What is low tide?

What is low tide?

• A. The regular rise and fall of the ocean's surface influenced by the moon's gravity pulling on earth
• B. Water bulges toward Moon
• C. The time at which the tide reaches its lowest level
• D. Sun and Moon are aligned; strongest

Answer: (C)

Low tide is the moment in the tidal cycle when the water at the shore is at its lowest level. Tides come from the Moon’s gravity tugging on Earth’s oceans, creating two bulges: one toward the Moon and one on the opposite side. As the Earth rotates, any given coastline moves into and out of these bulges, producing high tide when water is elevated and low tide when it recedes to its minimum. The statement about low tide isn’t just the general rise and fall of the ocean—that describes tides overall. The bulge toward the Moon relates to high tide, not the lowest point. The idea that the Sun and Moon being aligned makes tides strongest refers to spring tides, which affect how big the tides are, not the exact moment of the lowest water.
