Margin of Error01:27

Margin of Error

7.7K
The margin of error is also called the maximum error of an estimate. The margin of error is the maximum possible or expected difference between the observed sample parameter value and the actual population parameter value. For proportion, it is the maximum difference between the value of sample proportion obtained from the data and the true value of population proportion. As the true value of the population parameter is not known, the margin of error is calculated using the sample statistic.

The Carbon Cycle01:14

The Carbon Cycle

44.2K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

The Sulfur Cycle01:22

The Sulfur Cycle

52.1K
Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...

Ecological Succession02:17

Ecological Succession

21.7K
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

What is Evolutionary History?

43.8K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

    Summary
    This summary is machine-generated.

    New evidence confirms end-Cretaceous, peralkaline volcanic rocks in Greenland. These Kap Washington Group rocks likely formed in a continental rift, not the Yermak hot spot, aiding Arctic tectonic reconstructions.

    Area of Science:

    • Geology
    • Geochemistry
    • Tectonics

    Background:

    • The Kap Washington Group volcanic rocks in North Greenland, discovered in 1969, have been central to Arctic geotectonic models.
    • Previous interpretations linked these rocks to the Yermak hot spot and the Eurasia Basin opening.

    Purpose of the Study:

    • To clarify the age and chemical nature of the Kap Washington Group volcanic rocks.
    • To reassess their geotectonic setting and relationship to Arctic plate tectonics.

    Main Methods:

    • Geochemical analysis of volcanic rock samples.
    • Geochronological dating to determine the age of volcanicity.
    • Tectonic modeling to evaluate different origin hypotheses.

    Main Results:

    • The Kap Washington Group volcanism is confirmed as end-Cretaceous in age.
    • The rocks are characterized by a peralkaline chemical signature.
    • A direct genetic link to the Yermak hot spot is deemed improbable.

    Conclusions:

    • The Kap Washington Group rocks originated in a continental extensional rift environment.
    • This volcanism predates the break-up of the Laurasian plate in the Arctic.
    • The findings provide crucial age constraints for poorly understood Arctic tectonic events.
