Kids learn about ocean tides including tidal currents and types of tides. This rising and falling of the sea level is caused by the gravity of the Moon and the Sun.

Tides are easier to see where an ocean meets land along seacoasts and in bays. There are usually two high and two low tides per day at any given place. The times at which they happen, however, change from day to day.

The tide is the regular rise and fall of the oceans. Tides actually occur in all bodies of water but are seen most prominently where the oceans meet the land as well as in bays and harbors. In small, enclosed areas such as lakes and ponds, the rise and fall of the water are slight and usually pass unnoticed. High Tide and Low Tide

The tides are caused by the gravitational pull of both the moon and the sun on the earth’s surface. Because the moon is closer to the earth, its pull is stronger than the sun’s, even though the sun is much larger.

2023年10月16日 · A tide is the periodic rising and falling of Earth's ocean surface caused mainly by the gravitational pull of the Moon acting on the oceans. Tides cause changes in the depth of marine and estuarine (river mouth) waters. Tides also make oscillating currents known as tidal streams (~'rip tides').

2023年10月19日 · The gravitational pull of the moon and the rotational force of the Earth cause tides to rise and fall across the planet. The species living in coastal areas most affected by changing tides have unique ways of surviving.

2023年10月19日 · People can be very active in the low-tide zone. Simple nets, rakes, and traps can catch fish, crabs, mussels, and clams. The regular rise and fall of the ocean ’s waters are known as tides. Along coasts, the water slowly rises …

Tides are the daily or twice daily rise and fall of the oceans. Tides are caused by the gravitational pull of the moon and sun on the ocean. Click to view larger and see the legend. The difference between high tide and low tide is called the tidal range.

2023年9月6日 · A tide is the periodic rising and falling of Earth's ocean surface caused mainly by the gravitational pull of the Moon acting on the oceans. Tides cause changes in the depth of marine and estuarine (river mouth) waters. Tides also make oscillating currents known as tidal streams (~'rip tides').
