What three dramatic events that changed the earth atmosphere?
Three dramatic events that changed the Earth's atmosphere include the Great Oxidation Event, which led to the buildup of oxygen around 2.4 billion years ago, the Chicxulub asteroid impact that caused the Cretaceous-Paleogene extinction event around 66 million years ago, and the eruption of the supervolcano Toba around 74,000 years ago, which caused a volcanic winter and significant climate change.
A change in Earth's total isolation would be caused by?
A change in Earth's total insulation can be caused by variations in the Sun's output, changes in Earth's orbit, or alterations in the composition of Earth's atmosphere such as increased greenhouse gas concentrations.
How can the atmosphere change the skies?
how can the atmosphere change the skies
What aurora borealis is caused by the blank which is a part of the atmosphere?
Charged particles from the Sun striking the upper atmosphere.
Auroras are caused by what hitting the atmosphere?
Auroras are caused by charged solar particles colliding with atoms of oxygen and nitrogen in the ionosphere, which is the highest level of the atmosphere.
What 1804 event caused the change?
napoleonic
What caused a major change in the composition of Earths atmosphere?
One major change in the composition of Earth's atmosphere was the Great Oxidation Event about 2.4 billion years ago. This event led to a significant increase in oxygen levels due to the emergence of photosynthetic organisms that released oxygen as a byproduct. This change had a profound impact on the evolution of life on Earth.
The atmosphere was filled with poisonous gases during the?
event and caused widespread illness and death among the population.
What change caused oxygen to build up in earth atmosphere?
the "invention" (or development) of chlorophil by plants

What oxidized metal caused substantial quantities of oxygen to accumulate in Earth's atmosphere?
Iron was the oxidized metal that caused substantial quantities of oxygen to accumulate in Earth's atmosphere, a process known as the Great Oxidation Event. This event occurred around 2.4 billion years ago as photosynthetic organisms began producing oxygen through photosynthesis, which reacted with iron in the oceans and rocks, leading to the buildup of oxygen in the atmosphere.
What caused te Earth's atmosphere to exist?
What caused the Earth's atmosphere to exist?
What process caused the atmosphere's composition to change so much?
Burning fossil fuel releases carbon dioxide, a greenhouse gas which is building up in the atmosphere.
What step caused an aerobic atmosphere during the history of earth?
The evolution of photosynthetic organisms, such as cyanobacteria, led to the buildup of oxygen in Earth's atmosphere through a process called the Great Oxidation Event. This occurred around 2.4 billion years ago, gradually transforming the atmosphere from anaerobic to aerobic.
