If the relative positions of the sun and moon affect the ocean’s tides, why would it be helpful for sailors and other people who work on the ocean to understand patterns in the Earth-sun- moon system?
What is the name of the tide when the sun, moon, and earth are all aligned, causing the greatest pull for highest and lowest tides?
Question 10 options:
Low tide
Spring tide
High tide
Neap tide
Answer:
spring tide
Explanation:
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides — both commonly called spring tide
Answer:
Whenever the earth, moon and sun are aligned, the gravitational pull of the moon is augmented by the gravitational pull of the sun, causing larger than average tidal ranges — meaning especially high high tides and very low low tides. These extreme tides are called “spring tides.”

A submarine fills a special storage area known as a ballast with water in order to increase its density. This allows it to dive deeper in the ocean. When a submarine needs to rise rapidly, compressed air is used to push the water out of the ballast. What effect does replacing the water in the ballast with air have on the submarine?
Answer:
the submarine floats after replacing the water with the compressed air
Answer:
The submarine will rise.
Explanation:
To get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood ports at the bottom of the tank. This increases the vessel's displacement.
