Journal 3 The cover of the journal replica. The replica of journal 3 included in the DVD contains many pages taken from the journal in the show, including Floating Eyeballs , Gnomes , and The Undead. Each of these pages contains information about said creature or supernatural occurrence. Also, hidden within the book are transparent symbols which can only be seen when reflected by light. The gnomes page is a replica of the page seen in episode 1, not the version edited by Dipper. The cover of Journal 3 has a lot less damage than in the series. The “W,H,A,T” letters that are usually situated around the question mark on the shack’s roof are not there.

Filed under Pagadian City The Philippines, being a country archipelago of islands and seas, have naturally wonderful beaches, some of which are famous the world over. Beaches like Puerto Galera, Boracay, and the various beaches in Cebu rake in tourists from around the world all year round because of their pristine and cool blue waters and fine, white-sand shores.

However, if one will just look around more, they will find that there are other less-known but equally beautiful beach spots in other parts of the Philippines. In Pagadian, in particular, there are beaches and islands that will make one believe that there is such a thing as a secluded paradise on Earth.

Radiocarbon Dating is used on organic objects only, so the fact that your whole example is based on inorganic rocks and radio carbon dating only suggests that you do not know with any detail or understanding the topic that you are discussing.

Graphs, charts, and images can be used to identify patterns in data. Hook 5 minutes As students settle down for the day’s lesson, I present the following video and ask, “How do we know that all of these events have happened? I follow up with the question, “Well, how do we know what happened before there were people to write things down? Explain 1 10 minutes I tell the students that today’s lesson will help them understand several big ideas that scientists use to determine the history of the Earth, and begin the following presentation.

Throughout the presentation, there are several opportunities for the students to Think-Pair-Share answers to the embedded questions. The Relative Age of Rocks Activity 1 5 minutes When we reach slide 6 of the presentation, I distribute the ” letter cards ” one set per table , and tell the students that their first task is to organize them in order, with oldest CT at the bottom. I explain that “new letters” cannot just appear, there has to be something linking each of the cards to the next.

I remind the students that as they are working, it is not enough to place the cards in the correct order, they must also be able to explain why they are placing each card in that particular order, and should be ready to explain their reasoning SP7. The order of the cards is: Law of Superposition Cards Explain 2 15 minutes I continue with the presentation slides , stopping for quick Think-Pair-Share , at each of the embedded questions.

By having several predetermined stopping points, I am able to give students time to interact with all these new concepts, and turn the presentation into a more interactive learning experience. I tell the students that, as before, they must organize the fossil record from oldest to newest, and be able to explain their choices. The letters on the bottom right of the cards spell the word RELATIVE, and are there to give me a quick check-in as I am circulating the room listening to the students’ explanations.

Absolute vs Relative Dating

Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. All methods can be classified into two basic categories: Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events. Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.

These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials. This method includes carbon dating and thermoluminescence.

Lesson should be introduced by reviewing the 2 broad ways scientists age rocks (relative dating and radioactive dating). Also, review what a half-life is (info given the day prior during lecture/ notes/ reading). New information needed to be introduced with parent and daughter isotopes.

Pin3 Shares 28 The ocean is one of the biggest mysteries of mankind. People search out facts about the ocean for many reasons. Some are students looking for answers. Some seek to learn more out of pure curiosity. Others may be looking to impress friends or family. Whatever your motivation we have created this list of interesting facts about the ocean to document some of the more captivating facts about the largest bodies of water on planet earth.

Three-quarters of this planet is covered by water bodies, with the biggests ones being the five oceans the Atlantic, Pacific, Southern, Indian, and Arctic oceans. Ninety four percent of all life forms on Earth are aquatic. Oceans have an average depth of two and a half miles ft. The ocean is three percent salt. Its salinity is estimated to be around 34 to 36 ppt parts per thousand , whereas fresh water has a salinity of 0 ppt.

Marine biologists estimate that only two-thirds of marine life have been documented and studied. There are millions more species that remain to be discovered.

Unlike the radioactive isotopes discussed above, these isotopes are constantly being replenished in small amounts in one of two ways. The bottom two entries, uranium and thorium , are replenished as the long-lived uranium atoms decay. These will be discussed in the next section. The other three, Carbon , beryllium , and chlorine are produced by cosmic rays–high energy particles and photons in space–as they hit the Earth’s upper atmosphere.

Very small amounts of each of these isotopes are present in the air we breathe and the water we drink. As a result, living things, both plants and animals, ingest very small amounts of carbon , and lake and sea sediments take up small amounts of beryllium and chlorine The cosmogenic dating clocks work somewhat differently than the others. Carbon in particular is used to date material such as bones, wood, cloth, paper, and other dead tissue from either plants or animals.

To a rough approximation, the ratio of carbon to the stable isotopes, carbon and carbon , is relatively constant in the atmosphere and living organisms, and has been well calibrated.

Departures from this assumption are quite common, particularly in areas of complex geological history, but such departures can provide useful information that is of value in elucidating thermal histories. A deficiency of 40 Ar in a sample of a known age can indicate a full or partial melt in the thermal history of the area. Reliability in the dating of a geological feature is increased by sampling disparate areas which have been subjected to slightly different thermal histories.

Ar—Ar dating is a similar technique which compares isotopic ratios from the same portion of the sample to avoid this problem.

Archaebacteria , Chromista , and Archezoa Thomas Cavalier-Smith thought at first, as it was nearly consensually admitted at that time, that the difference between eubacteria and archaebacteria was so great particularly considering the genetic distance of ribosomal genes that they needed to be separated into two different kingdoms, hence splitting the empire Bacteria into two kingdoms.

He then divided Eubacteria into two subkingdoms: Negibacteria Gram negative bacteria and Posibacteria Gram positive bacteria. Technological advances in electron microscopy allowed the separation of the Chromista from the Plantae kingdom. Indeed, the chloroplast of the chromists is located in the lumen of the endoplasmic reticulum instead of in the cytosol.

Moreover, only chromists contain chlorophyll c. Since then, many non-photosynthetic phyla of protists, thought to have secondarily lost their chloroplasts, were integrated into the kingdom Chromista. Finally, some protists lacking mitochondria were discovered. As a result, these amitochondriate protists were separated from the protist kingdom, giving rise to the, at the same time, superkingdom and kingdom Archezoa.

This was known as the Archezoa hypothesis. This superkingdom was opposed to the Metakaryota superkingdom, grouping together the five other eukaryotic kingdoms Animalia , Protozoa , Fungi , Plantae and Chromista. Six kingdoms[ edit ] In , Cavalier-Smith published a six-kingdom model, [3] which has been revised in subsequent papers.

They are too much of a national symbol of the north to be performing anywhere else but at the opening ceremony. I suppose the exact programme of the ceremony should be kept secret until the very beginning of the show so no one would know in advance.

Eruption styles and volcano formations[ edit ] Eruption types and examples Hawaiian eruptions Hawaiian eruption: Hawaiian eruption Hawaiian eruptions are passive eruptions characterized by effusive emission of highly fluid basalt lavas with low gas contents. Like other Hawaiian eruptions, the relative volume of ejected pyroclastic material is less than that of all other eruption types. The main phenomenons during Hawaiian eruptions is steady lava fountaining and the production of thin lava flows that eventually build up into large, broad shield volcanoes.

Eruptions are also common in central vents near the summit of shield volcanoes, and along linear volcanic vents radiating outward from the summit area. Lava advances downslope away from their source vents in lava channels and lava tubes. Eve Cone , one of the best preserved cinder cones in Canada. In Canada, cinder cones form when lava fountains release fragments of lava that harden in the air and fall around a linear volcanic vent. The rock fragments, often known as cinder or scoria , are glassy and contain gas bubbles “frozen” into place as magma exploded into the air and then cooled quickly.

Some of the lava is not fragmented and flows from the vent as a lava flow. As lava lakes solidify, they create a grey-silver crust that is usually only a few centimeters thick.

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age. Scientists also use direct evidence from observations of the rock layers themselves to help determine the relative age of rock layers. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed.

Student Reading Pick up a rock, any rock, and examine it. Can you see any way to determine its age? Is it ten years or ten million years old? You cannot tell just by looking at it. For this reason, scholars for nearly all of human history had no way of knowing the age of the Earth or its rocks. Up to the 19th century, for example, many people in Europe believed the Earth was only about 6, years old. Yet, to those who looked, the Earth offered bizarre clues of a deeper past.

One such person was Leonardo da Vinci, the great artist and engineer who was also an extraordinary scientist and observer of the world around him.

Geologic Time The most obvious feature of sedimentary rock is its layering. This feature is produced by changes in deposition over time. With this in mind geologist have long known that the deeper a sedimentary rock layer is the older it is, but how old? Although there might be some mineral differences due to the difference in source rock, most sedimentary rock deposited year after year look very similar to one another. This means that a quartz sandstone deposited million years ago will look very similar to a quartz sandstone deposited 50 years ago.

Making this processes even more difficult is the fact that due to plate tectonics some rock layers have been uplifted into mountains and eroded while others have subsided to form basins and be buried by younger sediments. With out individual time stamps the process of dating these structures could become extremely difficult. To deal with many of these problems geologists utilize two types of geologic time: Relative time places events or formations in order based on their position within the rock record relative to one another using six principles of relative dating.

Relative time can not determine the actual year a material was deposited or how long deposition lasted; it simply tell us which events came first. This process lead to a system of time containing eons, eras, periods, and epochs all determined by their position in the rock record. For example, rocks of the Phanerozoic eon are found on top of rocks from the Proterozoic eons therefore rocks of the Phanerozoic are younger than rocks of the Proterozoic.
