Although year-to-year variations arise from thermal energy differences and other contributors such as tectonic uplift, the basic climatological structure of atmospheric circulation on the global scale remains at near-equilibrium conditions, as does the energy cycle through the Earth. Thus, the energy driving convection in the atmosphere was not created in isolation and does not act alone.
Rather, Earth's energy cycle is a connected chain of energy transactions that is continuously running and driving downstream processes. Starting from the conversion of incoming solar flux into surface heat, geothermal energy, tidal energy, etc., each energy-requiring process pushes the next step in the sequence, and convection of air in the atmosphere is one of the links in the connected chain that was driven by previous steps and will drive subsequent steps.
Therefore, convection in the atmosphere is not driven by any immediately identifiable energy source (since all contributing energy also came from elsewhere), but as a step in the flow of energy throughout the Earth connects into an interwoven energy cycle at steady-state conditions that fuels water circulation, material flow, biological processes, so on and so forth.
Similarly, the circulation of ocean water is the sum of contributing variables such as breaking waves, wind, Coriolis force, temperature and salinity differences, and tides caused by the gravitational pull of the Moon and the Sun, all of which are processes driven by other upstream processes. The interconnected energy cycle continues to run at steady-state conditions, with the cause and effects of upstream energy transactions adding up to the circulation process of ocean water.
What else can I help you with?
Heat rising from within earth causes earth's what to move?
Heat rising from within the Earth causes the Earth's tectonic plates to move. The constant rising and sinking of heat are called convection currents.
What causes convection currents it the mantle?
Convection currents in the mantle are mainly caused by the heat generated from the radioactive decay of elements within the Earth's interior. This heat creates temperature differences in the mantle, causing warmer, less dense rock to rise and cooler, denser rock to sink, driving the movement of mantle material in a continuous cycle.
What does the mantle convection cause?
Mantle convection is the slow motion of the Earth's silicate mantle, caused by convection currents that carry heat from the interior to the surface of the Earth. Mantle convection causes the tectonic plates to move around the Earth's surface, causing earthquakes, tsunamis, and volcanic activity.
Which layer does convection occur?
Convection occurs primarily in the Earth's mantle, which is part of the Earth's interior. Heat from the core causes molten rock to rise, cool, and then sink again, creating a continuous cycle of heat transfer known as mantle convection. This process is responsible for driving plate tectonics and shaping the Earth's surface features.
What drives the process of plate teconics?
Mantle convection causes the tectonic plates of the Earth to move slowly. Mantle convection is when heat moves from the mantle to the surface and causes the mantle, and the tectonic plates to move very slowly.
What effect does the heat that causes convection in the earth come from?
Friction
For convection currents in the asthenosphere were does the heat come from?
The heat driving convection currents in the asthenosphere primarily comes from the Earth's internal heat. This heat is generated through the radioactive decay of elements in the Earth's mantle and core. The flow of this heat causes the asthenosphere to partially melt and create convection currents that drive the movement of tectonic plates.
For convection currents in the asthenosphere where does the heat come from?
The heat in the asthenosphere primarily comes from the heat generated by the decay of radioactive isotopes in the mantle and the residual heat from Earth's formation. This heat causes the material in the asthenosphere to become less dense and rise, generating convection currents.
From convection currents in the asthenosphere where does the heat come from?
from the bottom of the earth
What causes convection currents in the earth's mantle and oceans and in the air?
Heat differentials.
Where does the convection occur that causes Earth?
Convection in the Earth occurs in the mantle, the layer of rock beneath the Earth's crust. Heat from the Earth's core causes material in the mantle to heat up, rise towards the surface, cool, and then sink back down in a continuous cycle. This convection movement is responsible for plate tectonics and drives the movement of Earth's lithosphere.
How is the earth heated by convection?
The heating of Earth through convection occurs in the mantle, where the heat from the core causes the molten rock to circulate in convection currents. As the hot material rises and the cooler material sinks, it creates a continuous cycle of heat transfer, which ultimately warms the Earth's surface through the process of convection.
Which layers of the earth does convection occur?
Convection occurs mainly in the mantle, which is the layer beneath the Earth's crust. The heat generated by the core causes convection currents in the mantle, leading to the movement of tectonic plates.
What causes the earth plate to move?
The intense heat in the Earth's core causes molten rock in Earth's mantle to shift. That causes a pattern called a convection cell which forms when material rises, cools, and sinks. When the material sinks, it is warmed and rises again.
What is the heat source that drives convection current Inside earth?
The heat source that drives convection currents inside the Earth is primarily from the decay of radioactive elements within the Earth's core. This heat causes the material in the mantle to become less dense and rise, creating convection currents that drive the movement of tectonic plates.
Heat rising from within earth causes earth's what to move?
Heat rising from within the Earth causes the Earth's tectonic plates to move. The constant rising and sinking of heat are called convection currents.
Which layer of the earth do convection currents occur in?
Convection currents occur in the mantle, which is the middle layer of the Earth. The heat generated from the core causes the molten rock in the mantle to move in a circular pattern, creating convection currents.
