Miller and Urey modeled the conditions of Earth's early atmosphere by recreating a mixture of gases believed to be present during that time period, such as methane, ammonia, hydrogen, and water vapor. They then subjected this mixture to electric sparks to simulate lightning, which resulted in the formation of simple organic compounds like amino acids, the building blocks of life.

How did miller and Urey model the conditions in earth's early atmosphere?

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.


What compounds were used in Miller and Urey's experiment to simulate the atmosphere of early Earth?

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.


What created earths early atmosphere?

Earth's early atmosphere was created by gases released from volcanic activity, such as water vapor, carbon dioxide, nitrogen, and small amounts of methane. Over time, the atmosphere evolved through processes like photosynthesis by early organisms, which contributed oxygen and transformed the composition of the atmosphere to what it is today.


Which important element was missing in earths early atmosohere?

Oxygen was the important element missing in Earth's early atmosphere. It was only produced later by photosynthetic organisms.


Earths early atmosphere was changed dramatically by the evolution of?

photosynthetic organisms, like cyanobacteria, which produced oxygen as a byproduct of photosynthesis. This led to the increase in atmospheric oxygen levels, changing the composition of Earth's early atmosphere.
