The Earth's core - volcanic activity.
Humans/civilization/industrialism.
Al Gore used this clip from 'Futurama' in his 'An Inconvenient Truth' documentary; gives a great explanation.
light and heat
Because of the size of the sun, there is not enough chemicals on earth to compare to what the sun holds, besides no one has ever gone to the sun to do research on it.
Early in the morning, the sun's rays are not that direct and the heat thus received is not as much as when in the afternoon when the sun's rays are direct. Besides, the morning air takes time to heat up.
is to hepl people if there is no electricity because the energy of it is come from the heat of the sun
Radiant heat I assume you mean the heat emitted by the Sun rather than the heat of the Sun itself.
Lack of humidity
There is nothing else in the solar system which looks like the sun.
There is heat inside the earth, as evidenced by liquid water below three or four kilometers of ice in Antarctica. Fires, lightning, chemical reactions all generate heat without needing sunlight. The sun's contribution, though, overwhelms everything else, by an enormous margin.
Because the Sun is the only source of energy we have. Everything else like coal, oil, gas, hydroelectric, is or was produced by the action of the Sun's light and heat.
There are other sources of heat in the oceans besides the sun.. Most are underwater magma or gas outlets. However, the majority of heat in the oceans does come from the sun. Heat is necessary for convection to occur. There is a possibility for localized convection due to the alternate heat sources, but most, if not all convection would cease without the sun.

it gives off radiation
yes, as the light travels it brings along heat to all of the planets.
Yes.
The Sun
From the sun's heat, it heat up rivers, ponds and seas.
The main source of heat is from the sun.
