The early Universe basically only consisted of hydrogen, and small amounts of helium. Heavier elements were created in the center of stars - these materials got into space, mainly through supernova explosions, and became part of newer solar systems.

Name four systems that the Earth belongs?

The Earth is part of the solar system, which includes the sun and other planets. It also belongs to the Milky Way galaxy, one of billions of galaxies in the universe. The Earth is part of the geosphere, biosphere, and hydrosphere that make up its interconnected natural systems.


If Earths biosphere were younger we would have oxygen in the atmosphere?

Not necessarily. The presence of oxygen in Earth's atmosphere is the result of biological processes that have occurred over billions of years, not simply a function of the biosphere's age. Other factors such as the balance of oxygen-producing and oxygen-consuming organisms also play a role in determining atmospheric oxygen levels.


Is the hydrosphere a living thing?

yes b/c hydrosphere is all the water in the world and there is a lot of marine/ocean life ranging from the blue whale to plankton (not spongebob -_-) so yeah there is life in the hydrosphere. go h2o!


What was the primary factor missing of billions of years that was necessary for protists to evolve?

The primary factor that was missing for billions of years that was necessary for protists to evolve was oxygen in the atmosphere. Billions of years ago, the atmosphere was mostly made up of carbon dioxide, carbon monoxide, hydrogen, nitrogen, and water vapor.

How much has the earth change over time?

The Earth has changed significantly over billions of years due to geological processes such as plate tectonics, climate fluctuations, and the evolution of life forms. These changes have shaped the planet's surface, atmosphere, and ecosystems, leading to the diverse environments we see today.


What is the original biosphere?

The original biosphere refers to the Earth's natural and balanced ecosystem before significant human alteration. It includes all living organisms and their interactions, as well as the physical environment that supports life. This system has evolved over billions of years into a complex and interconnected web of life.


What was the primary factor missing for billions of years that was necessary for protists to evolve?

The primary factor missing for billions of years was the presence of oxygen in the Earth's atmosphere. The evolution of protists and other complex life forms was made possible by the emergence of photosynthetic organisms like cyanobacteria, which produced oxygen as a byproduct of photosynthesis. This oxygenation of the atmosphere allowed for the development of aerobic respiration in organisms, enabling more complex metabolic processes to evolve.


Starting billions of years ago algae lowered the?

...lowered the level of CO2 in the atmosphere and released O2


Seas could not form billions of years ago until?

The atmosphere relieved itself of moisture in the form of rain.


The primary source of earths atmosphere is?

The primary source of Earth's atmosphere is outgassing from volcanic activity and the release of gases from Earth's interior. This process began billions of years ago and continues to contribute to the composition of our atmosphere.
