What is earth's external heat engine?
The Earth's external heat engine is the Sun. It constantly emits light, heat, and energy which are absorbed by the Earth.
What is the source of the Earth's external heat?
the external heat is the sun
What is earths heat source?
The sun
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.
What is the major heat source of earth's crust?
there are many reasons for heat in earths crust. like the friction between rock masses during movements of earths crust. there may also be heat left over from the original heat of earths interior. but the main reason for heat in earths crust is radioactive elements. they give off energy that can be absorbed as heat. some radioactive elements include uranium, thorium, and a form of potassium.
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?
The Earth's external heat engine is the Sun. It constantly emits light, heat, and energy which are absorbed by the Earth.
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 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 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.
How do you use earths heat?
we used the earths heat for gloderal wornng
What is driven by kinetic energy of the molecules?
'kinetic energy of molecules' is heat; so your answer is any heat engine: for example, a steam locomotive.
What is the source of earth's external heat?
the external heat is the sun
