A crayon placed on a dark driveway in bright sunlight melted into a colorful puddle. What caused the crayon to melt?

• Solar radiation heated the driveway and then thermal energy transferred to the crayon by conduction.

• Solar radiation heated the driveway and then thermal energy transferred to the crayon by radiation.

• Solar convection heated the driveway and then thermal energy transferred to the crayon by radiation.

• Solar convection heated the driveway and then thermal energy transferred to the crayon by conduction.

What causes your skin to feel warm when it is in the sun on a summer day?

• Particles in the atmosphere reflect energy from the sun downward.
• Hot particles from the sun still carry some heat when they reach your skin.
• The solar wind carries heated air from the sun's atmosphere to earth's surface.
• The sun radiates energy that passes through space and the atmosphere to your skin.

The baby chickens are kept warm from the heat lamps demonstrates which type of heat transfer?

• conduction
• convection
• radiation

What causes the circulation of air in the atmosphere?

• Air in the atmosphere is heated by the sun and sinks to the ground.
• The ground is heated by the sun and then heats the air, causing the air to rise.
• Air loses heat to the ground and then rises upward to obtain more energy.
• The sun heats the clouds which forces the cooler air to move away and sink.
