A warm ocean current affecting England's climate?
Currents that originate near the equator are going to be warm water currents, and currents that form near the poles will be cold water currents. It is the temperature of the waters in these currents that influence the climates of the land masses by or around which they flow.
What type of current flows in the opposite direction of wind related currents?
oppositional currents
Why did the ocean-going sailboats depend on ocean currents?
currents provide movement in times of little to no wind
What is the relationship between longshore currents and sandbars?
longshore currents for example ,often deposit sand along shorelines,the sand builds up to form sandbars
What type of currents and tides are in the Indian ocean?
warm
What is the force between two perpendicular current carrying wires?
The magnetic force between currents moving in the oppoiste directions is repulsive.
Why two parallel wires carrying electrical current would either be attracted to one another or repelled by one another depending on what directions the two currents were going?
This is caused by the magnetic fields around the wires that are induced by those currents.
What type of currents are currents that involve warm water flowing in different directions at different speeds close to the top of oceans?
surface currents
Blank currents are currents that involve warm water flowing in different directions at different speeds close to the top of oceans?
SURFACE
What directions do ocean currents move?
currents rise and then go down ,which it in cycle to add on to the above; the currents move clockwise in the northern hemisphere and counter-clockwise in the southern hemisphere
How is the nerve special?
Nerve cells carry impulses in the form of electrical currents, they are insulated by myelin to avoid the electrical current from 'leaking out'.
How is the nerve cell specialized?
Nerve cells carry impulses in the form of electrical currents, they are insulated by myelin to avoid the electrical current from 'leaking out'.
Why doesn't air move straight south or north?
Because the rotation of the earth 'drags' the air currents with it - creating eddys and currents with differing strengths and directions.
What causes ocean currents to move in different directions in different hemispheres?
North and South poles
What happens as these currents move up in opposite directions?
the water or fluid will be moving the opposite direction
How does a continent affect the movement of a surface current?
When surface currents meet continents the current changes directions.
Why is it that 2 parallel wires carrying currents in opposite directions repel each other?
two wires carrying currents in opposite direction repel each other because the magnetic field between the wires is strong than on the sides of the wires.wires will move towards the weaker magnetic field from stronger field
