What are spring and neap tides?

Spring tides occur when the sun and moon are directly in line with the earth and their gravitational pulls reinforce each other to make the highest tides. Neap tides occur when the sun, earth, and moon form a right angle and the sun's gravitational pull counteracts the moon's pull making a weaker high tide.

What causes tides to occur?

The gravitational pull of the moon
