What is rearrangement of electrons on an uncharged object without direct contact with a charged object?
This phenomenon is known as electrostatic induction.
Does conduction require direct contact?
convection requires a medium to travel. In space there is no air but, a vacuum. Therefore direct heat from the sun is radiation as it does not require a medium to travel.
What is the difference between conduction and radiation?
radiation-energy transferred by waves or rays conduction-transfer of energy that occurs when molecules bump into each other (direct contact)
What type of transfer of energy can take place with little or no matter present?
Some forces, such as gravity or the electrostatic force, can act without direct contact. If a force is applied over a certain distance (such as, when an object falls), work is done, i.e., energy is transferred. Ah, but what is direct contact? One electrostatic field pushing against another? If I touch something, it is the electrostatic fields pushing against each other. There is no direct contact!
What energy is transmitted by direct contact or touch?
We apply the term conduction to the transfer of thermal energy through direct contact. The other two mechanisms that transfer thermal energy are radiation and convection.
What 4 ways transfer of heat energy?

Does radiation requires direct contact?
Yes it does require direct contact with the radiation in order to cause short term and likely long term negative effects to oneself but it is not necessary to be in direct contact with the radio active material itself. The radiation itself is the danger, although the closer you are to the source which is producing the radiation the worse the effects will be because the radiation will be stronger the closer you get to the source which is creating and or supplying the radio activity. So holding or touching the radio active material directly would be the worse case scenario and approaching this material in a measure of some sort would increase the damage to oneself exponentially.

How is heat energy transferd?
Heat is transfered through conduction, direct contact, convection, movement through liquids and gases, and radiation.
ice melting on a hot plate ... Convention, conduction or radiation?
The process of ice melting on a hot plate involves both conduction and radiation. Conduction: Initially, when the ice comes into direct contact with the hot plate, heat is transferred from the hot plate to the ice through conduction. Conduction is the transfer of heat through direct contact between two materials with different temperatures. Radiation: As the ice begins to melt and water droplets form, there may be some heat transfer through radiation. Radiation is the transfer of heat through electromagnetic waves, such as infrared radiation. The hot plate emits infrared radiation, which can be absorbed by the ice and water molecules, contributing to the melting process. So, in summary, conduction is the primary mechanism of heat transfer when the ice is in direct contact with the hot plate, while radiation plays a secondary role as the ice melts and water is present.
How does radiation and conduction work?
Conduction: Heat transfer by direct contact, such as from an electric coil on a stove to the pot. Convection: Heat transfer though the air, such as in an oven. Radiation: Heat transfer via waves, such as from the Sun to Earth.

What is the transfer of energy as heat between objects that are in direct contact called?
That sounds like a definition of "conduction" - as opposed to convection or radiation, which are other modes of heat transfer.
