C. Each location has two low and two high tides every 25 hours
D. High Tides I. Occur on side of Earth closest to Moon and side opposite the Moon
E. Low Tides I. Occur in areas between the two high tides
F. Spring tides I. Occur when the sun and moon pull on the Earth in the same direction II. During full and new moon phase III. Causes a greater difference between high and low tides
Draw this slide Spring tide New moon Full moon
G. Neap tides I. Occurs when the sun and moon are at right angles to Earth. II. During 1st and 3rd quarter phase III. Least difference between high and low tides.
