Paleontology

Permian refers to a geologic period that occurred between 299 million and 252 million years ago. It is known for being the last period of the Paleozoic Era and marked the dominance of reptiles, the origin of mammals, and the diversification of plants. The Permian period ended with the largest mass extinction in Earth's history, wiping out a significant portion of marine and terrestrial life.

It depends on what day of the year it is. In the Northern hemisphere, North of the Tropic of Cancer, at noon local mean time the Sun will be as North as it can be, but it will be South of you. Conversely, in the Southern hemisphere, South of the Tropic of Capricorn, at noon local mean time the Sun will be as South as it can be, but it will be North of you. In between the two tropics, again it will depend on the time of year, and where you are, but the Sun could be directly overhead, or North of you, or South of you.

This is all because the Earth's axis is tilted 23.5 degrees with respect to the plane of its orbit around the Sun.

A fold is formed when rocks bend under stress but do not break, creating a curve or ripple in the rock layers. This can happen due to tectonic forces pushing or squeezing the rocks. Types of folds include anticlines and synclines.

An organic sedimentary rock made of microscopic shells is called limestone. Limestone is mainly composed of calcium carbonate derived from the accumulation of marine organism shells such as shells of foraminifera, coral, and mollusks. Over time, these shells compact and cement together to form solid rock.

Mammals, primates and most sea animals were extinct during the mesozoic era. And what caused this is a comet hit earth and the lack of sunlight that was able to reach earth the plants died out and without a food source so did the dinosaurs

Its a Noun, and here is the definition:

A fossil formed when an animal, plant, or other organism dies and is covered by sediment, it flesh decays and bones deteriorate due to chemical reactions, and a cavity remains below the ground surface; the cavity's interior surface is an 'impression in the general form of the original organism's exterior surface.

Fossil types that provide paleontologists with well-preserved remains of organisms are typically those formed in conditions that allow for the retention of original organic material, such as amber or tar pits. These types of fossils can provide detailed information about the soft tissues or structures of ancient organisms, offering insights into their biology and behavior.

It's called the specific gravity of a material, and it is the weight of a specific volume of material, compared to an equal volume of water, expressed as a number. Galena, for instance, has a specific gravity of 7.4, indicating that it is 7.4 times heavier than water.

Absolute geologic time refers to the chronological age of a rock or event, typically measured in years. It is determined using radiometric dating techniques, which allow for precise dating of rocks and fossils based on the decay of radioactive isotopes. This provides a more accurate and quantitative way to establish the timing of geologic events in Earth's history.

A mold or cast of a fossil can provide insights into the size, shape, and structure of the organism, helping scientists understand its habitat and behavior. By studying the details preserved in the mold or cast, scientists can make inferences about the environmental conditions in which the organism lived, such as whether it lived in water or on land, its feeding habits, or its interactions with other organisms.

The word "granite" comes from the Latin "granum", meaning "grain" in reference to its course granular structure.

Granite is normally a light-coloured igneous rock with grains large enough to be visible with the naked eye. It is formed by the slow crystallization of magma below Earth's surface. Granite is composed mainly of quartz and feldspar with smaller amounts of mica, amphiboles and other minerals found in the area of its origin.

A fern fossil is an example of a preserved ancient plant specimen that provides valuable information about plant evolution, biodiversity, and environmental conditions in the past. By studying fern fossils, researchers can gain insights into the history of plant life on Earth and how plants have adapted to changing climates over millions of years.

That would depend on the environment in which it exists.

The geography theme that is defined as things that shape the surface of the Earth is called "physical geography." This theme explores processes that include landforms, climate, vegetation, and natural hazards that contribute to shaping the Earth's surface.

The science of studying ancient life is called paleontology. Paleontologists use fossil evidence to understand the history of life on Earth, including the evolution of organisms and ecosystems over millions of years. They study fossils to reconstruct past environments, understand patterns of extinction and diversification, and shed light on the origin and development of different species.

A pegmatite is an intrusive igneous rock comprised of coarse, interlocking mineral grains usually above three centimeters in diameter. Although very many pegmatites are granitic in composition, several hundred mineral species have been found in the most famous pegmatites worldwide, including many rare and valuable minerals. A few discovered pegmatite crystals have grown to several meters across.

A mixture of weathered rock and organic matter is called soil. Soil is composed of various proportions of minerals, organic matter, water, and air, and it plays a crucial role in supporting plant growth and providing nutrients for ecosystems.

After an animal dies, the body undergoes decomposition. Bacteria, fungi, and other decomposers break down the organic matter, returning nutrients to the environment. This process helps enrich the soil and supports the growth of new organisms.

Fossil evidence from late Devonian rocks show that some groups of marine organisms experienced significant extinction events, which may suggest a period of environmental upheaval. Sedimentary records also indicate abrupt changes in sea levels and climate during this time. The presence of specific isotopic markers in the rock record can further support the theory of overturning during the late Devonian.

Fossils, which are the preserved remains or imprints of plants and animals from the past, are the most common traces of past life found in Earth's crust. Other traces include trace fossils like footprints, burrows, or coprolites (fossilized feces), as well as microfossils like pollen grains or microscopic shells. Additionally, chemical signatures in rocks or minerals can also provide clues about past life on Earth.

No, the Paleozoic era is the first of three eras in the Phanerozoic eon. It spans from around 541 million years ago to 252 million years ago. The following era is the Mesozoic era, which is the second era in the Phanerozoic eon.

deduce or conclude (information) from evidence and reasoning rather than from explicit statements.

"from these facts we can infer that crime has been increasing"

synonyms: deduce, conclude, conjecture, surmise, reason, interpret

A lancelet is a living organism. It is a type of marine invertebrate with a simple body structure, similar to that of a fish. Lancelets are considered living organisms because they exhibit characteristics of life such as growth, reproduction, and response to stimuli.
