Choose the best methods for finding the absolute dates of different rock layers. You will need the Adobe Flash Player to view this. This interactive asks you to choose the best absolute dating method for each layer of rock in a cliff. Your choice will depend on the material present in each rock. We have found this cliff and collected samples from the layers of sedimentary rocks. We know the oldest rocks are at the bottom and the youngest are at the top, but we want some actual dates. Drag and drop the rock sample from each layer onto the dating method you think will tell us its age. Name: Radiocarbon dating Material used: Organic remains such as wood and seeds Age range: Younger than 60, years ago How it works: Measures the amount of radioactive carbon in the organic remains of living things. Name: Fission track dating Material used: Volcanic glass, zircon and other crystals Age range: 10, to million years ago How it works: Measures radioactivity by counting tracks left in crystals by decaying uranium atoms.

Variety reports that Dave Bautista Guardians of the Galaxy , Blade Runner will join the cast for the second season. A half-hour comedy drama, it is set in the past but features writing to relate to a modern audience. The show is meant to help introduce toddlers to the simplest core concepts of coding as a means of helping people.

This extends to animated series, which provide younger viewers with some of their earliest glimpses of the broader world. Capturing the goofy, slapstick tone of the real-life Harlem Globetrotter performances, the series showed the talented, if lovably clueless, band of athletes who don the standard stars and stripes, including Meadowlark Lemon, Geese Ausbie and Curly Neal. Following the standard Saturday-morning-cartoon formula, each episode of the series had the protagonists encounter some new obstacle that they good-naturedly overcame with the use of their talents — and usually some silly costumes and wigs.
Later the Globetrotters joined up with Scooby-Doo and friends to help solve some mysteries — which is how I first encountered these brilliant ballers as a kid. Before Bill Cosby faced a flurry of sexual assault accusations and a prison sentence, he was known as an essential figure in the world of Black television. These moral stories were most memorable for their entrancing illustrations, by the artist Varnette Honeywood.
What was missing from the early geologic time scale? While the order of events was given, the dates at which the events happened were not. With the discovery of radioactivity in the late s, scientists were able to measure the absolute age , or the exact age of some rocks in years. Absolute dating allows scientists to assign numbers to the breaks in the geologic time scale.
Radiometric dating and other forms of absolute age dating allowed scientists to get an absolute age from a rock or fossil. In locations where summers are warm and winters are cool, trees have a distinctive growth pattern.

Derry studio Dog Ears to make new app cartoon. An Emmy-nominated cartoon series developed in Londonderry featuring a family of Irish puffins is to be the first animated feature length film produced in Northern Ireland. The Puffin Rock Movie is set for release in the spring of The film will be filmed in Derry, Kilkenny and in Tianjin in China. The movie follows the huge international success of the animated series aimed at pre-school children.
Fionnuala Deane, Managing Director of Dog Ears, said there was much excitement around the movie deal, signed by the Irish media firms and Penguin Books, part-owner of the Puffin Rock brand. She said the Derry firm, who set up an animation studio in the city to produce the series, has “big hopes for it reaching family audiences across the globe”. In China alone, the series has been streamed more than million times. The series was nominated for an International Emmy Kids Award in

The beginning of the story starts at the bottom of the canyon and moves forward in time as you get closer to the rim. Stratigraphy is the study of the rock layering, and reveals a wealth of information about what Earth was like when each layer formed. In the Grand Canyon, there are clear horizontal layers of different rocks that provide information about where, when, and how they were deposited, long before the canyon was even carved.
The Law of Superposition states that sediment is deposited in layers in a sequence, the oldest rocks are on the bottom and the youngest rocks are on the top, similar to the way that sand piles up in an hour glass. This principle is a key part of determining the relative age of a rock layer.

Potassium-Argon Dating Potassium-Argon dating is the only viable technique for dating very old archaeological materials. Geologists have used this method to date rocks as much as 4 billion years old. It is based on the fact that some of the radioactive isotope of Potassium, Potassium K ,decays to the gas Argon as Argon Ar By comparing the proportion of K to Ar in a sample of volcanic rock, and knowing the decay rate of K, the date that the rock formed can be determined.
Dating rocks Gaining estimates of ages of rocks is crucial for establishing not only the history of geological events but also for determining the rates of geological.

HTML5 canvas, which started as an experiment from Apple, is the most widely supported standard for 2D immediate mode graphics on the web. Many developers now rely on it for a wide variety of multimedia projects, visualizations, and games. However, as the applications we build increase in complexity, developers inadvertently hit the performance wall. This article aims to consolidate some of this body into a more readily digestible resource for developers.
This article includes fundamental optimizations that apply to all computer graphics environments as well as canvas-specific techniques that are subject to change as canvas implementations improve. In particular, as browser vendors implement canvas GPU acceleration, some of the outlined performance techniques discussed will likely become less impactful.

Using cosmogenic nuclides in glacial geology Sampling strategies cosmogenic nuclide dating Difficulties in cosmogenic nuclide dating Calculating an exposure age Further Reading References Comments. Geologists taking rock samples in Antarctica for cosmogenic nuclide dating. They use a hammer and chisel to sample the upper few centimetres of the rock. Cosmogenic nuclide dating can be used to determine rates of ice-sheet thinning and recession, the ages of moraines, and the age of glacially eroded bedrock surfaces.
It is an excellent way of directly dating glaciated regions. It is particularly useful in Antarctica, because of a number of factors:. Cosmogenic nuclide dating is effective over short to long timescales 1,,, years , depending on which isotope you are dating. Different isotopes are used for different lengths of times.
This long period of applicability is an added advantage of cosmogenic nuclide dating.

Lead—lead dating is a method for dating geological samples, normally based on ‘whole-rock’ samples of material such as granite. For most dating requirements it has been superseded by uranium—lead dating U—Pb dating , but in certain specialized situations such as dating meteorites and the age of the Earth it is more important than U—Pb dating. There are three stable “daughter” Pb isotopes that result from the radioactive decay of uranium and thorium in nature; they are Pb, Pb, and Pb.
These daughter isotopes are the final decay products of U and Th radioactive decay chains beginning from U, U and Th respectively. With the progress of time, the final decay product accumulates as the parent isotope decays at a constant rate. This can be expressed by the following decay equations:.
