This short quiz will ask you to answer multiple-choice questions on the timeline of the Earth's atmosphere. Ranging from 4.6 billion to 4 billion years ago, the name “Hadean” is a reference to the Hades, the Greek god of the underworld, and describes the hellish conditions present after the Earth’s initial formation.

A good introduction into the changes that have occurred with the Earths Atmosphere. A more recent video on the changing atmosphere of Earth. Share your story with the world. Collaborate with others like a Google Doc and share your story as a presentation. Oxygen is made by cyanobacteria (blue-green algae) as a product of photosynthesis. These gases may have consisted of hydrogen (H2), water vapor, methane (CH4) , and carbon oxides. About This Quiz & Worksheet. Save to favourites. This accumulation brought on many changes to Earth, and impacted future life irrefutably. 1. 1500 mya – Oxygen began to accumulate in the Earth’s atmosphere. Adding a photo to a place. Earth has had three atmospheres, each different in chemical composition. The atmosphere is the layer of gases that surrounds the Earth. The atmosphere is the layer of gases that surrounds the Earth. Adding Street View and a 3D view to a Google Earth project. Event(s) Early Atmosphere. An artist’s impression of the surface of Earth during the Hadean eon. 2. For 2,200 million years this oxygen was removed from the atmosphere as it reacted with iron, sank to the bottom of the sea and became trapped in rock layers.

Adding placemarks and lines to Google Earth. This atmosphere would have consisted of gases captured from the Sun - hydrogen, helium, ammonia, methane and water vapor - and resembled the atmospheres of … In the first 500 million years a dense atmosphere emerged from the vapor and gases that were expelled during degassing of the planet's interior. I find it very interesting to go back and go through the list from time to time :) Time Event 4.6 billion years: Share: … The oxygen that went on to occupy Earth's atmosphere (which was composed of methane, ammonia, carbon, and water vapor) was photosynthesized by stromatalites, or blue-green algae, that filled the oceans. Earth's first atmosphere started when the planet was formed, about 4.5 billion years ago, and lasted about 500 million years. Credit: T. Bertelink via WikiCommons CC BY-SA 4,0 The Hadean is the first geological eon of Earth’s history. All of the terrestrial planets - Mercury, Venus, Earth and Mars - had similar primary atmospheres.

Chemistry; The earth and its atmosphere; GCSE; Edexcel; Access full resource now . Evolution of the atmosphere - Evolution of the atmosphere - Sequence of events in the development of the atmosphere: If the planet grew large (and had, therefore, a substantial gravitational field) before all gases were dispersed from its orbit, it ought to have captured an atmosphere of nebular gases. The first of Earth's atmospheres, formed when the planet was still very young, was primarily hydrogen and helium.This atmosphere is about 4.57 billion years old, and was short-lived – heat from the molten crust and solar wind dissipated this layer. Timeline of life evolution on Planet Earth with approximate dates and events from when Earth first formed to modern human. This timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth.In biology, evolution is any change across successive generations in the heritable characteristics of biological populations. It has evolved over time and human activity is having an impact on the atmosphere. History Earth is believed to have formed about 5 billion years ago.

A great short video which simply explains the greenhouse effect and the possible problems that could occur. Today's Atmosphere. The first atmosphere on Earth, the primary atmosphere, appeared soon after the planet was formed, about 4.5 billion years ago. This atmosphere would have consisted of gases captured from the Sun - hydrogen, helium, ammonia, methane and water vapor - and resembled the atmospheres of the gas giants. Our planet has existed for 4.5 billion years, and it has been a busy few eons. It provides gases that are essential to life. What happened to the water vapour? Eccentricity: In a cycle of roughly 100,000 years, the shape of the Earth's orbit around the Sun varies from an almost perfect circle to a slightly more elliptical shape, with the Sun nearer one end (rather than in the middle), and then back to a more circular shape. I have been compiling this list for sometime now for my own curiosity.
