Question

5 how deep would you have to drill to reach the center of the earth?
a about 60,000 kilometers
b about 600,000 kilometers
c about 600 kilometers
d about 6,000 kilometers

Explanation:

The distance from Earth's surface to its center is equal to Earth's radius, which is approximately 6,371 kilometers, closest to 6,000 kilometers. The other options are either too large (60,000 and 600,000 km are far beyond Earth's actual size) or too small (600 km only reaches the upper mantle, not the core).

Answer:

D. About 6,000 kilometers
