Ocean Tides

Affected by the gravitational pull of the moon and sun, sea levels rise and fall on a daily basis. Ask questions here about high tide, low tide, spring tide and neap tide.

What is the direction of longshore drift in Swanage bay?

The direction of longshore drift in Swanage Bay is generally from the southwest to the northeast. This means that sediment and sand move along the coastline from the southwest towards the northeast due to the prevailing wind and wave conditions in the area.

What is the basic reason for tornado?

Tornadoes form when warm, moist air collides with cool, dry air, creating instability in the atmosphere. This causes the warm air to rise rapidly and rotate, forming a funnel cloud that can extend to the ground, creating a tornado.

Is the tide closer to you standing on the beach when it is out?

Yes, the tide is closer to you when it is out because the water level decreases during low tide, bringing the shoreline closer to you.

If the tide is on the ebb is it going in or out?

High tide is the tide when the water is highest.

What is post prandial alkaline tide?

Type your answer here... Postprandial Alkaline Tide is the transient rise in the pH of the blood and urine after the gastric parietal cells have been stimulated to secrete hydrochloric acid.(HCL)

What is a tidal sequence?

A tidal sequence refers to the repetitive pattern of rising and falling tides over a specific period of time, usually about 12 hours and 25 minutes. It is influenced by the gravitational pull of the moon and sun on the Earth's oceans.

How many low tides do most coastal areas experience during two days and two nights?

Most coastal areas experience two low tides in a span of two days and two nights. This is due to the cyclical nature of the tides, which typically have two high tides and two low tides each day.

If the moon was gone what will happen to the ocean?

The gravitational pull of the moon directly affects the tides in the ocean. If the moon were suddenly gone, the tides would decrease in intensity and frequency. However, other factors like the sun's gravity would still influence ocean tides to some extent.

What is a tidal chart?

A tidal chart is a graphical representation of the predicted tides for a specific location over a period of time. It typically shows the times and heights of high and low tides throughout the day. Tidal charts are essential for activities such as boating, fishing, and beachcombing.

Why are few producers in intertidal zone?

The intertidal zone is a challenging environment with frequent changes in temperature, salinity, and water levels. This makes it difficult for producers like plants and algae to establish and thrive. Additionally, competition with other organisms and physical stressors like wave action can limit the diversity and abundance of producers in the intertidal zone.

When the Sun and Moon line up their gravitational pull causes what type of tide?

When the moon is full, the earth expierences a spring tide. A spring tide includes High high tides and low, low tides. This is due to the gravitational pull of the sun is cooperating with the moons gravitational pull therefore creating high tides on opposite ends of the earth and the same for the lows.

What are semidiurnal tides?

Semidiurnal tides are tides that have two high tides and two low tides of about the same height each day. This pattern occurs because the Earth experiences two high and two low tidal bulges due to the gravitational forces of the moon and sun.

Do high tides occur six hours apart?

Just slightly over that ... about six hours and 13 minutes ... in most places.

What has the greatest effect on the Earth tides why?

The gravitational pull of the moon has the greatest effect on Earth tides. The moon's gravitational force causes bulges in the Earth's oceans, creating high and low tides as the Earth rotates. Other factors, such as the sun's gravity and the shape of the coastline, also play a role in affecting tides.

When and where did tides first start?

Tides originated billions of years ago due to the gravitational pull exerted by the Moon and, to a lesser extent, the Sun on Earth's oceans. Tides occur in all the world's oceans and are influenced by various factors such as the Moon's orbit, Earth's rotation, and the shape of coastlines and ocean basins.

How many times a day do high tides occur around the world how long is it?

Regarding how many:

There are basically two high tides each day.

Regarding how long:

Doesn't quite work like that. The tides are constantly changing. It's either growing or shrinking. If you measure real closely, it'll only be at its absolute highest for a couple of minutes.

If you're less picky, you'll have a high tide of maybe 2-3 hours when it's importantly higher than average.

Makes the water movement of the tide in a narrow strip of coastal land seem extreme?

The ebb tide makes the water movement of the tide in a narrow strip of coastal land seem extreme.A tidal bore makes the water movement of the tide in a narrow strip or coastal land seem extreme.

Why are red tides called red tides?

Red tides are named for the reddish color they give to the water. This red color is caused by a high concentration of algae that produce pigments, like chlorophyll, that can make the water appear red or brown.

The lines where are the songs of spring Ay where are they occur in?

The line "Ay, where are they" occurs in the poem "To the Skylark" by William Wordsworth. The poet is musing on the absence of the birdsong that typically signals the arrival of spring, emphasizing the desolation of the current season.

If you jumped 3 ft high on earth how high would that be on the moon?

It would still be 3ft

However, if the question is about gravity, then for the same force you would expect to jump 18ft.

How many tides does a coast have?

4 of corse now if u live nr the gulf then its 2

What is it called when the tide is at lowest?

The tides are called neap tides. These occur during the First and Third quarter (in terms of moon phases) and are lower than the tides during New Moon and Full Moon phases.

What causes low tide on a coastline?

Low tide on a coastline is primarily caused by the gravitational pull of the moon and sun on Earth's water. When the moon is directly overhead or on the opposite side of the Earth, it creates a low tide as water is pulled away from the shore. Other factors such as the shape of the coastline, winds, and weather patterns can also influence the timing and extent of low tides.

True or false tides result from the rising and falling of the ocean's surface caused by the gravitational pull of the sun and the moon earth?

True. Tides are caused by the gravitational pull of the moon and the sun on Earth's oceans, which result in the rising and falling of the ocean's surface levels.

The medium-sized tides that occur across the entire Earth's surface during the Quarter Moon phases are called?

The medium-sized tides that occur across the entire Earth's surface during the Quarter Moon phases are called neap tides. These tides happen when the gravitational pull of the sun and moon are perpendicular to each other, resulting in lower high tides and higher low tides.
