2) 12 hours (3) 24 hours (4) 48 hours
Which celestial body has the greatest effect on Earth's tides? (1) The Sun (2) The Moon (3) Mars (4) Jupiter

Which of the following best describes a spring tide? (1) A tide with the least difference between high and low water (2) A tide with the greatest difference between high and low water (3) A tide that occurs only in spring (4) A tide caused by wind
Fill in the blank: The difference in height between consecutive high and low tides is called the _______.
Fill in the blank: The gravitational force that causes tides decreases rapidly with _______.
Fill in the blank: The lowest high tide and the highest low tide occur during _______ tides.
Fill in the blank: The point on Earth where the ocean bulges due to the Moon's gravity is experiencing a _______ tide.
Neap tides occur when the Sun, Earth, and Moon form a right angle. True or False?
True or False: The Sun's gravitational pull on Earth's oceans is stronger than the Moon's.
True or False: The tidal effect is stronger at the equator than at the poles.
True or False: Tides are caused only by the gravitational pull of the Moon.
