Miller and Urey modeled the conditions of Earth's early atmosphere by creating an experiment that simulated the atmosphere of primitive Earth. They used a mixture of gases like ammonia, methane, and water vapor, and subjected it to electrical discharges to simulate lightning. This experiment produced organic compounds, including amino acids, building blocks of life.
Miller and Urey's experiment used a mixture of gases including methane, ammonia, hydrogen, and water vapor to simulate the atmosphere of early Earth. These compounds were believed to represent the conditions present on Earth billions of years ago prior to the presence of oxygen.
Yes, scientists believe that a significant portion of Earth's early ocean water was formed from the condensation of water vapor in the primitive atmosphere, as well as from water-rich materials like comets and asteroids that collided with the planet during its formation.
volcanic activity releasing gases, like carbon dioxide, methane, and water vapor. Over time, these gases reacted with other elements on Earth, leading to the formation of a new atmosphere. Additionally, the capture of gases from comets and asteroids also contributed to the changing composition of Earth's early atmosphere.
Most scientists believe that Earth's early Archean atmosphere was formed primarily by gases released from volcanic activity. This included gases such as water vapor, carbon dioxide, nitrogen, and small amounts of methane. These gases were constantly being emitted by volcanic eruptions, shaping the composition of the atmosphere during that time.
The source of energy in the Miller-Urey experiment was a spark discharge, simulating lightning, which was used to provide energy to drive chemical reactions in their simulated early Earth atmosphere.
The electric spark in the experiment simulated the early conditions of Earth's atmosphere, particularly before the existence of life, and helped to create complex organic molecules that could eventually lead to the formation of simple life forms. This process is called abiogenesis or chemical evolution.

Stanley Miller and Harold Urey were two scientists who send electrical currents through gases that were believed to be Earth's early atmosphere (water vapor, ammonia, hydrogen, and methane). When the gases cooled, they thickened to make a salt water-like liquid that had things in it like amino acid, what is found in present-day cells.
The Miller-Urey experiment simulated the conditions of early Earth by creating a mixture of gases believed to be present in the atmosphere at that time, such as methane, ammonia, and water vapor. This mixture was then subjected to electrical sparks to mimic lightning, which was thought to have been a common occurrence on early Earth. The experiment resulted in the formation of organic molecules, including amino acids, which are the building blocks of life. This supported the hypothesis that the basic building blocks of life could have formed spontaneously on early Earth.

Urey and Miller published this experiment in the 50's and demonstrated that several small organic molecules could be formed under conditions believed to exist at the time when the earth was young.
there was no oxygen in Earth's early atmosphere.

The Miller and Urey experiment, while groundbreaking, has notable limitations. Firstly, it simulated early Earth conditions but may not accurately reflect the actual atmospheric composition or environmental factors of that time. Additionally, the experiment primarily produced amino acids, essential for life, but did not create more complex biological molecules or fully address how these molecules combined to form living organisms. Lastly, the experiment's reliance on specific conditions raises questions about the feasibility of such processes occurring naturally on early Earth.
