How are convection currents affected by the rotation of the earth?
If the Earth did not rotate, convection currents would move in one straight path, from the equator to the North Pole and back again. The rotation of the Earth causes this path to be skewed so that currents move in smaller circles between these areas. This is called the Coriolis Effect.
How does convection occur in the earth's mantle?
convection occurs in the asthenosphere, which is located under the lithosphere. the inner core heats the liquid mantle and it circles and produces plate tectonic activity.
What causes water currents?
Surface ocean currents are mainly wind-driven and occur in all of the world's oceans. Examples of large surface currents that move across vast expanses of ocean are the Gulf Stream, the North Atlantic Current, the California Current, the Atlantic South Equatorial Current, and the Westwind Drift. Associated with surface currents are counter-surface and underlying currents. Surface ocean currents are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the Coriolis effect. The Coriolis effect holds that because the Earth is spinning, surface waters move in a clockwise direction in the Northern Hemisphere and in a counterclockwise direction in the Southern Hemisphere. The currents eventually come into contact with the continents which deflect them, creating giant oceanic current circles known as gyres. Vertical and ocean-bottom currents are mainly driven by density differences caused by changes in temperature and salinity. Originating in polar regions, cold, salty waters sink to the ocean bottom and move toward the opposite poles where they again surface. Vertical upwelling currents can also be caused by winds "blowing off" a coastline. The displaced waters are then replaced by underlying bottom waters. Currents are important to marine life as they help to move food and nutrients, making them available for photosynthesis, metabolic requirements and/or consumption.
Where do crop circles appear?
Crop circles usually appear in farms or fields
Imaginary line that circles the middle of the earth?
The imaginary line that circles the middle of the earth is called the equator.

Why does the Earth's crust move on top of the magma when getting heated by the earth's core?
Convection currents move the magma around in circles up and down as it gets cooled and heated. And the plates move on top of them.
Why do large land areas cause surface currents to change direction?
because the surface currents move in huge circles ,they move clockwise in the northern hemisphere
How the convection occur in earth's mantle?
convection occurs in the asthenosphere, which is located under the lithosphere. the inner core heats the liquid mantle and it circles and produces plate tectonic activity.
Why does the ocean not move in circles if the earth is rotating?
The ocean does move in circles. If you look at any map showing ocean currents, you'll see that the majority of them make big, somewhat distorted circles.The continents are in the way, so the ocean currents have a rather complicated circulation pattern (see "Thermohaline Circulation").
What completely circles the globe?
There are many things which completely circle the globe. The first thing that comes to mind is the equator, but the artic and Antarctic circles also circle the globe (as well as every other degree of latitude). The taiga forest circles the globe. The atmosphere circles the globe.

What is the definition of convection zone?
the part of the sun that circles in gas and now pretty cool compared to the core and radiation it is now only 2 million degress kelvin
3 examples of convection?
1. energy is transferred by the mass motion of molecules 2. something goes around in circles 3.pot of water being heated to boil
In Google Plus What is the difference between your circles and extended circles?
If you share with your circles, only your circles can see what you've posted. Extended circles includes people who are in your circles' circles. (Hope that makes sense!)
What circles are not on-deck circles on a baseball field?
fungo circles
What are circles with the same radius?
Circles with the same radius are congruent circles.
