Question 6 • HOPE Scholars- Science Grade 8

Which force helps keep Earth in orbit?

Answer
A
Earth’s gravity
B
the moon’s inertia
C
the Sun’s gravity
D
the Sun’s inertia

Explanation

The Sun’s gravity pulls Earth toward the Sun and continually bends Earth’s motion into an orbit. Earth’s forward motion keeps it from falling straight into the Sun, while the Sun’s gravity keeps it from traveling off in a straight line. Therefore, the correct choice is the Sun’s gravity.
