Question

which of the following is an example of radiation? placing an ice cube in your hand earth receiving heat from the sun the movement of the mantle inside earth

Explanation:

• Placing an ice cube in your hand: This is an example of conduction. Conduction is the transfer of heat through direct contact between materials. In this case, heat is transferred from your hand (warmer object) to the ice cube (cooler object) through direct contact.
• Earth receiving heat from the Sun: This is an example of radiation. Radiation is the transfer of heat in the form of electromagnetic waves (such as infrared waves). The Sun emits energy in the form of electromagnetic radiation, and this energy travels through the vacuum of space to reach the Earth.
• The movement of the mantle inside Earth: This is an example of convection. Convection is the transfer of heat through the movement of fluids (liquids or gases). In the Earth's mantle, hot, less - dense material rises, and cooler, more - dense material sinks, creating a convective current.

Answer:

Earth receiving heat from the Sun
