How the sea shell fossils get top of the mountains up to 1300 feet?
Marine fossils form when creatures die and sink to the bottom where there is little oxygen, and are covered with sediment. If sediment continues to accumulate, after many years its weight will crush the deposit, and in combination with well known chemical processes, can cement it into sandstone. Later, if the sea floor it lifted by any of a number of (again, well understood) geological processes, what was once the sea floor can become part of a mountain. Such a mountain can form in a few million years, where fossils have been forming for 3 BILLION years.
Are the white cliffs of dover make from fossils or is the lime made from a chemical reaction?
The chalk that forms the White Cliffs of Dover is primarily made up of calcium carbonate from the remains of microscopic marine organisms which lived millions of years ago. Over time, these remains accumulated on the sea floor and were compressed into chalk through geological processes. So, the cliffs are mainly formed from fossils.
What constitutes grand larceny in the State of New Hampshire?
In New Hampshire, theft of property valued at $1,000 or more is considered grand larceny. This charge is classified as a felony and carries more severe penalties compared to petty theft. The specific definition and penalties can vary, so it's important to consult the state's criminal code or a legal professional for accurate information.
Example problems of carbon dating?
The benefits of carbon dating is that it can give a guide as to the age of an artifact or fossil. Several problems exist with carbon dating.
First, it only goes back so far. After a while, there is not enough radioactive carbon for the machinery to measure.
Second, a sample may be contaminated. If a person picked it up with his bare hands, some of the carbon from his skin may have mixed with the sample.
Third, if you want to know how long ago a cave was first occupied, you may miss the mark completely. People may have used the same garbage dump for over a million years.
What have scientists found out about jellyfish?
Jellyfish (and all cnidarians) stinging mechanism is the fastest cellular process in nature: cnidae, stinging (or sticking) filaments ejected by cnidocytes (stinging cells) receive an acceleration 40 thousands times bigger than earth gravity acceleration. Some jellyfish of the class Hydrozoa can rejuvenate to an early stadium , avoiding death. Japanese scientist proved that jellyfish contain substances that give benefit to human skin.
What landforms are mudslides most likely to form in?
Mudslides are formed most commonly from volcanoes. When it was dry for a certain time period and it rains heavily it can cause a mudslide. It can be caused when a volcano erupts or just because of a hilly area. Areas that have volcanoes are prone to mudslides, hilly areas are too.
Why solar energy is better than biomass?
-can pollute the air if directly burned
-Expensive to install technology to process and recycle wastes
-use up too much land
-Maintaining a supply of the waste product in sufficient quantities to maintain energy production can be difficult
-the burning of biomass produces greenhouse gases, which is dangerous for our earth
-some waste materials may only be available during seasonally (example: at harvest time)
- Could put environments at an even greater risk
*Solar's chance of "running out" in the next dozen millenia ZERO. collection of solar energy is basically a passive one, where as biomass is labor intensive and short termed.
but... that's just an opinion
He cheated 10 years ago and tells now do i forgive him?
Being together over 10 years is amazing and maybe he needed to come clean , so he could move forward -- It sounds like his guilt was really coming to a head .
Even though you are in shock and lost by what he told you , I think you should if you can forgive him , which I totally understand your hurt and pain .
And he should understand how this has affected you and he needs to be man enough to listen and learn until you get past this .
Great Luck to you
To understand the issue more fully you need to understand 'Peak Oil', the point when oil production reaches its maximum and after which it goes into irreversible decline. Although this is roughly halfway through all reserves, after this point oil becomes increasingly expensive and difficult to extract. Since demand for oil will outstrip supply the price will drastically increase after the peak and have huge effects on oil dependent industries: transport, agriculture, manufacturing, the military, medicine and many more.
Many people think the Peak is imminent (within 10 years) or has already happened. Coal reserves can be expected to peak later, in the next 20 - 50 years, but as the world's population keeps growing and consumption of fossil fuels increases (despite the known effects to the climate), it is difficult to predict. Of crucial importance is the fact that the development of alternative, renewable energy sources (wind, solar, nuclear fusion) are reliant on oil use.
A:Oil in about 50 years. Natural gas in about 70 yrs and coal in about 250 yrs.
A:At current consumption and the population growth, scientists have determined that the oil supplies will run out in 500 years. A:Our coal will run out in about 40-50 years at the rate we are going at, according to scientists. If we use less coal and more renewable sources, it is sure it will last much longer, but the high demand for coal in industry is always rising as our world modernizes. A:it takes 500-1000 years A:pessimistically 30-40 years, optimistically ~100A:
Get real people. We have only been using oil for a little over a hundred years in any real capacity. If we have already reached peak production, and usage is increasing every day, than we are in trouble. Cant be too many years left!
A paleontologist (pay-lee-un-TAH-lah-jist) studies the fossils of dinosaurs.
What is the significance of rock and fossil evidence?
fossils indicate the evolutionary history of life .It is the goal of a group of scientists to determine the phylogeny. with the help of fossils we are able to determine anatomical and molecular similarities among the organism.
Name five fossil fuels and their uses?
This is all i know and i hope it helps.
1. OIL- It is nearly run out.
2. SOLAR ENERGY- The sun is above our heads, shining until the world ends. Why not use it? One problem: solar energy is expensive!
3. Hydro electric power- Ever been on a powerful river? That current is strong! The river powers turbines that provide electricity. Water will keep flowing as long as the world is alive! We're already aware of the effects of damming up a river, sometimes causing loss of homes, but it's still a good source of energy.
4. Wind turbines- they help create energy which we use every day.
5. and last of all - Geothermal Power- Hot springs are a natural relaxation spot for many people. They can also be used for power! The steam and hot water can be used to turn turbines, and can also heat houses and buildings. Not only do you have a way to soak and relax, you have a power source, too! Sadly, not too many places in the world are prime spots for this type of power.
Where do you get the Root Fossil in Pokemon Emerald?
It's actually pretty simple to get the Fossil on Pokémon Emerald. First you go to Fallarbor Town, then go all the way to the edge of the town (Route 114). Then, you go to the Fossil Maniac's house. Then go all the way back to the tunnel he dug. The tunnel should be called Desert Underpass. Once you get in, walk as far as possible to the right, and eventually you will see a fossil, and it will be the Fossil you didn't choose in Mirage Tower!
You definetely need the National Pokédex to unlock the tunnel!
Who discovered fossils of ice age animals?
Too many people to count. This year, Robert Taylor found a nearly complete skeleton of a woolly mammoth in Siberia.
There a lot of them who discovered fossils of ice age animals. These people are called paleontologists.
No, caveart is not considered an artifact. Cave art refers to prehistoric drawings and paintings found on cave walls, which are typically considered as archaeological artworks or expressions of early human creativity and cultural practices. Artifacts are typically objects made or used by humans in the past that have cultural or historical significance.
The value of a Medor watch can vary depending on its condition, age, and demand in the market. It is recommended to consult with a reputable watch appraiser or check recent sales of similar watches to get an accurate estimate of its worth.
In the game Spectrobes, fossils are used to revive ancient creatures called Spectrobes. Players must excavate fossils using various tools, then clean and awaken the Spectrobes from their dormant state.Each Spectrobe has its own unique attributes and abilities that can be used in battles against enemies.
The first dinosaur footprints were found in the Late Triassic Period, around 231 million years ago. The fossil discovered on Vega Island in 2009 likely belonged to a Late Cretaceous dinosaur, dating back to around 66 million years ago.
How can scientist use a skull to determine how old the person was at death?
Age at death estimates from the skull are based on the extent to which the various bones of the cranium have fused together. Unfortunately its been shown that the rate at which this fusion takes place is fairly variable, meaning the method is not that accurate.
Where teeth remain these provide a far more accurate indicator.
In practice the most accurate calculations come from taking age at death estimates based on as much of the skeleton as is available, and so studies of just the skull, especially without teeth can only provide a rough estimate at best.
Can any vegetation be found in Antarctica If so what kind?
Yes vegetation can be found on Antarctica but only small pockets here and there. All of the blizzards that Antarctica has permits very little vegetation. The extreme conditions make Antarctica a habitat in which only the hardiest can survive. Very few species have been recorded on the 2% of the continent that is ice-free. They include about 150 types of lichens, 30 mosses, some fungi and one liverwort.
No, there is no vegetation there.
There is no plant life at the South Pole. The only plant life on Antarctica is around the coastal areas. There are microscopic single cell plants called phytoplankton that live and multiply in water, and mosses, lichens and algae that can live under the snow and ice.
When did different fossils including dinosaurs appear?
Fossils appeared continually throughout the history of life; the oldest known fossils are of stromatolites which are thought to be 3.4 billion years old Dinosaur fossils have doubtless been dug up for hundreds of years. The Chinese found "dragon" bones over 2000 years ago - these may well have been dinosaur fossils. In 1676, a large femur was found in England by Reverend Plot - probably from a dinosaur. A report of this find was published by Brookes in 1763.
The first dinosaur to be described scientifically was Megalosaurus; named in 1824, by William Buckland. Buckland (1784-1856) was a British fossil hunter and clergyman who collected fossils. The first dinosaur fossil that was found and described was an iguanadon, but this was described after the megalosaurus.
How did the supercontinent change to seven continents in the time of the dinosaurs?
The supercontinent of Pangea began to rift and break apart between 175-200 million years ago. At first it separated into two landmasses, Laurasia and Gondwanaland. Laurasia separated into Asia, Europe, and North America, while Gondwanaland separated into South America, Africa, Australia, and Antarctica.This was all due to plate tectonics pulling apart the continents.
Do you get back together after a broken engagement?
Rekindling a relationship after a broken engagement is possible, but it requires open communication, trust, and willingness to address the issues that led to the breakup. It is important to take time to reflect on what went wrong and whether both parties are truly committed to making things work. Ultimately, the decision to get back together should be based on mutual understanding and respect for each other's feelings.
What are the columns on a periodic table called?
The columns are called groups (or, sometimes, families). The rows are called periods.
Does State of Pennsylvania require burial vaults for burial?
If the death was not from a contagious disease, no state law requires a casket or a vault. Most cemeteries on their own do require a vault, and most cemeteries dig the grave deeper than DOH regulations. There are numerous reasons for this. If the cemetery uses heavy machinery to dig graves or cut grass, etc., a vault will keep the machinery from damaging the remains. Also as time passes, the remains and wooden coffins disintegrate, which will cause the ground above the grave to sink such that there will be a large depression in the ground. Also, by reason of our geographic location, the ground in Pa. freezes and unfreezes several times throughout the winter season. This tends to push anything in the ground up towards the ground surface. A vault will also protect the remains from scavenging animals. Depending on soil conditions and flood plains the remains could also work their way to surface. During the 1972 hurricane and resulting floods in Pa., coffins floated down the Susquehanna River. A vault tends to hold everything in place. In the case of a body not dead of a contagious disease, burial is to occur within 24 hours of death. Otherwise the body must be embalmed or placed in a hermetically sealed container. [28 Pa. Code 1.23(a).] The Pa. Department of State's Board of Funeral Directors has a similar regulation (funeral directors may also use refrigeration under strict legal standards for bodies not disposed of within 24 hours of death). [49 Pa. Code 13.201(6).]
