← ScienceWhich outcome happens because Earth orbits the Sun?
A)Spacetime contracts near Earth slightly✓
B)Earth's mass increases cyclically annually
C)Solar system experiences perihelion precession
D)Rate that cosmic rays decay changes
💡 Explanation
Spacetime distortion near massive objects is described by General relativity, and this curvature induces time dilation. The cyclical motion of Earth towards/away from the Sun changes its relative spacetime curvature each year, because Earth's mass is not actually oscillating but its position varies relative to the sun; therefore, option A is true, rather than the other options.
