D. Ocean currents.
ConvectionHeat energy is transferred primarily by air movements, storms, and ocean currents. Since the earth is heated unevenly, the energy is redistributed. Air movements, otherwise called wind, are one important mechanism. Storms, which contain water vapor and water, also transfer heat. When water turns to water vapor it absorbs heat and when water vapor condenses to water, heat is released. Therefore, storms are important movers of heat. Ocean currents also transfer heat as cold currents move to warmer areas and warm currents move to colder areas.air movements, storms, and ocean currents
The movement of energy from a warmer object to a cooler object is called convection currents
energy is transferred through moving currents of warmer air or liquid
Conduction Energy ;p
convection
Examples of direct heating methods are fireplaces, cast-iron stoves, and modern space heaters fueled by gas or electricity. This is known as direct heating because the conversion of energy into heat takes place at the site to be heated
the primary source of ocean currents is the sun but other direct energy sources are1. global wind patternsa. trade windsb. the westerly winds*wind is the cause of surface currents in the oceans.
Ocean currents at the SURFACE -- their primary cause is SOLAR ENERGY. Due to solar energy, much of the wind pattern originates and this wind pattern in turn causes ocean currents on the surface.
Yes, fossil fuels are used for direct heating.
the form of energy would be heat. convection currents are caused by uneven heating of air or fluid. The warmer fluid is more boyant than the cooler fluid, so it floats to the top, and creates a "convection current"
Yes. One of the factors behind the wind is differential heating of the earth's surface, which results in convection currents in the atmosphere.
For the most part solar energy refers to solar panels that collect the suns energy and immediately turns it into electrical energy. Once you have electrical energy you can easily connect an electric motor to it. Electric motors are the primary way that electrical energy is transformed into mechanical energy. ---- Directly: radiometers turn with direct sunlight, solar contribution to tides (not really solar energy per se) Indirectly: # solar heating creates thermal currents ("thermals") in air (wind) and water (ocean currents) # solar heating evaporates water, some of which falls as rain on higher elevations, making moving rivers of water # photovoltaic cells absorb light, make electricity, and some the electricity is used to run motors or solenoids
Vertical convection in both the ocean and atmosphere is caused by uneven HEATing.The source of energy for convection in the ocean and atmosphere is heating from the sun.

The side of the Earth facing the Sun has its surface, atmosphere and oceans heated but the energy form the Sun. This then starts convection currents in the atmosphere and oceans as the area of maximum heating (near the equator) tries to distribute the heat to the area of least heating (the poles). The convection currents are moderated by the Earth's rotation due to the Coriolis effect.
The sun provides the thermal energy for currents to be formed.
The kettle will be less efficient because it won't be benefitting from the effects of convection currents. It will use considerably more energy.
