Earth's first enduring atmosphere likely formed around 4.5 billion years ago from gases released during the planet's formation, such as hydrogen and helium. Volcanic activity also played a crucial role in shaping the early atmosphere, releasing gases like carbon dioxide, nitrogen, and water vapor. Over time, the Earth's atmosphere evolved through processes like photosynthesis and the formation of oceans, leading to the composition we have today.
What else can I help you with?
The first layer of the earths atmosphere touching earths surf?
The first layer of the Earth's atmosphere is called the troposphere, and it is in direct contact with the Earth's surface. This layer is where weather events occur and where most of the Earth's clouds and precipitation are found. Temperature usually decreases with altitude in the troposphere.
What is earths first layer of atmosphere called?
It's called lithosphere as I remember in science.
What was Earths first atmosphere was created by?
The earths first atmosphere was created by the methane, carbon dioxide, sulphur oxides and water vapor that volcanoes were pumping out. Oxygen started to come in noticeable quantities once life had formed. Nitrogen is inert, so doesn't do anything.
What is earths atmosphere is primarily composed of?

How thick is the earths atmosphere in kilometers?
The Earth's atmosphere is about 480 kilometers thick, with the majority of its mass concentrated within the first 11 kilometers (troposphere). The outermost layer, the exosphere, extends beyond 10,000 kilometers.
