Paleontology

The atmospheric conditions during the Moseozoic Era were a warm, moist feel. This type of condition was needed for the gargantuan herbivores to survive. If it was not like this, the Era would most likely be vague and abnormal to us homo-sapiens

Scientists study airflow so that they can better understand it, the air flow can also help with determining the weather. Some scientists also study airflow so we can create better and more efficient cars and transportation.

The percentage of oxygen in air remains fairly constant on a global scale but varies considerably on a local scale. The concentration of oxygen in your lungs is much different as you inhale than when you exhale for example. The concentration of oxygen entering your car's engine is much different than the concentration in the exhaust from that same engine.

The percentage remains fairly constant on a macroscopic scale because of the equilibrium established by the uptake by plants of the carbon dioxide and subsequent release of oxygen through photosynthesis. There is also a substantial amount of oxygen dissolved into the oceans of the Earth which remains in equilibrium with the oxygen in the air. Just based on the scale, it would take an enormous amount of oxygen addition or removal from the atmosphere to make a significant change in the percentage of oxygen in the atmosphere. Such a change would take a very long time to accomplish. In truth, the composition of the atmosphere millions of years ago was different than now - with noticeably higher levels at times and lower levels at other times. It took millions of years for the changes to occur however.

Travelers in the Ordovician time period might face dangers from marine predators such as giant sea scorpions and armored jawless fish. They might also encounter environmental hazards like widespread glaciation and unpredictable shifts in sea levels. Additionally, volcanic activity and tectonic movements could pose risks to travelers during this time.

Can you define more clearly what you mean by 'Strongest'? That can cover a vast number of different categories and there are many different metals which can be considered the strongest, according to your specification.

You should be careful when you find a fossil because they are often fragile and can easily break if mishandled. It's important to handle fossils gently and with care to preserve them for future study and enjoyment. Additionally, some fossils may contain sharp edges or delicate structures that can be easily damaged.

There are two major schools of thought that can provide two entirely different answers to this subject. See the discussion section below for a Creationist's point of view on this answer.

Anyone knowing the current scientific answer to this can feel free to finish off this answer.

When living things die, sometimes they can get buried in mud or sand before they rot away. If this happens, over time the mud or sand can be turned into rock and the hard parts of the living things are also mineralized (turned into rock) but in a way that preserves the structure of the original living thing.

An impression of a living thing preserved in this way is called a fossil and by studying the fossils that are to be found in rocks it is possible to see and understand creatures that lived on earth a very long time ago.

It's happening right now. The human race has or is about to wipe out as many species as the meteorite that hit the planet 65 million years ago and ended the reign of the dinosaurs, which was about 90% of all life on earth.

1. Preservation in sedimentary rock: The organism's remains are buried in sediment and mineralized over time.
2. Casts and molds: The organism's remains decay, leaving an impression in the sediment that is later filled with minerals.
3. Carbonization: The organism's remains are compressed, leaving behind a thin film of carbon.
4. Freezing or desiccation: The organism is preserved through freezing or drying out quickly.
5. Amber preservation: The organism becomes trapped in tree resin, preserving it over time.

Drywall, also known as gypsum board or plasterboard, is a home-building material made primarily from the mineral gypsum. Gypsum is processed and compressed between two sheets of paper to create drywall panels commonly used for interior walls and ceilings in buildings.

Gabbro is usually made up of minerals such as pyroxene, plagioclase, amphibole and olivine which makes it an intrusive igneous rock.

Temperate forests are located in the eastern parts of North America and Asia as well as central and Western Europe. The temperature in these forests fluctuates from -30 degrees Celsius to 30 degrees Celsius.

It was the second largest extinction in terms of loss of life. The extinction was caused by the movement of Gondwana into the south polar region which led to glaciation and subsequent sea level fall. At this time all know life was confined to the oceans and 60% of marine invertebrates died. The event ended when Gondwana moved out of the south polar region, the glaciers melted, and sea level returned to normal.

The main type of rock in oceanic crust is basalt. Basalt is a fine-grained igneous rock formed from the rapid cooling of lava at or near the Earth's surface. It is dark in color and rich in minerals like pyroxene and plagioclase feldspar.

They are valuable because they are rare and take a long time to process to create a good looking stone. They are classified as "gemstones".

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.
