Timeline of Photosynthesis on Earth - Scientific American

Dr Iain Stewart explains how volcanic activity on the early Earth may have played an important role in the emergence of life about four billion years ago. He visits hot springs in Rotorua, New Zealand, to meet Dr Bruce Mountain, who explains the theory.

Timeline of The Earth by on Prezi

Due to tidal acceleration, the distance of the Moon from the Earth has been increasing by approximately 3.8cm each year. By 600 million AD, the distance has increased by nearly 23,000 km. At the same time, the Sun has been growing in size by a significant amount.

A cloud of super-heated dust, ash and steam would spread from the crater, as the impactor burrowed underground in less than a second. Excavated material and pieces of the impactor – ejected out of the atmosphere by the blast – would be heated to incandescence upon re-entry, broiling the Earth's surface and igniting global wildfires. Meanwhile, colossal shock waves would spawn global earthquakes and volcanic eruptions. The emission of dust and particles would cover the entire surface of the Earth for several years, possibly a decade, creating a harsh environment for living things to survive. The shock production of carbon dioxide caused by the destruction of carbonate rocks would trigger a sudden greenhouse effect.

The Sun's luminosity has increased by 10%, causing Earth's surface temperatures to reach an average of 47°C (116°F). As the seas and oceans begin to evaporate, the atmosphere is becoming laden with water vapour, creating an intense greenhouse effect. Mars is actually becoming more habitable during this time.

However, these satellites would fall back to Earth eventually. LAGEOS-1 was predicted to re-enter the atmosphere in 8,400,000 AD. It contained a plaque, designed to allow future descendants of humans to view the arrangement of Earth's continents in the past, present and future.

Pioneer 11 is the sister craft of Pioneer 10. Launched in 1973, it completed a successful flyby of Saturn in 1979, before heading out to interstellar space, travelling in the opposite direction of Pioneer 10. After four million years, it passes by Lambda Aquilae, a blue-white B-type main sequence dwarf star, around 125 light years from Earth. Like its sister, Pioneer 11 carries a plaque with a message from humankind.

the energy necessary for life on Earth

Purely biological (non-cyborg) humans are exceedingly rare now. The very few which do remain comprise only a tiny fraction of the total sentient minds in existence. Though free to come and go as they please, they have practically zero influence in any governmental systems on Earth or elsewhere, being regarded as wholly subordinate to AIs and other entities. As a species, homo sapiens has continued to evolve over time. This has led to a further increase in cranial size, a near-total absence of hair, an elongation of limbs, a more robust and capable immune system, and increased lifespan.

The Timeline of the Earth by Anna Zmistowski on Prezi

The Earth's surface and seas contained great quantities of iron that readily combined with oxygen to produce iron oxides. From the beginning of the Proterozoic Eonto 1.85 Ga, atmospheric oxygen levels rose as the rate of photosynthesis increased considerably. Shallow seas became partially oxygenated but the deep oceans continued to be anoxic. Although photosynthetic organisms had been releasing oxygen since Archean times,the oxygen levels could not build up in the atmosphere because the oxygen was beingdepleted by the oxidation of metals andby the oxidation of methane to yield carbon dioxide and water in the presence of ultraviolet (UV) radiation.

Earth's third atmosphere (Proterozoic Eon, 2.5 to 0.54 Ga)
Monocellular life proliferated during the Proterozoic Eon. Anaerobic microbial lifethrived in a planet with little oxygen. Anaerobic organisms obtained their energy in various ways. Methanogens combined hydrogen and carbon dioxide to produce methaneand water:

Toward the end of the Hadean Eon, volcanic activity started increasing thepercentage of carbon dioxide in the atmosphere. The Earth's surface changed from molten lava to solid rock, and liquid water started to accumulate on the surface.
