Paleontology

Tiger's eye has a hardness of 7 on the Mohs scale, making it relatively durable for use in jewelry and other decorative items.

The distance between and the mass of the two bodies are the main determining factors.

Their masses and how far apart they are

The age of the Earth is measured in geologic time scales that are divided into eras, which are then further divided into periods, epochs, and ages. The current era we are in is the Cenozoic era, and within this era, we are in the Holocene epoch. These divisions help scientists study the Earth's history and understand how life has evolved over time.

Other that the process of accretion of material which formed the planet, the major event would probably have been the impact of a Mars sized protoplanet with the young Earth which probably led to the creation of the moon. The presence of the moon has contributed greatly to the formation of life which has directly affected a great deal of the geology of the Earth.

During Precambrian time, the atmosphere and oceans formed and plate tectonics began to build up continental landmasses.

The Precambrian era is not divided into periods because the geological record from this time is more limited and less well understood compared to more recent eras. The lack of distinct fossils and rock layers make it challenging to establish clear boundaries for periods within the Precambrian. Instead, geologists have divided it into eons - the Hadean, Archean, and Proterozoic eons.

They wouldn't because at the beginning, no life could live outside of the water due to high percentages of carbon dioxide in the atmosphere. By the time there was enough oxygen to live, there wouldn't be animals that are edible, and the only plants are ferns and conifers. Plus, there is the factor of a dinosaur, because you know, they are kinda of big and some like to eat meat.

About 9 out of 10 Canadians participate in recycling programs, making Canada one of the top recycling nations in the world. Recycling rates vary across provinces and territories, with some regions reporting higher participation rates than others.

Petrified wood is commonly used for decorative purposes, such as ornaments and jewelry. Its unique patterns and colors make it a popular choice for crafting jewelry pieces and display items. It can also be used in landscaping projects and as a material for artistic carvings and sculptures.

A geographer studies land, including its physical features, climate, and human impacts. Geographers analyze landscapes, map territories, and study the relationship between humans and their environment.

1. Impact event: The most widely accepted theory is that a large asteroid impact caused drastic environmental changes leading to the extinction of the dinosaurs.

2. Climate change: Volcanic activity and changes in atmospheric composition could have led to significant climate disruption, affecting the food chain and ultimately leading to the extinction of the dinosaurs.

3. Competition and evolution: The rise of new species, particularly mammals, may have outcompeted dinosaurs for resources, leading to their decline and eventual extinction in the Cretaceous-Tertiary boundary.

A rock that contains fossil seashells was most likely formed as a result of sedimentation.

The first step when designing an experiment is to clearly define the research question or objective that the experiment aims to address. This will help provide focus and direction for the experiment and guide the selection of variables, methods, and analysis techniques.

Everything in the earth is solid. But earth is not spherical. The earth has large holes that makes up the oceans.

Yes, there are several fault lines in Michigan, but they are not very active compared to other regions in the United States. The most notable fault line in Michigan is the Lake Michigan Fault. It does not produce frequent or significant seismic activity.

Relative Dating, its where the paleontologists date the fossils according to the layer of soil that the fossil was found compared to other fossils that were carbon dated that were in the same soil layer.

K2, the second-highest mountain in the world, was formed through the collision of the Indian and Eurasian tectonic plates. This collision caused intense folding and uplifting of the Earth's crust, leading to the formation of the Karakoram mountain range in the region where K2 is located. The mountain is primarily composed of sedimentary and metamorphic rocks that have been uplifted and eroded over millions of years.

Sudden covering of an organism with volcanic ash sediment will help preserve the organism from some normal decay mechanisms. Additionally, hard plant and bone may be replaced by silica from the ash over time, making the fossil resistant to erosion upon exposure at the surface. The Petrified Forest in Arizona would be an example of this process.

Although they usually traces of metals--like iron--in the clay they're made fro brick are not made of metal.

However as bricks are not composed of any single element but of compounds, they cannot properly be called nonmetals.

Silicate minerals are a group of minerals that contain oxygen and silicon as their primary constituents. Examples of silicate minerals include quartz, feldspar, mica, and amphibole. These minerals are the most abundant in the Earth's crust.

The Precambrian era is divided into three subdivisions: the Hadean, Archean, and Proterozoic eons. These subdivisions represent different stages in Earth's early history, from the formation of the planet to the evolution of complex life forms.

They can help us find information about how(if you believe so) we evolved.They also can track down when and where ancient organisms lived.(This dinosaur lived in this time, and that trilobite lived then)

Plants found in frigid zones include mosses, lichens, grasses, and small shrubs adapted to cold temperatures and short growing seasons. These plants are typically low-growing and hardy, able to survive in harsh conditions with minimal sunlight and nutrient availability. Examples include Arctic willow, Arctic poppy, and Arctic heather.

Chalcopyrite is an important copper ore mineral, commonly used in the production of copper due to its high copper content. It is also used as a source of sulfur in the production of sulfuric acid. Additionally, chalcopyrite has some industrial applications as a semiconductor material in electronics.

ANSWER: Mercury or quicksilver, is most commonly used in thermometers and barometers. It also has other scientific uses, such as manometers and float valves. Mercury is also used for medical purposes, such as blood pressure devices, and can be found in some over-the-counter medicine, such as eye drops, and diaper-rash ointment. Mercury is also used in mascara. Mercury's vaporous discharge can produce light, thus it can be found in some ultraviolet lamps. But, it can also be found in deposits all over the world, as cinnabar (Red mercury)
