Where is crust located?
The Earth's crust is the outermost layer of the Earth. It is divided into two types: continental crust, which forms the continents, and oceanic crust, which forms the ocean floors.
How did the first person come on earth?
The first person on Earth would have come about through evolution from simpler life forms over millions of years. This process of evolution led to the development of complex organisms, eventually leading to the emergence of modern humans.
Who were the first to live on earth?
The first life forms on Earth were single-celled organisms such as bacteria and archaea that appeared around 3.5 billion years ago. These simple life forms evolved into more complex organisms over time.
The layer where organisms can exist on the surface of the earth?
Organisms can exist on the surface of the earth in the biosphere, which includes all regions of land, water, and air where living organisms are found. The biosphere is where plants, animals, and other life forms interact with each other and with their physical environment.
What would happen to earth if the greenhouse effect did not exist?
If the greenhouse effect did not exist, Earth would be much colder than it is now, with an average temperature of about -18°C (-0.4°F). This would make the planet uninhabitable for most forms of life. The greenhouse effect plays a critical role in trapping heat from the Sun and maintaining Earth's temperature within a range suitable for life.
Is it possible for non carbon-based life forms to exist on Earth?
While carbon-based life forms are the most common on Earth, it is theoretically possible for non carbon-based life forms to exist. However, there is currently no evidence of such life forms on our planet.
How many years did earth exist before there was evidence of life on?
Earth is estimated to be around 4.6 billion years old, and evidence of the first life forms dates back to about 3.5 billion years ago, in the form of fossilized microorganisms. This means there were around 1.1 billion years of Earth's existence before evidence of life appeared.
Where have Scientists discovered that life forms on Earth exist?
Life has been found just about anywhere on Earth.
Would plants or animals have been the first forms of life on earth?
Unicellular plants and animals were first forms of life on Earth
What were the first life forms to inhabit the earth?
Plants
What is the specific name of the one organism on earth that does not use oxygen it its respiratory system?
There exist several life forms which do not need oxygen for survival, for example bacteria purple sulfur bacteria (Chromatiales). But if I recall correctly, no higher life forms which don't need oxygen exist on Earth.
What did people do when the earth first exsisted?
Some people believe the earth was first created 4.6 billion years ago, humans did not exist, nor did any other life forms. Humans didn't come into being until 15 million years ago, about 4.45 billion year's into earth's history.
Which single-celled organism is most closely related to the first cell to exist on your planet?
The single-celled organism that is most closely related to the first cell to exist on Earth is likely a type of archaea. Archaea are ancient single-celled microorganisms that are considered to be one of the earliest life forms on our planet. They share many genetic and biochemical similarities with the first cells that appeared on Earth.
Do other life forms exist outside earth?
I think so. It's not scientifically proven, but you never know...
What was earth's first life forms?
bacteria is not right it is prokaryotes
Does life exist inside the core of our Earth?
No. It is too hot, but life does exist in caves and there is a wide range of what can be found from the smallest bacteria to the largest bat.add. By and large, life forms require water and water below 100 deg C. And that rather limits the possibility of life forms in the interior of the Earth.
What is a contribution of anaximander?
he made the first map,he is also a geologist,,,he accurately deduced that there had been other forms of life on earth million of years before man
