Question

part five: identify the tide
directions: identify the statements below as “high tide” or “low tide”. use the diagram to complete the last two questions.
□ low tide
□ high tide
18)
this occurs two times a day when the ocean water is the highest.
19)
this occurs two times a day when the ocean water is the lowest.
20)
this represents the bigger bulge.
21)
this represents the smaller bulge.

Explanation:

Question 18:

High Tide occurs when ocean water is highest, happening twice daily due to gravitational forces from the Moon (and Sun). So the statement "This occurs two times a day when the ocean water is the highest" matches High Tide.

Low Tide occurs when ocean water is lowest, also happening twice daily as the Earth rotates, and the tidal bulges move. The statement "This occurs two times a day when the ocean water is the lowest" matches Low Tide.

The tidal bulge related to High Tide (when water is highest) is the bigger bulge, as more water is accumulated there due to gravitational pull (from the Moon, mainly, and Sun for spring tides). So "This represents the bigger bulge" matches High Tide's bulge.

Answer:

High Tide
