Describe what causes high tides. What causes spring tides

the Gravitational pull from the moon and the sun create high tides and low tides.  spring tides happen when the sun, Earth, and moon are lined up in a row. the spring tides are the highest tides.

Explanation:

the gravitational pull is so strong and the movement from the water creating energy makes the water, i guess you could say have slightly larger air pockets by expanding, makes the water take up more space...

i hope this helps.
