Final answer:
If Earth had no moon, the tides would primarily be influenced by the sun, leading to smaller and less pronounced tides. There would be two equal high tides and two equal low tides every 24 hours. There would be no spring and neap tides without the moon's gravitational interaction.
Step-by-step explanation:
If Earth had no moon, the tides would be significantly different compared to the current tides we experience. Tides are caused by the gravitational pull of the moon and the sun on the Earth's oceans. The moon's gravitational pull is stronger on the side of the Earth facing the moon, causing a high tide, while the side opposite to the moon experiences a low tide. If there was no moon, the tides would be primarily influenced by the sun. The gravitational force of the sun is about 180 times weaker than the moon's, so the tides would be much smaller and less pronounced. The absence of the moon would result in more consistent tidal patterns throughout the day with two equal high tides and two equal low tides every 24 hours, as the sun's gravitational force remains relatively constant throughout the day. Additionally, without the moon's gravitational interaction, there would be no spring and neap tides, which occur when the gravitational forces of the moon and sun align or oppose each other.
