Is there a difference between tides and currents?

Question

Is there a difference between tides and currents? if so what? Reason: when crabbing is it affected by tides,currents, time of day etc?

Answer 1

The tide is the cyclic rising and falling of Earth's ocean surface caused by the tidal forces of the Moon and the Sun acting on the Earth. Tides cause changes in the depth of the sea, and also produce oscillating currents known as tidal streams, making prediction of tides important for coastal navigation.

An ocean current is any more or less permanent or continuous, directed movement of ocean water that flows in one of the Earth's oceans.

So yes, tide is the rise and fall of the ocean and current is the direction or movement. I would think that both would affect crabbing to some extent.

Answer 2

Ocean currents are a non-end directed flow of ocean water able to vacationing hundreds of kilometers. floor currents circulate water on the outdoors of the sea, at the same time as submarine river currents flow deep decrease than. Ocean currents can heavily impact the climate of coastal factors. The Gulf flow, case in point, makes northwest Europe the main temperate of any region at that variety. The California contemporary in the Hawaiian Islands ends up in a climate plenty cooler than different tropical latitudes. El Niño is a phenomenon the place an ocean contemporary is reversed ensuing in devastating climate variations from the west coast of South u . s . all the thank you to Australia. Ocean currents additionally impact the life cycles of specific marine creatures, such as eels, which relocate hundreds of kilometers to spawn in step with ocean currents. the sea’s floor rises and falls predictably using variations in gravitational forces originating from the Moon and the sunlight. those variations in ocean floor point are consumer-friendly as tides and are data of the impact celestial bodies have on our planet. devoid of those exterior forces, the sea’s floor might basically exist as a geopotential floor or geoid, the place the water is pulled by way of gravity devoid of currents or tides. The stable gravitational fields of the Moon and the sunlight effect in important changing gravitational fields inflicting tides to upward thrust and fall. because of the fact the sunlight is farther away than the Moon, the sunlight's pull on the tides is approximately 40% as stable because of the fact the Moon's. the two gravitational and tidal forces weaken as distance will boost. Gravitational forces are inverse to the sq. of the gap and tidal forces are inverse to the cube of the gap.

Answer 3

yes
