Which of the following correctly describes the difference between compact bone and spongy bone?

A Spongy bone is lighter than compact bone

Compact bone is composed of repeating units of osteons and is the strongest form of bone tissue. On the contrary, spongy bone is lighter than compact bone tissue and is always located on the interior of the bone. Rather than osteons, spongy bone is also made of thin columns of trabeculae which cover and protect the bone marrow.
