Q:You are presented with the question "Glaciers melt via" and the following answer choices: - vaporization - thermal conduction - Water expanding - colder temperatures - mountain sources - internal combustion - decreased wind - Physical weathering Now knowing that when a cooler object touches a warmer object , thermal conduction occurs and when the glacier moves into warmer areas the ice melts and sediments are deposited, choose the best answer.
A:
thermal conduction
