Introduction Melanoma is a type of skin cancer in humans. It begins from moles (dark spots in the skin) and can spread to other organs in the body (malignant melanoma). Melanoma and other types of skin cancer are linked to sunburn. Sunburn is caused by too much exposure to ultra-violet (UV) light from the sun or other sources such as sun lamps. In Earth’s atmosphere, the gas ozone is known to absorb UV light and prevent most of this light reaching the surface of the Earth.

Task Use information from the resource pages to answer the following questions. 1. Which of the 3 layers in skin is on the outside?

2. Name one structure found in the skin layer called DERMIS.

3. Does ultraviolet have shorter or longer wavelength than visible light? Circle the correct answer) Shorter

Longer

4. In the right-hand column of the table write these types of light in the correct order of wavelength from shortest wavelength to longest wavelength: Blue

Infrared

UV-B

Violet

Yellow

Type of light (Shortest wavelength) 1 2 3 4 (Longest wavelength) 5

5. Deaths from malignant melanoma occur most often in which age group? (Circle the correct answer.) Under 30

30 – 39

40 – 69

Over 70

6. Deaths from malignant melanoma occur most often in which gender/sex? (Circle the correct answer.) Male

Female

7. Melanoma is a serious condition. Describe how the thickness of a melanoma affects the seriousness of the condition.
