The sun's heat reaches the Earth through radiation, not conduction or convection. Radiation is the transfer of heat energy in the form of electromagnetic waves, such as light and infrared radiation, which can travel through the vacuum of space to reach us. Conduction and convection require a material medium, which is not present in the vacuum of space.
What else can I help you with?
Why heat cannot reach the earth from the sun by conduction or convection?
Heat from the sun cannot reach the earth through conduction or convection because space is a vacuum and does not contain matter to transfer heat. Heat from the sun reaches the earth through radiation, as electromagnetic waves travel through the vacuum of space.
Why is conduction not responsible for bringing heat to earth?
Conduction is the transfer of heat through direct contact. In the case of the Earth, there is no medium for heat to travel through via conduction since space is a vacuum. Instead, heat from the Sun reaches Earth through radiation, which does not require a medium.
Why does heat move through the earth by conduction rather than convection?
Heat moves through the Earth by conduction because the solid rock and metal layers of the Earth do not have the ability to flow like fluids in convection. The materials in the Earth's interior are rigid, so heat is transferred through them via conduction, where heat energy is transferred from one particle to another.
Why can't heat travel from the sun by convection or conduction?
Because there are no atoms to collide with to transfer the heat energy from the sun, thus, there is no conduction. This is also the same reason that there are no convection currents in space; There are no atoms to collide with to transfer heat. Thus, the only possible way to transfer heat is by radiation.
When the heat source is removed from a fluid conviction currents in the fluid will?
Convective currents in the fluid will gradually decrease and eventually stop as the fluid returns to a more uniform temperature profile. Without the heat source driving the convection, the fluid will gradually reach thermal equilibrium through conduction.

Heat from the sun cannot reach the earth through conduction or convection because space is a vacuum and does not contain matter to transfer heat. Heat from the sun reaches the earth through radiation, as electromagnetic waves travel through the vacuum of space.
What is the surface of earth is much more effectively warmed by this type of heat transfer than the atmosphere?
The surface of the Earth is more effectively warmed by radiation heat transfer than by conduction or convection. This is because radiation from the sun can penetrate the atmosphere and reach the Earth's surface, where it is absorbed and converted into heat. Conduction and convection play a role in redistributing this heat throughout the atmosphere.
Why is conduction not responsible for bringing heat to earth?
Conduction is the transfer of heat through direct contact. In the case of the Earth, there is no medium for heat to travel through via conduction since space is a vacuum. Instead, heat from the Sun reaches Earth through radiation, which does not require a medium.
How is solar heat distributed around earth?
Solar heat is distributed around earth by conduction.
How does heat transfer into a convection cell on earth?
By conduction.
How do you know that heat travels from the sun to the earth by radiation?
It's the only way heat could reach us. It comes via electromagnetic radiation, discovered theoretically by James Clerk Maxwell. It can't come by conduction or convection because space is empty, there is no air there.
What is transferred through the Earth's systems by convection and conduction?
Heat is primarily transferred through the Earth's systems by convection and conduction. Convection involves the movement of heat through the circulation of fluids (such as magma in the Earth's mantle), while conduction involves the transfer of heat through solid materials (such as the rocky layers of the Earth's crust).

How is heat transferred within the earth's atmosphere?
Heat is transferred within the Earth's atmosphere through conduction, convection, and radiation. Conduction occurs through direct contact between molecules, convection involves the movement of air masses due to differences in temperature and pressure, and radiation involves heat being emitted and absorbed by the Earth's surface and atmosphere.
When the heat source is removed from a fluid conviction currents in the fluid will?
Convective currents in the fluid will gradually decrease and eventually stop as the fluid returns to a more uniform temperature profile. Without the heat source driving the convection, the fluid will gradually reach thermal equilibrium through conduction.
What are three ways the earth gets heat?
conduction,convection,radiation
