Question

which event occurs during high tide?
all of earths ocean levels rise.
the moons orbit is closer to earth.
the gravity of the sun and moon cause the earths crust and water to bulge.
earths crust and water are being pulled in opposite directions by the sun and moon.

Explanation:

• High tide is caused by the gravitational pull of the Sun and Moon. When their gravitational forces combine, they cause the Earth's crust and water to bulge.
• Option 1: Not all of Earth's ocean levels rise uniformly during high tide.
• Option 2: The Moon's orbit being closer to Earth is not the direct cause of high tide in the described sense here.
• Option 4: It's the combined gravitational pull (not pulling in opposite directions in the way described here) that causes the bulge for high tide.

Answer:

The gravity of the Sun and moon cause the Earth's crust and water to bulge.
