Question
How does the value of g changes with height and depth from earth's surface? Explain by drawing the graph. Or How does the value of acceleration due to gravity change with height above the Earth's surface and with depth from earth's surface?

Answer
The value of $g$ decreases as we move towards height and depth from the earth's surface. The maximum value of $g$ is at the earth's surface. The value of $g$ is affected by height and depth. As shown in picture below.
