Volcanoes played a significant role in shaping the early Earth's atmosphere by releasing various gases through volcanic eruptions. Some of the key gases emitted by volcanoes that contributed to the formation of the early atmosphere include:
Water Vapor (H2O): Volcanic eruptions released large amounts of water vapor into the atmosphere. Water vapor is a greenhouse gas that can trap heat, contributing to the planet's warming.
Carbon Dioxide (CO2): Volcanoes emitted substantial quantities of carbon dioxide, which is another greenhouse gas. CO2 in the atmosphere helped trap heat and played a vital role in regulating the early Earth's temperature.
Nitrogen (N2): Nitrogen gas was released by volcanoes in smaller amounts compared to water vapor and carbon dioxide. Nitrogen is a non-reactive gas that makes up a significant portion of Earth's modern atmosphere.
Methane (CH4): While not as abundant as other gases, methane was also released by volcanoes. Methane is another greenhouse gas that can influence the climate by trapping heat.
Sulfur Dioxide (SO2): Volcanic eruptions produced sulfur dioxide, which can react with water vapor in the atmosphere to form sulfuric acid (H2SO4). This contributed to the acidity of early rainfall.
Hydrogen (H2): Hydrogen gas was emitted by volcanic activity, and it may have played a role in the chemical evolution of Earth's early atmosphere.
Ammonia (NH3): Ammonia was likely present in trace amounts in the volcanic emissions, although it played a relatively minor role compared to other gases.
It's important to note that the composition of the early Earth's atmosphere evolved over time due to various geological and biological processes. The gradual accumulation of oxygen (O2) in the atmosphere, for example, was the result of photosynthesis by early photosynthetic organisms. This oxygenation of the atmosphere occurred over billions of years and had a profound impact on the development of life on Earth.

genetic engineering
volcanic eruptions
the Panama Canal
plate tectonics
Answer:
Option (2)
Explanation:
Genetic engineering is defined as a process by which a DNA (or other molecules of nucleic acid) can be artificially operated, alter and recombined so that an organism can be modified. In addition to this, modification of gene and cloning can also be done. This a human-operated system.
Genetic engineering is directly based on the study of a DNA, which is present inside the body of an organism, so it is considered as a human system.
Hoover Dam and the Panama canal are both human-made structures. Plate tectonics is a geological process that leads to the eruption of volcanoes and is a natural process.
Thus, the correct answer is option (2).
The human systems among the given options are genetic engineering, the Panama Canal, and plate tectonics.
The human systems among the given options are genetic engineering, the Panama Canal, and plate tectonics.
Genetic engineering is the manipulation of an organism's genes to produce desired traits or outcomes.The Panama Canal is a human-made waterway that connects the Atlantic and Pacific Oceans, allowing for easier trade and transportation. Plate tectonics is the scientific theory that explains how Earth's lithosphere is divided into several large plates that move and interact with each other, which indirectly affects human life through earthquakes and volcanic activity.
