- Your thermostat sends a signal to your heating system to provide heat for your home - When your oil burner is engaged, heating oil travels from the tank to the burner by way of a pump - Here the oil becomes a fine mist mixed with air - The fuel/air mixture is then injected into the burner where it is ignited in the combustion chamber - The warm air is disbursed through vents, hot water through baseboards, or by steam radiators - What might be the first step of the process?

Q: - As water expands it puts great pressure on the walls of anything containing it, including any rocks which happen to be surrounding it - The force of the pressure exerted on the rock surrounding it is enough to wedge the walls of the crack farther apart, thus expanding and deepening the crack - Clay expends when wet like ice does - This causes rock to break apart - Some plants like mosses and lichens are capable of growing without soil on bare rock - When they do this their roots penetrate pores and crevices and cause rocks to split apart as the roots force their way down through the rocks - What might be the first step of the process?
A: When water freezes it becomes 10% bigger, or takes up 10% more space

- The rocky area has a higher elevation than the surrounding areas - Water from precipitation falls in the area - The water forms a stream - The stream flows towards lower elevation - The stream becomes a river - The river continues to flow along the same path for a long time - The river erodes the rocky area that it touches - The eroded area cuts deeply into the rock. What might be the first step of the process?
----
