Paleontology

Gypsum is composed primarily of calcium sulfate dihydrate. It contains calcium, sulfur, and oxygen atoms arranged in a specific crystal structure. No other minerals are present in significant amounts in gypsum.

The first documented hacking incident dates back to the 1960s when MIT students altered the school's computer operating system. However, the term "hacker" has evolved over time to refer to individuals who use their programming skills for various purposes, both legal and illegal.

The tropical rainforest supports a high number of species due to its stable warm climate, abundant rainfall, and diverse habitats. These factors provide a variety of niches for different species to thrive, leading to high biodiversity. Additionally, the complex relationships and interactions between species in the rainforest contribute to its rich diversity.

Fast moving rivers are capable of carrying larger rock particles than slow moving rivers.

Fossil fuels are classified as non-renewable sources. Examples of fossil fuels are coal and petroleum. They are termed non-renewable because they were produced organically over millions of years. if the limit quantity of fossil fuels are used up, it will be difficult to replace them.

No, dinosaurs did not appear until the Mesozoic Era, which followed the Paleozoic Era. Dinosaurs first appeared around 230 million years ago at the start of the Triassic period. The Paleozoic Era ended around 252 million years ago.

Pollution is destroying the balance of several food webs on the planet.

The treaty ushered in an epoch of peace and goodwill.

Tropical rainforests are forests with warm temperatures, wet weather, and lush plant growth. They are found in regions near the equator and have high levels of biodiversity due to the favorable conditions for plant growth.

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.
