why is the upper part of our ear not as soft as the ear lobe

The upper part of ear not as soft as ear lobe because the upper portion of the ear is made up of cartilage and ear lobe  does not contain any cartilage. Cartilages are parts of the human skeleton system but they are not as hard as bones. These can be easily bent. Cartilage are also present in human's nose.

Here are some information about cartilage:-

Cartilage is a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the elbow, the knee, the ankle, the bronchial tubes and the intervertebral discs.
