What is the meaning of radiation zone?
The radiation zone is a region in the interior of a star where energy is transported outward by electromagnetic radiation, primarily in the form of photons. In this zone, energy is carried through the star's layers by the absorption and re-emission of photons. The radiation zone is located between the core and the convection zone of a star.
In what form solar energy leaves the core of the sun?
Solar energy leaves the core of the sun in the form of electromagnetic radiation, primarily as visible light and heat. This energy travels through the sun's layers until it reaches the surface and is then emitted into space in the form of sunlight.
How long does it take Photons at the core to the surface?
It can take thousands to millions of years for a photon to travel from the core of the Sun to its surface due to the dense interactions and scattering of photons within the Sun's outer layers. Once a photon reaches the surface, it takes only about 8 minutes to travel to Earth.
What are the suns three main layers?
The three main layers of the sun are the core, the radiative zone, and the convective zone. The core is where nuclear fusion occurs, converting hydrogen into helium. The radiative zone is where energy is transported by photons, while the convective zone is where energy is transferred by gas moving in convection currents.
Two atmospheric layers that contain air as warm as 25c?
The troposphere and stratosphere are the two atmospheric layers that can contain air as warm as 25°C. The troposphere is where most of the Earth's weather occurs and its temperature decreases with altitude. The stratosphere is located above the troposphere and contains the ozone layer, which absorbs and scatters UV radiation.
How does energy in the form of light photons travel through the many layers of the sun?
Energy in the form of light photons travels through the many layers of the sun by a process called radiation. In the sun's core, nuclear fusion creates high-energy photons that travel outward through the radiative zone, where they bounce around and gradually lose energy. Eventually, the photons reach the convective zone, where they move more freely and reach the sun's surface as visible light.
What layer of the rain forest do the spiders live in?
There are species in all layers.
Why are your fingers wrinkled without going in the bath?
there are 2 layers of skin the first is pourus the second is not so the water gets between the layers, first layer absorbs moisture and so alters shape.
Why are more recently deposited rock layers more likely to contain fossils resemble existing species than older rock layers?
The more recent rock layers will contain fossils that are more similar to current species because of evolution. The older the fossils, the more evolutionary changes will exist between them and current species which accounts for the greater differences.
Which two layers of the atmosphere heat up because they absorb high energy rays from the sun?
The stratosphere and the thermosphere are the two layers of the atmosphere that heat up because they absorb high-energy rays from the sun. The ozone layer in the stratosphere absorbs UV radiation, while the thermosphere absorbs extreme ultraviolet and X-ray radiation.
How does the position of fossils in layers show evolutionary changes?
Assuming the layers aren't deformed, the lowest deposition layers are the earliest. Later deposition layers accumulate on top of the earlier layers. Thus, the lowest layers have the earliest fossils, and the highest layers have newer fossils. By comparing the features of early and late fossils of a species, you can determine some of its evolutionary changes. Of course, not all features survive in a fossil - soft tissues, for example.
Why is the rain forest able to support such a large variety of species?
because of the layers in the trees
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers scientists can learn what?
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers, scientists can learn about the relative ages of the fossils. This helps in understanding the sequence of events in Earth's history and the evolutionary relationships between different species.
What are the layers of ecological organization?
The layers of ecological organization are individual organisms, populations of a single species, communities of multiple species, ecosystems which include both biotic and abiotic factors, and finally the biosphere which encompasses all ecosystems on Earth.
Does a chamelion lay eggs or young?
Both !... While most species are oviparous (egg-layers) there are also some species that are ovoviviparous (live-bearers).
Do giant danios lay eggs?
All members of the Danio and Brachidanio species are egg layers.
How many layers of fur do sea lions have?
Beginning in the 1790s, and especially during the 19th century, fur seals were hunted because their fur was so valuable. A select few species suffered dramatic declines, but are now recovering. Most species are now protected and hunting is mostly limited to subsistence harvest (for Native Americans and Eskimos).
