How does Jean M. Auel use imagery in The Clan of the Cave Bear?

Examples of Imagery:

“As Creb looked at the peaceful, trusting face of the strange girl in his lap, he felt a deep love flowering in his soul for her. He couldn’t have loved her more if she were his own.”

“The little girl’s gentle touch struck an inner chord in his lonely old heart.”

“Impetuously, with the uninhibited reactions of a child, she reached out to touch his face, to see if the scar felt different.”
