The guidelines used to determine the relative ages of the rocks and events shown by a geologic cross-section is the Law of Superposition. It is the basic law of geochronology.
A topographic profile is a plot showing the shape of the surface of the ground (so hills, hillocks, dips, valleys and the like). Whereas a geologic cross section shows the order and structure of soils and / or rocks below the ground surface. Geologic sections are typically created by first drawing a topographic profile of the section of interest then adding in the underlying strata. An example of the way they are created is given in the related links.
The four large sections on the geologic time scale are eons, eras, periods, and epochs. Each of these divisions represents a different scale of time with eons being the largest and epochs being the smallest.
To provide accurate answers to the directed reading - 8.1 section on determining relative age, I would need specific questions or prompts from that section. Generally, relative age can be determined through principles such as superposition, where younger layers of rock are deposited on top of older layers, and the principle of original horizontality, which states that layers of sediment are originally deposited horizontally. Other methods include examining fossil succession and cross-cutting relationships. If you have specific questions from that section, please share them for tailored answers.
In the cross section, examine the different layers. The layer at the very bottom will be the oldest, and the one above would be slightly newer, and the one above that even newer, and so on, until the most recent rock layer is found at the top. Therefore, the layer you study will depend on those features. If you know the age of one layer, you will know the relative age of another.
Taken along a line drawn on a map, it is a diagram of the structure and position of the rock layers present beneath the surface along this line. Geologists learn how to construct this 3rd dimensional information from a Geologic map, If you want to know how to get at an ore body hidden underground, you need a Geologist to work out where and how deep to dig. Cross sections will be needed to do this.

The Section 8 Voucher housing program helps low income families to pay their rent. Section 8 will not allow a person to rent to any relative.
Section 8 is a federal program, and the answer, except under specific circumstances where the tenant is disabled and the relative is a caregiver, is no.
