Question

earth is tilted on its axis. when one part of earth is tilted toward the sun, the other part is tilted away from the sun. the part tilted toward the sun receives more light energy.
the model shows earth at one point in its orbit around the sun.
image of earth with suns rays and hemispheres
complete the sentences.
at this point in earths orbit, the dropdown hemisphere is receiving more light energy.
the dropdown hemisphere is heating up more.

Explanation:

From the diagram and text, the part of Earth tilted toward the Sun (where the yellow arrows - sunlight - are hitting) is the Southern Hemisphere (since the sunlight is hitting the southern part of the Earth as per the diagram's orientation, with the Southern Hemisphere more exposed to the Sun's rays). So the hemisphere receiving more light energy (and thus heating up more) is the Southern Hemisphere.

Answer:

Southern (for both the first and second blanks, as the hemisphere receiving more light energy will heat up more, and from the diagram, the Southern Hemisphere is tilted toward the Sun's rays shown by the yellow arrows).
