The Morphological Projectile Point Types Defined at Gatecliff Became Temporal

question 41

Multiple Choice

The morphological projectile point types defined at Gatecliff became temporal types when:

• A) surface projectile point finds corresponded to point types found in stratified deposits.
• B) a series of radiocarbon dates determined the geological sequence at Gatecliff, and time ranges could then be assigned to the projectile point types.
• C) dendrochronological dating assigned exact years to projectile point types.
• D) thermoluminescence dated the stratified deposits in which the different projectile points were discovered.

Definitions:

Presbyopia

A condition associated with aging in which the eye's lens loses its ability to focus on close objects, resulting in difficulty with near vision.

A common vision condition also known as nearsightedness, where distant objects appear blurry while close objects can be seen clearly.

Visual Pathway

The route taken by light signals converted into neural signals from the retina through various brain regions, culminating in visual perception in the occipital lobe.

Action Potential

A rapid rise and subsequent fall in voltage or electrical charge across a cellular membrane, primarily found in neurons and muscle cells, facilitating communication and response.
