Understanding Earth and Space Systems, Heat in the Environment

• 3.1 use the particle theory to compare how heat affects the motion of particles in a solid, a liquid, and a gas. ▹
• 3.2 identify ways in which heat is produced (e.g., burning fossil and renewable fuels, electrical resistance, physical activity). ▹
• 3.3 use the particle theory to explain the effects of heat on volume in solids, liquids, and gases. ▹
• 3.4 explain how heat is transmitted through conduction (e.g., the transmission of heat from a stove burner to a pot and from the pot to the pot handle), and describe natural processes that are affected by conduction (e.g., the formation of igneous and metamorphic rocks and diamonds. ▹
• 3.5 explain how heat is transmitted through convection, and describe natural processes that depend on convection (e.g., thunderstorms, land and sea breezes). ▹
• 3.7 describe the role of radiation in heating and cooling the earth, and explain how greenhouse gases affect the transmission of radiated heat through the atmosphere. ▹
• 3.8 identify common sources of greenhouse gases, and describe ways of reducing emissions of these gases. ▹
