What type of Battery does a Fossil brain technology watch have?
Fossil watches with hybrid smartwatch technology use a replaceable coin cell battery, typically a CR2430 or CR2450. These batteries last for several months to a year, depending on usage. It's recommended to use the specific battery type suggested by Fossil to ensure optimal performance.
Why are people still using fossil fuel?
Another contributor wrote:
Burning fossil fuels, as we are doing in industry, transport and for generating electricity, releases carbon dioxide, a major greenhouse gas.
Normally carbon dioxide is removed from the atmosphere by various ways through the carbon cycle, however, carbon dioxide from fossil fuels has been hidden away for millions of years, and only now is being released. The carbon cycle is only able to remove part of this gas. It is this extra gas that is causing global warming. And global warming is causing climate change.
Why are fossils and artifacts important in THE study of anthropology?
Fossils reveal many fascinating facts about the past.
Fossils also help us understand past climates, including ice ages and periods that were warmer than our present climate. Knowledge from the study of fossils is helping geoscientists understand global warming and its effects. By studying the catastrophic extinction of the dinosaurs and many other life forms at the end of the Cretaceous Period, geoscientists have gained insight into the evolutionary implications of impacts by extraterrestrial objects. Investigating the physical and chemical characteristics of fossil organisms that lived during times of drastic climatic change helps us understand the implications of the changes we are making in our own environment.
Get the claw fossil or the root fossil in sapphire?
In Pokémon Sapphire, you can choose to revive either the Claw Fossil into Anorith or the Root Fossil into Lileep. The decision is up to personal preference based on which Pokémon you prefer to have on your team.
Is there a site that offers live chat for fossils?
No: the animals can't chat because they've been dead for millions of years... :-) Try searching under "geology", "palaeontology" or "fossils" with "forum" after the name. How "good" any site you find is, will rather depend on your tastes and interests and level of knowledge.
Can you get unlimited donation points in fossil fighters?
yes just clean fossil rocks that dont have new under the fossil rock in foosil fighters and clean that if its lower score it gets donated to the fossil center and thats how you get donation points
The Archean Eon spans the time from the formation of the Earth until years ago?
The Archean Eon spans from the formation of the Earth around 4.6 billion years ago to approximately 2.5 billion years ago. This eon is marked by the formation of the first continents, the emergence of life in the form of prokaryotic cells, and the development of the Earth's atmosphere.
This process is called fossilization. Minerals from the surrounding rock infiltrate the bone structure, gradually replacing the organic material with minerals such as silica or calcite, turning it into a fossil.
How does determining the ages of igneous rocks help to date fossils?
Determining the ages of igneous rocks helps to establish the age of the rock layer in which fossils are found. By dating the igneous rocks above and below the fossil-containing layer, scientists can narrow down the possible age range of the fossils found within that layer. This helps to provide a more accurate estimate of the fossil's age.
How do people know what the earth was like billions of years ago?
Scientists do not know exactly what happened, but they are able to make educated guesses from volcanic rocks and fossils. From these rocks and fossils, an age can be determined and sometimes what the rock/fossil went through. One example of this is a fossilized dinosaur foot print. From the fossil, scientists can find the species of dinosaur, and when it lived. They can find the age of the fossil similar to how you can find the age of a tree. In a tree, there are many rings and each of these is a layer that forms over the year. This is similar to how you can find the age of a rock/fossil.
One reason Tetragraptus is considered a good index fossil is that Tetragraptus?
evolved rapidly, had a wide geographic distribution, and had a relatively short geological range, making it useful for correlating sedimentary rocks in different locations.
What is the chronological collection of life's remains found in layers of rock?
The answer is the fossil record :D
What can you do to help preserve fossil fuels?
To help preserve fossil fuels, you can reduce your energy consumption by using energy-efficient appliances and vehicles, support renewable energy sources like solar and wind power, and advocate for policies that promote conservation and sustainable energy practices. Additionally, reducing waste and reusing materials can help minimize the need for new fossil fuel extraction.
Who recognized that different layers of rock contained unique collections of fossils?
Geologist William Smith is credited with recognizing that different layers of rock contained unique collections of fossils, which became the basis for the principle of fossil succession and the development of biostratigraphy.
How do scientists find the absolute age of fossils and rock correlations?
Scientists find the absolute age of fossils and rocks through radiometric dating techniques such as carbon-14 dating for more recent samples, and methods like uranium-lead dating for older samples. Rock correlations involve comparing the rock layers in different locations to establish their relative ages based on the principle of superposition and the identification of index fossils.
When do the first eukaryotic cells show up in the fossil record?
The first eukaryotic cells appear in the fossil record around 2 billion years ago during the Proterozoic eon. The oldest known eukaryotic fossils are single-celled organisms called acritarchs. These early eukaryotes eventually gave rise to more complex multicellular life forms.
How do geologists use fossils to determine rocks age what are this fossils called?
Geologists use fossils to determine the age of rocks through a process called biostratigraphy. They identify the specific group of fossils present in the rock layer, known as index fossils, that have a known age range. By comparing the index fossils to a geological time scale, geologists can estimate the age of the rock layer.
How many transitional forms does a fossil record contain?
"Transitional form" is an arbitrary term because every organism, whether living or fossil, is a link in the chain between an ancestral organism and a descendent. The break into new species is gradual rather than sudden. Every fossil is therefore a "transitional form" in the strict sense.
In general, "transitional form" is used specifically to link one modern species with its prehistoric ancestor. In some cases, a form may not be a specific ancestor of an identifiable living species, but it may have general characteristics that indicate the evolutionary path that was being followed. E.g. the bird fossil Confuciusornis may not be ancestral to living birds, but it still indicates the direction of evolution from earlier repties.
There are abundant transitional forms that illustrate e.g. the transition from fish to land animals; the transition from amphibians to reptiles; the transition from dinosaurs to birds; and the transition from early apes to humans.
Because the definition of "transitional form" in the narrow sense (a transition between two set organisms) is variable, it's not possible to give a strict number.
Can you tell the age of the earth from fossils?
no but you can tell the age of the fossil from the age of the rock around it,
you cant tell the age of the earth from fossils is because animals with bones were didnt exist until later in the earth's "life"
What is a fossil and why are they important?
A fossil is the remains or traces of an animal, plant or any organism which lived in the distant past. They give us information on how different life-forms existed then, what the climate was like, how the atmosphere differed from the present time and where they lived in relation to other parts of the world.
Why are there shark teeth fossils in the mountain of NC?
Shark teeth fossils found in the mountains of North Carolina are a result of the area being underwater millions of years ago. During that time, the movement of tectonic plates caused the seabed with shark teeth to be pushed up to form the mountains. The shark teeth fossils are evidence of the region's geological history and ancient marine ecosystems.
Where can you find real dragons?
Dragons have never existed in real life. They belong in the realm of unicorns and mermaids. So, you will never find a real dragon. The closest thing to one is at the National History Museum with the dinosaur bones.
Absence of proof is not proof of absence, they are out there, maybe even in disquise all around you
Why are the hard parts of animals more likely to be preserved as fossils than the soft fleshy parts?
The soft parts are more likely to decompose or be eaten than the skeleton, teeth, etc.
Scientists have discovered that whales' ancestors had vestigial hind limbs, now absent in modern whales. These vestiges are important evidence of a shared ancestry with four-legged land animals. The presence of these anatomical remnants suggests an evolutionary link between modern whales and four-legged animals from a common ancestor.
The oldest vertebrate fossils are those of ------- with no jaws?
Agnatha, also known as jawless fish, are the oldest vertebrate fossils with no jaws. This group includes ancient species like the ostracoderms and the agnathan fish.
