Question

heena is studying the night sky for her science class. she is making observations and recording them in her science journal. she makes observations through the month of april. every night she makes five hourly observations and records her data. she draws the star patterns that she sees each hour for five hours each night. what does heena most likely observe about the star pattern leo?
a the pattern of leo stays in the same part of the sky.
b the pattern of leo appears to move across the sky.
c the stars in leo change positions within the pattern.
d leo changes its shape and forms a new pattern.

Explanation:

The Earth rotates on its axis, causing star patterns (constellations like Leo) to appear to move across the sky over hours. The stars within a constellation don't change positions relative to each other quickly (ruling out c and d), and Leo won't stay in the same part (ruling out a) due to Earth's rotation. So the pattern of Leo appears to move across the sky.

Answer:

b. The pattern of Leo appears to move across the sky.
