Paleontology

Well, it depends on how much detail you want. Carbon-dating is actually very accurate to within a few thousand years. This sounds like a long time to us, but when you are talking about a fossil that is millions of years old, a few thousand years is nothing. Of course, you can't say that a fossil has been in the ground since 1:27pm, Monday 5th June, 34,050,389 BC, but considering the time scales involved, we can date fossils pretty accurately.

This question makes no sense, because there are plenty of transitonal fossils.

(I might have spelled one or two incorrectly)

Astronauts were able to conduct experiments in space. The unique microgravity environment allows for studies on various topics such as biology, physics, and materials science that cannot be easily replicated on Earth. Conducting experiments in space provides valuable insights into how different processes and phenomena behave in microgravity conditions.

They develop a cytoplasmic hair-like elongation which increases its surface area for more absorption. It also has a large number of mitochondria which provides energy needed for the active uptake of minerals.

The main reason is that many different organisms went extinct along with the dinosaurs, both on land and in the sea. In all, about 65% of all species on Earth went extinct. Furthermore, many groups of organism disappear from the fossil record very suddenly. This evidence suggests that a cataclysmic event devastated numerous ecosystems around the world.

Nothing at all. Paeleontologists chose a time where significant numbers of hard-shelled animal fossils first appeared in rocks.

It was initially believed that these were evidence of the first life on earth. As such it was decided by stratigraphers that this was a sensible point in time to create a boundary between the pre-cambrian and the newly named eon (which we are still in) - the phanerozoic, which literally means "new life".

Sporoderm is the outermost protective wall around the pollen grain or microspore.

It is made up of many layers. The two main layers are Exine and Intine. Exine is outer while Intine is inner layer of sporoderm.

The sandwich is named after John Montagu, the 4th Earl of Sandwich, who is said to have ordered his food to be served between two slices of bread so he could eat while playing cards. This way of serving food became popular and eventually led to the creation of the sandwich.

There's only one way that they can be formed over millions of years. An animal dies, it soon is compressed with heat/pressure and turns to sediment. The only other way is if you want to make a false fossil. Just use plaster.

Accualy, no. fossils can be formed by....

1. sediment piling on the substance and creating a mold

2. an orginism may be incased in ice, which counts as a fossil

3. mud, bogs, and mucky water may presurve an orginism

4. heat and pressure makes a metamorphic rock, and only sedimentary rock can weild fossils

HOPE I HELPED ^^ IF I DID CHECK OUT JEALOUSNOTAHATER ON YOUTUBE, SUBSCRIBE, RATE, AND COMMENT TOO.

I kept his answer so you could see how wrong he is lol :)

oh, they can also be incased in amber, a sticky substance that ozzes out of trees to protect them from paricites

The three theories of the formation of the solar system are the nebular theory, the planetesimal hypothesis, and the gravitational instability theory. The nebular theory proposes that the solar system formed from a rotating disk of dust and gas, while the planetesimal hypothesis suggests that small, solid bodies collided and accreted to form planets. The gravitational instability theory proposes that clumps of material in a protoplanetary disk collapsed under their gravity to form planets.

Extrusive rocks are... extruded... onto the surface as the lava that we all think of. It cools fairly quickly, into rocks with fairly small crystals (might need a magnifying lens to see them). The exact chemistry of the parent magma will determine the type of rock. Oceanic volcanoes are generally basaltic (mafic or ultramafic), continental are generally granitic (felsic or intermediate). They're put down in "relatively thin" layers.

Intrusive rocks cool for thousands of years beneath the surface in huge plutons or batholyths. This allows them to grow very large crystals (easily seen by the unaided eye). These intrusive rocks are almost always granitic-type rock.

The mass extinction, known as the Permian extinction, affected both plants and animals on land and in the seas. Scientists do not know what catastrophic events caused the mass extinction, many kinds of organisms suddenly became extinct, as much as 90% of Marine species may have died out.

The first step in conducting a scientific investigation is to define the problem or research question that you want to address. This involves clearly stating the objective of the study and identifying what you want to learn or discover through your research.

Some creationists use this argument as "evidence" against evolution.

However, the flaw in their argument is that fossils do occur, they are in order, they are separated by a large time difference, and they are transitional.

The argument is commonly called the "missing link" problem, and when Darwin first developed his ideas, it actually was. He explicitly recognised it as such, and came up with several ways it would either deny or help support his theory (such as by finding rabbits in the PreCambrian era, or by the presence of missing links, which were later found). However, in the 140 years since then, we have uncovered thousands of fossilized species, each of which is a tranistional form in the evolution of several other species.

The best example is that of our own ancestry; several species have been discovered, each getting closer and closer to human as we know it, and at the same time, further from the simple ape-like mammals we began as. All of this happened - according to the geological timeframe - over a period of several million years.

During the Paleozoic Era, the continents were mostly joined together as a supercontinent called Pangaea. In the Mesozoic Era, Pangaea began to break apart, leading to the formation of the modern continents. Throughout the Cenozoic Era, the continents continued to move to their current positions due to the process of plate tectonics.

Early organisms in the Precambrian era converted carbon dioxide to oxygen through photosynthesis. This process eventually led to the increase in atmospheric oxygen levels, paving the way for the evolution of more complex life forms.

The largest extinction event known is the Permian-Triassic Extinction Event, 250 million years ago. It is nicknamed "The Great Dying" in reference to how 96% of all known marine animals and 70% of all known terrestrial vertebrates at the time went extinct due to climatic changes because of volcanic eruptions and the formation of Pangaea.

There are various eras in history, including the Paleolithic era, Neolithic era, Bronze Age, Iron Age, Middle Ages, Renaissance, Industrial Revolution, and Modern era. Each era is characterized by distinct social, cultural, and technological developments.

Without Earth's rotation, the air at the equator would move from high to low pressure in a straight line towards the poles. This is because air moves from areas of high pressure to areas of low pressure, creating a simple north-south airflow pattern.

The mass extinction that is believed to have eliminated larger dinosaurs 65 million years ago. Smaller dinosours survived, their descendants are today's reptiles. The mass extinction is believed to have been caused by an asteroid that collided with Earth. For more information, read the Wikipedia article on "Cretaceous-Paleogene extinction event", or search for this term on your favorite search engine.

In the southern half of Australia, shadows point south at midday because the sun is positioned in the northern part of the sky. The angle of sunlight creates shadows that extend in the opposite direction, which is south in this case. This phenomenon occurs due to the tilt of Earth's axis, causing the sun's path to be more direct in the Southern Hemisphere.

A preserved fossil is an organism or Animal that has been PERFECTLY PRESERVED for lots of years, or however old it may be. For example, a wooly mammoth frozen in the ice for millions of years would be known as a preserved fossil.
There are 2 different types of fossil preservation- preservation with alteration and without. With alteration also has different types. The type of organism you are looking for depends on the how it was preserved.
