High tides are created on Earth when nearby celestial bodies create what change in the oceans?

• Electromagnetic waves reverse the direction of ocean currents.

• Water is warmed by the Sun and then rises to higher levels.

• Radiation striking the water increases salt content.

• Gravity pulls on the water creating bulges on two sides of Earth.

The diagram shows where in the Moon’s orbit it will create different moon phases. Spring tides are the strongest tides and neap tides are the weakest tides. Based on this information and the relative positions of Earth, the Moon and the Sun shown in the diagram, which of the following accurately identifies which moon phases are visible when spring or neap tides occur?

• Spring Tides = First Quarter & Last Quarter Neap Tides = Full Moon & New Moon

• Spring Tides = First Quarter & Full Moon Neap Tides = Last Quarter & New Moon

• Spring Tides = Full Moon & New Moon Neap Tides = First Quarter & Last Quarter

• Spring Tides = Last Quarter & New Moon Neap Tides = First Quarter & Full Moon
