Почему Земля не может получить от Солнца тепло через теплопроводность или конвекцию?

This can be translated to:

Why the Earth can not receive the heat of the Sun by conduction or convection?

Ok, first:

Conduction is the transimision of heat by direct contact of two objects, the Earth and the Sun are not touching eachother, so there can not be conduction happening.

Convection is the heat transfer due to the bulk movement of particles or molecules within fluids such as gases and liquids, between the Earth and the Sun we have vacuum, so we can not have convection.
