Earth's atmosphere likely formed from gases released during volcanic activity and comet impacts, rather than solely from icy planetesimals. Processes like outgassing from the Earth's interior and chemical reactions between the surface and incoming cosmic debris played significant roles in shaping the composition of our atmosphere over time.

Why is the earths surface not covered by the same impact craters?
First, we have a nice thick atmosphere that deals with many meteors. Secondly, weathering and erosion erase the marks fairly quickly.
A round pit on the earths surface?
That would likely be a crater, caused by an impact from a meteorite, asteroid, or volcanic activity. Craters can vary in size and shape depending on the force of the impact.
What is a true statement about the moon?
The moon is Earth's natural satellite, orbiting around our planet. It has a significant influence on Earth's tides due to its gravitational force. The moon's surface is covered in impact craters and lava plains, and it has no atmosphere.
What is a rock from space that strikes earths surface?
A rock from space that strikes Earth's surface is called a meteorite. When a meteoroid (a small rocky or metallic body) enters Earth's atmosphere and survives the journey to impact the surface, it is termed a meteorite.
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.
What impact does earths atmosphere have on humans?
Lots.
Why are cartels rare?
cartels are formed by the impact of falling object from space. since most of the objects disintegrate into fragments on or before entering the earths atmosphere it do not make any noticeable impact. hence cartels are rare.

Features of earths moon?
Impact craters.
What sudden event could change the earths atmosphere?
A massive volcanic eruption or asteroid impact could release significant amounts of dust and gases into the atmosphere, potentially causing a rapid and substantial shift in atmospheric composition.
How does severe weather in Earths atmosphere affect Earths geosphere?
Severe weather in Earth's atmosphere can lead to erosion and weathering of the Earth's geosphere. This can cause changes in landforms, such as landslides or mudslides, as well as sediment transport and deposition. Additionally, strong winds and precipitation can impact the stability of the geosphere, potentially triggering geological hazards like earthquakes or volcanic eruptions.
Who has the greatest impact on the temperature of the Earths atmosphere?
Human activities, particularly the burning of fossil fuels and deforestation, have the greatest impact on the temperature of the Earth's atmosphere. These activities release greenhouse gases, such as carbon dioxide, into the atmosphere, which trap heat and lead to global warming. Other factors, such as natural variability and solar radiation, also influence the Earth's temperature but human activities are the primary driver of current climate change.
What is the impact of an earthquake on the Earth's atmosphere?
Earthquakes do not have a direct impact on the atmosphere. An earthquake only damages the Earth and structures on the Earth.
What becomes of the asteroids that falls into the earth atmosphere on the surface of earth?
An asteroid is generally a significantly large mass of matter. When such an object enters the earths atmosphere they are called meteors. Most burn up in the atmosphere. If they reach the surface then they are called meteorites. Many, many thousands do so but are tiny and cause little or no damage. As the earths surface is about 70% water most fall into seas and oceans. A relatively large body would cause massive damage if it hit a populated location. Such things have happened but rarely so. It is likely that such an event happened about 65 million years ago which resulted in the extinction of the dinosaurs. An example of such an impact can be seen in Arizona at the Barringer crater which is estimated to have happened about 50 thousand years ago.
Why is the atmosphere most vulnerable part of the earths environment?
Many people today assume mistakenly that the Earth is so big that we humans cannot possibly have any major impact on the way our planet's ecological system operates.
What caused the impact crater in Arizona US?
The Barringer Crater resulted from a meteorite impact with the earth about 50,000 years ago.
What happens to asteroids when they enter the earths atmosphere?
When asteroids enter Earth's atmosphere, they start to burn up due to friction with air molecules. This causes them to create a bright streak known as a meteor or shooting star. If they are large enough to survive the entry, they may impact the ground as meteorites.
