• New moon and full moon

• Crescent moon and gibbous moon

• Last quarter moon

What are Neap Tides characterized by?

• Higher high tides and lower low tides

• Lower high tides and higher low tides

• Strong tidal currents

• High waves

When do Neap Tides occur?

• During new moon and full moon

• During the first and third quarter moons

• During the crescent moon

• At night

What effect do Spring Tides have on coastal areas?

• They create minimal tidal variation

• They cause higher high tides and lower low tides

• They have no effect

• They only occur in the summer

Which force is stronger in influencing tides on Earth?

• The Sun's gravity

• The Moon's gravity

• Earth's gravity

• Wind force

What is a tidal bulge?

• A large wave

• A bulge of water created by gravitational forces

• A sand dune

• A mountain range underwater

How many high tides occur each day on most coastlines?

• One

• Two

• Three

• Four

What is the main factor causing Neap Tides?

• The alignment of the Sun and Moon with Earth

• The right-angle position of the Sun and Moon with Earth

• Earth's tilt

• Storms at sea

What happens during a full moon in relation to tides?

• Only low tides occur

• Spring Tides occur

• Neap Tides occur

• No tidal changes occur
