This document discusses methods that geologists use to determine the age of rocks and develop the geologic timescale. It explains that relative dating uses principles like superposition and cross-cutting relationships to determine the relative order of formations, while absolute dating uses radioactive decay and half-lives to determine precise numerical ages. Examples of radiometric dating techniques are provided, such as carbon-14 dating and potassium-argon dating. The major eras and periods of the geologic timescale are also outlined, from the Precambrian Eon to the current Cenozoic Era.

by the shaking itself or by the ground beneath them settling to a different level than it was before the earthquake (subsidence) or (uplift).
Subsidence is the motion of a surface (usually, the Earth's surface) as it shifts downward relative to a datum such as sea-level.
A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other.
Philippines experience a lot of Earthquakes because it is located in the Circum-Pacific Belt, situated in the Pacific Ring of Fire
Pacific Ring of Fire is term used for VOLCANOES only.

As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2. PLEDGE OF LEARNING
1. I can describe how layers of the
rocks (stratified rocks) are formed;
2. I can describe the different methods
(relative and absolute dating) to
determine the age of stratified
rocks;
3. PLEDGE OF LEARNING
3. I can explain how relative and
absolute dating were used to
determine and identify the
subdivisions of the geologic time
scale;
4. PLEDGE OF LEARNING
4. I can describe how marker fossils (also
known as guide fossils) are used to
define and identify subdivisions of the
geologic time scale; and
5. I can describe how the Earth’s history can
be interpreted from the geologic time
scale.
6. Stratification
• Crustal movement, displacement of
soils, and distortion of terrains lead to
layering of rocks
• Sedimentary rocks form as
sediments are deposited on the
bottom of a body of water
7. Nicholas Steno (1638-1686)
• In late 17th century, he introduced
the principle of geologic timescale
• Each layer of the rock could
represent a “slice” of time.
12. Principle of Superposition
• Rock layer above is younger
than the ones below it. (Oldest
on bottom, youngest on top)
13.
14. Principle of Original Horizontality
• Sedimentary layers are deposited in
approximately horizontal sheets.
• If layers are folded, episode of
deformation must have occurred after
rocks formed. Age of folding is
younger than youngest deformed rock
unit.
15.
16. Principle of Crosscutting Relationships
• Any feature (e.g. fault or intrusion)
that cuts across rocks is younger than
the youngest rock that is cut.
18. Illustration of Relative Age Principles
Superposition
Cross Cutting
RelationsOriginal
Horizontality
19. Absolute dating
• use radiometric dating
techniques to determine how
long ago the rock formed in
the exact number of years
20. • Uses radioactive decay and
the Half-life of certain
elements
• Half-life - time it takes for one-
half of the radioactive material
to decay
21. • Half-Life: the time it takes for 50%
(1/2) of the nuclei in a radioactive
sample to decay to its stable isotope
• Multiply the number of half-lives by
the half-life time to get the age of a
fossil
22. • If the half-life of an isotope is 10,000
years and 3 half live have passed,
what is the age of the fossil?
23. Radiometric dating
Radioactive elements (isotopes) used for dating:
• Carbon (C14) - Halflive: 5730 years
• Potassium (K40) - Halflive: 1.25 billion years
• Uranium (U235) - Halflive: 0.71 billion years
• Thorium (Th 232) - Halflive: 14.1 billion years
• Mainly igneous and metamorphic rocks contain
Potassium, Uranium, Thorium
• C14 method to date charcoal, shells, other organic
materials carbon
