modern estimates suggest around 1 billion years but it could be less
The appearance of life on Earth increased the diversity and complexity of biological organisms, leading to the development of ecosystems and the formation of different habitats. It also contributed to the overall productivity and stability of the planet's biosphere.
T he appearance of moon regularly in different shapes. Also the day and night formation confirms the revolution of moon round the earth.
The major factors that rule out the co-formation theory for the Moon-Earth system include the difference in isotopic compositions between the Earth and Moon, the similarity in isotopic compositions between the Earth and Mars, and the angular momentum of the Earth-Moon system, which is not easily explained by the co-formation theory. Additionally, the giant impact hypothesis provides a more plausible explanation for the formation of the Moon.
Big Bang, formation of galaxies, formation of sun, formation of earth.
The metamorphism of limestone results in the formation of marble. Marble typically forms when limestone undergoes intense heat and pressure deep within the Earth, causing its minerals to recrystallize into a harder, denser rock with a distinct appearance.
Oxygen is believed not to be present at the time of Earth's formation.
Water on Earth was formed through a combination of processes including outgassing from the Earth's interior, delivery by comets and asteroids during the planet's formation, and reactions between hydrogen and oxygen in the atmosphere. The presence of water played a crucial role in shaping Earth's early environment and allowing for the development of life.
The repetitivity and revisit of satellite orbit refers to the time elapsed between observations of the same point on earth by a satellite. It usually depends with the target location, the orbit of the satellite and the swath of the sensor.
The fission theory is a scientific explanation for the formation of the Moon. It suggests that the Moon was once part of the Earth and broke off due to a massive impact with another celestial body, leading to its formation. This theory is supported by evidence such as the similarities in composition between the Earth and Moon.
