Energy in the Earth System

Kumar is studying how Earth is warmed by sunlight. The following illustration shows his model of the sun and Earth.
What reasoning explains the process that 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.

Marcus is giving a presentation on Earth's energy flow at Science Night. His poster includes this model, which shows Earth's crust, mantle and core. Which sentence can he include as a caption that correctly describes how energy flows in this system?

• Energy flows from the cooler rock at Earth's crust toward Earth's core.

• Energy flows from the warmer rock at Earth's crust toward Earth core.

• Energy flows from the warmer rock at Earth's core towards Earth's crust.

• Energy flows from the cooler rock at the Earth's core towards Earth's crust.

Brianna goes for a swim in the ocean. She swims away from shore, and as she begins treading the deeper water, she notices that the water on the surface is much warmer than the water touching her toes. What Earth process explains how the surface water was heated?

• gravity

• convection cells in the ocean

• radiation from the sun

• conduction of heat from Earth's crust
