If you walk barefoot on hot asphalt, energy is transferred by which process?

• Convection

• Radiation

• Conduction

• Reflection

When energy from the sun reaches the air above land, the air warms and rises. Along a coastline, cooler air above the ocean flows toward the land to replace this rising air.

Which of the following best describe these processes?

• Conduction and convection

• Radiation and convection

• Conduction, convection, and radiation

• Radiation and conduction

Kumar is studying how Earth is warmed by sunlight. The following illustration shows his model of the sun and Earth.

Which process is mostly responsible for warming the soil in Kumar’s model?

• Conduction between the lamp and the soil causes the soil to warm.

• Convection currents between the lamp and the soil cause the soil to warm.

• Expansion of particles in the soil causes the soil to warm.

• Radiation from the lamp reaches the soil and causes the soil to warm.
