The combination of absolute and relative dating allows scientists to determine the ages of rocks and fossils. Absolute dating provides evidence that helps us estimate the ages of Earth. How can scientists find the absolute age of igneous rocks?

Answers

Answer 1

Answer:

By radiometric dating

Explanation:

The relative age of a rock sample is determined by comparing a  (or the fossils it contains) to other layers. Relative age of a rock sample can be determined by looking at the position of various rock layers.

Absolute age of a rock sample is the numerical.  Absolute age can be determined by using radiometric dating.

According to Oxford dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."

Answer:

Why is healthy skin important? Healthy skin is important because it is your first line of defense against bacteria and other pollutants in the environment. Healthy skin is more resilient when faced with external stresses, serves as an important sensory organ and helps to regulate our body temperature.

The outermost layer of skin, called the epidermis, produces a thin barrier layer called the stratum corneum. This layer varies throughout the body in its structure, thickness, composition and functional properties. For example, the skin on your palms and soles is thicker than on your face.

Skin changes such as wrinkling are one of the physical alterations most readily associated with aging. It may surprise you that the outer layer of the skin, the stratum corneum, changes very little as we age. The main changes occur at a deeper level. Collagen, a basic chemical building block of skin and connective tissue, decreases with age.
