conduction
convection
radiation
evaporation
question 6 1 pts
when air near earths surface warms, it rises and cooler air sinks to take its place. this cycle of rising and sinking air is an example of -
radiation
conduction
convection
reflection

Explanation:

• First Question: Conduction is the transfer of heat through direct contact. When you touch a hot metal spoon, heat moves from the spoon (hotter object) to your hand (cooler object) via direct contact, which is conduction. Convection involves heat transfer through the movement of fluids (liquids or gases). Radiation is heat transfer via electromagnetic waves (like the sun's heat reaching Earth). Evaporation is a phase - change process (liquid to gas) and not a heat - transfer mechanism in this context.
• Second Question: Convection is characterized by the cyclic movement of a fluid (in this case, air) where warmer, less - dense air rises and cooler, denser air sinks. Radiation is heat transfer without a medium (e.g., from the sun). Conduction requires direct contact (e.g., heat transfer through a solid). Reflection is a property related to light or waves bouncing off a surface and not a heat - transfer method.

Answer:

• First Question: Conduction
• Second Question: Convection
