Paleontology

Paleontology is the study of prehistoric life and an organism's interaction with other organisms and the environment. It is a science that attempts to explain causes, rather than to conduct experiments to observe effects, and is often based on fossil evidence. Questions here have to do with anything that pertains to paleontology.

What years did the paleozoic era start and end?

The Paleozoic Era started around 541 million years ago and ended about 252 million years ago, spanning a duration of approximately 289 million years.

How do you build a house in the Mojave desert?

When building a house in the Mojave Desert, it is important to consider the extreme temperatures, limited water supply, and potential for desert wildlife encounters. Utilizing materials and designs that offer good insulation against heat and cold, incorporating sustainable water and energy systems, and careful planning for landscaping to minimize water usage are all essential factors to consider. Consulting with local experts and obtaining necessary permits are also crucial steps when constructing a house in the desert environment.

What side of the rock does lichen grow on?

As far as I know it grows at the side where sunlight doesn't falls. However, you can reach best Biology tutors who can answer you in detail and much more understandable form. I tried them and found very helpful. You can get them at www.tutorskingdom.com and they will help you out for sure...!!!

The Cambrian explosion resulted in the evolution of the first?

complex multicellular organisms with hard parts, such as shells and skeletons. This period saw the emergence of diverse marine life forms, including arthropods, mollusks, and chordates, laying the foundation for future evolutionary developments.

How many continental plates are there on the Earth?

The most common division of the earth's landforms is seven (7) continents ... Africa, North America, South America, Antarctica, Asia, Australia, and Europe. There are actually many continental plates. There are 7 primary plates (African Plate, North American Plate, South American Plate, Antarctic Plate, Eurasian Plate, indo-Australian Plate, and the Pacific Plate). In Addition there are 8 secondary plates (Arabian Plate, Caribbean Plate, Cocos Plate, Indian Plate, Juan de Fuca Plate, Nazca Plate, Philippine Plate and the Scotia Plate. These plate are commonly shown on continental plate maps. There are also a large number of tertiary plates.

What the divisions of Mesozoic Era called?

they were the cretatious triassic and jurassic

What is the evolutionary history of primates based on?

The evolutionary history of primates is based on fossil evidence, molecular studies, and comparative anatomy. Fossil records show the gradual development of primate characteristics over time, while molecular studies help determine how closely related different primate species are. Comparative anatomy helps identify shared characteristics across different primate species and their common ancestors.

A relative age of the rocks of the earth's crust can be determined by using the laws of what?

There are three laws of science that scientists use to date the crust by studying the layers of rocks. These laws are called the Law of Original Horizontality, the Law of Superposition, and the Law of Faunal Succession.

Where is chalcopyrite found?

Chalcopyrite is commonly found in hydrothermal veins associated with copper deposits worldwide. It is also found in some sedimentary rocks and metamorphic environments. Major sources of chalcopyrite include regions like Chile, Peru, the United States, and Australia.

What are 2 reasons why it is difficult for scientist to study Precambrian rocks?

  1. Precambrian rocks are often heavily metamorphosed, making it challenging to determine their original composition and age accurately.
  2. The lack of easily recognizable fossils in Precambrian rocks makes it difficult to establish a timeline of events and understand the evolution of life during that time.

Is the following sentence true or false it is very difficult for scientists to learn about earths past environments by studying fossils?

False. Scientists can learn a lot about Earth's past environments by studying fossils. Fossils provide valuable information about past climates, ecosystems, and the evolution of life on Earth. By studying fossils, scientists can reconstruct past environments and gain insights into how they have changed over time.

What is a current era?

As far as I'm aware we are in the 'digital age' the last was the 'atomic age'.

In the geological time scale we are currently in the Cenozoic era which dates from 65.5 million years ago to the present day.

What type of animal lived only during mesozoic era?

The type of animal that lived only during the Mesozoic Era (Age of Reptiles) were the dinosaurs. They evolved during the late Triassic and the Jurassic periods, and were the largest land creatures during the Cretaceous period of the era.

The Cambrian Period was part of what era?

The Cambrian Period was from about 543 to 490 million years ago. It is the earliest period in the Paleozoic ("old life") Era. Until relatively recently paleontologists thought this marked the beginning of life. Primitive life is now know from the Pre-Cambrian Eon.

What must happen in order for new species to evolve?

Reproductive isolation.

If a species is divided into two groups, which cannot interbreed, then each group will gradually adapt to their new environment . Eventually the two groups will be so different that members from the different groups can no longer mate with one another and produce fertile offspring. This means that the two groups have become different species.

At what speed does earth travel around the sun?

The speed of the Earth in its orbit around the Sun varies somewhat, because our orbit is an ellipse. When the Earth falls closer to the Sun, we speed up, and as the Earth moves away, we slow down a little. But the eccentricity of the ellipse - the amount that it differs from a circle - is fairly low, so the difference isn't all that great. So on average, the Earth is traveling about 67,000 miles per hour in our path around the Sun.

What type of rock will most likely contain the fossils of animals that once lived in the ocean?

Sedimentary rock is the most likely type of rock to contain fossils of animals that once lived in the ocean. This is because sedimentary rocks form from the accumulation and compaction of sediments, which can entomb and preserve the remains of organisms over time.

What could you conclude about an area where new sea floor was forming from cooling magma?

The area likely lies along a mid-ocean ridge where tectonic plates are pulling apart. As the magma rises to the surface and cools, it solidifies into new oceanic crust. This process, known as seafloor spreading, is a key component of plate tectonics.

What speed dose earth travel around the sun?

Earth travels around the sun at an average speed of about 67,000 miles per hour or 107,000 kilometers per hour. This fast speed allows Earth to complete one orbit around the sun in about 365.25 days.

What is the well known name for the largest variety of grass?

Bamboo is the well known name for the largest variety of grass, known for its tall and sturdy stems that can reach significant heights. It is a versatile plant used for various purposes such as construction, furniture, and food.

Do lemons kill plants?

Well, the acidity can cause the roots to burn out and make the acid's pH too high for a plant. This varies in different plant types.

What was the climate like near the end of the mesozoic era?

The climate before the Mesozoic period/era was a relatively warm climate. The Mesozoic Era was an interval of geological time from about 252 to 66 million years ago and is also called the Age of Reptiles.

Cenozoic Era life-forms include?

The Cenozoic started 65.5 million years ago, and it continues through the present day. The Cenozoic is when flowering plants and mammals diversified and came to dominate terrestrial flora and fauna, respectively. Mammals started out small, but evolved into all the forms that exist today, from elephants to lions to kangaroos to bats to sea lions.

How do jetties and groins affect the longshore current?

It affects is because the material deposited on the beach formed a spit and it erodes the beach because when the waves are strong the material erodes the beach

Not much info but hope it helps.
