Tides

What causes tides?

• The rotation of the Earth on its axis

• The gravitational interaction between Earth, the moon, and the sun

• The wind patterns across the oceans

• The temperature changes in the ocean water

Which celestial body has the greatest effect on Earth's tides?

• The Sun

• The Moon

• Jupiter

• Venus

What factors can influence tidal patterns?

• The shape of the coastline, the depth of the water, and the alignment of the moon and sun.

• The temperature of the water, the presence of marine life, and the wind speed.

• The amount of rainfall, the type of fish in the area, and the local population density.

• The gravitational pull of nearby planets, the time of year, and the salinity of the water.

What is the effect of the sun on tides?

• The sun has no effect on tides.

• The sun affects tides more than the moon.

• The sun affects tides, but its effect is less than that of the moon due to its greater distance from Earth.

What is the difference between high tide and low tide?

What is tidal range?

• The distance between the shore and the ocean floor.

• The difference in height between high tide and low tide.

• The speed at which tides flow in and out.
