Question

match each scientific term in the list with its correct definition in the list. drag the correct definition next to each term (4 points)
stellar parallax
heliocentric
geocentric
ellipse
a flattened circle, or oval - shaped orbit, with the sun at one focus
a model of the solar system with the sun at the center
the apparent shift in position of a star as earth moves in its orbit around the sun
a model of the solar system with earth at the center

Explanation:

• Stellar Parallax: The definition "The apparent shift in position of a star as Earth moves in its orbit around the sun" matches, as stellar parallax is about the apparent star position shift due to Earth's orbit.
• Heliocentric: The definition "A model of the solar system with the sun at the center" is correct, as heliocentric means sun - centered.
• Geocentric: The definition "A model of the solar system with Earth at the center" is appropriate, as geocentric means Earth - centered.
• Ellipse: The definition "A flattened circle, or oval - shaped orbit, with the sun at one focus" fits, as an ellipse is the shape of planetary orbits (with the sun at a focus).

Answer:

• Stellar Parallax: The apparent shift in position of a star as Earth moves in its orbit around the sun
• Heliocentric: A model of the solar system with the sun at the center
• Geocentric: A model of the solar system with Earth at the center
• Ellipse: A flattened circle, or oval - shaped orbit, with the sun at one focus
