People sitting around a campfire are able to feel the heat from the fire. How are the people able to feel the heat from the fire without touching the fire?

• The heat from the fire travels through the ground and heats the ground around the people.

• The heat from the fire is conducted through air molecules to the people.

• The heat from the fire rises in the air and then settles around the people.

• The heat from the fire radiates from the fire to the people.
