What is earth's external heat engine?
Earth's external heat engine is the planet's climate system, driven primarily by solar energy. The sun's rays heat the Earth's surface, causing air and water to move around in the atmosphere and oceans, creating weather patterns and climate variability. This heat engine plays a crucial role in regulating the planet's temperature and supporting life.
Earths primary external energy source is what?
The Sun is Earth's primary external energy source. Solar radiation emitted by the Sun provides heat and light energy to sustain life on Earth through a process called photosynthesis.
Current in earths mantle that transfers heat in earths interior?
The main mechanism for heat transfer in Earth's mantle is through convection currents. These currents are driven by the heat generated by the decay of radioactive elements in the mantle, causing hot material to rise and cooler material to sink. This convective motion helps drive the motion of tectonic plates and is a key process in the Earth's heat budget.
Plate tectonics is a result of earths internal heat engine powered by?
Plate tectonics results from the convection of the Earth's mantle below. Convection is driven by heat from the Earth's core. The hot core creates a temperature gradient in the mantle that results in convention. In the case of Earth the source of thermal energy comes from two sources: a) primordial heat left over from the Earth's formation b) radioactive decay of certain isotopes of certain elements. In the case of Earth the most important isotope is potassium-40. Thus the heat in the Earth's core is ultimately the power behind a vast heat engine that moves tectonic plates.
How can deep density driven currents affect earths climate?
Deep density driven currents, such as the thermohaline circulation, play a crucial role in regulating Earth's climate by transporting heat and nutrients around the globe. Disruption of these currents can impact regional climate patterns, leading to changes in temperature and precipitation. For example, a weakening of the thermohaline circulation could result in cooler temperatures in certain regions as heat is not distributed as efficiently.
What are earths two heat engines?
the sun is the external heat engine and the core of the planet is it's internal heating engine.
What is earth's external heat engine?

This heat engine plays a crucial role in regulating the planet's temperature and supporting life.
Has a heat source located outside the engine?
External combustion engine is the answer you're looking for.
What are the two types of heat engines?
internal and external combustion engine
what is a heater an internal combustion engine or a external combustion engine?
A heater can be either an internal combustion engine or an external combustion engine, depending on its design and operation. Internal combustion engines generate heat through the combustion of fuel within the engine itself, while external combustion engines produce heat by burning fuel outside the engine to heat a working fluid. Common examples of heaters include furnaces (external combustion) and car engines (internal combustion). The specific classification depends on how and where the combustion occurs in relation to the heat-producing mechanism.
What if ocean currents stop?
Ocean currents cannot simply stop. They are driven mainly by weather systems, heat and the earths rotation
What are examples of heat engines?
internal and external combustion engine
Is the furnace an internal or external combustion engine?
An ordinary furnace is not an engine at all, because it does not directly cause mechanical motion. The heat or expanding gases released in a furnace can be used to drive an engine, but that is a separate component from the furnace. If a furnace is used in this manner, the engine is an external combustion engine.
Is a steam engine an example of an internal combustion engine?
No, the steam engine is an external combustion engine because the steam is heated by heat generated by combustion outside externally through heat transfer. A spark ignition engine is an example of an internal combustion engine.
How do you use earths heat?
we used the earths heat for gloderal wornng
How are heat engines classified?
heat engines are classified on the location of the combustion chamber , if it is outside the whole set up then it is external heat engine and vice versa.
Is furnace an internal or external combustion engine?
An ordinary furnace is not an engine at all, because it does not directly cause mechanical motion. The heat or expanding gases released in a furnace can be used to drive an engine, but that is a separate component from the furnace. If a furnace is used in this manner, the engine is an external combustion engine.
