What else can I help you with?
Earths atmosphere is defined as a layer of air that froms a?
It forms a blanket. A blanket of air.
Long streaks of bright light caused when a meteoroid gets close to the sun?
A meteor is long streak of light that is visible when a meteoroid gets close to the sun. When a meteor goes through the atmosphere and hits the ground, it is called a meteorite.
True or false there was a great deal of free oxygen in earths atmosphere before the first life forms developed?
false
When a meteoroid strikes the moon what forms?
Then a crater will be formed, depends a great deal on its size.
What essentials for life are found in earths atmosphere?
The Earth's atmosphere contains oxygen, which is essential for respiration in most living organisms. It also contains carbon dioxide, which plants use for photosynthesis to produce food. Water vapor in the atmosphere is essential for the water cycle, which is vital for all forms of life on Earth.
What gas became part of Earths atmosphere mainly as a result of the evolution of life-forms?
Oxygen became part of Earth's atmosphere mainly as a result of the evolution of life forms, particularly through photosynthesis by early cyanobacteria and plants. This process involved converting carbon dioxide into oxygen as a byproduct, leading to the oxygen-rich atmosphere we have today.
What is the difference between a comet asteroid meteor and meteorite?
Asteroids are made of rock or metal and are created in the inner, warmer solar system where as a meteor is had of ice, rock, and carbon-based compounds and are created in the colder, outer solar system.Another Take On ItThe primary difference between asteroids and meteoroids is size. They're made of the same stuff, but tradition in the science has held that asteroids are bigger in diameter than 10 meters, roughly 33 feet. Smaller hunks of rock, iron, ice, etc. that whiz around the sun are called meteoroids. _____________________________A "meteor" is the glowing streak of light in the sky caused by some object falling through the Earth's atmosphere and burning up. If the object survives and hits the Earth, it is called a "meteorite". Before it hits the atmosphere it may be a "meteoroid", or it may be something else.
Does radiowaves get through earths atmosphere?
Yes, radio waves can penetrate Earth's atmosphere. They are part of the electromagnetic spectrum and are able to pass through the atmosphere with minimal interference, which allows them to be used for various forms of communication, such as radio and television broadcasts.
What is earths Precambrian atmosphere?
The Earth's Precambrian atmosphere was primarily composed of carbon dioxide, methane, ammonia, and water vapor. It lacked oxygen and had higher levels of greenhouse gases compared to the present atmosphere. This environment supported the evolution of early life forms such as bacteria and algae.
Most moisture enters the atmosphere by the process of....?
...evaporation from bodies of water such as oceans, lakes, and rivers. This moisture then forms clouds through condensation and eventually falls back to the Earth as precipitation.
Did earths original atmosphere contain methane and ammonia?
Yes, Earth's original atmosphere is believed to have contained methane, ammonia, water vapor, and other gases. This atmosphere was formed from gases released during volcanic activity. Over time, the atmosphere changed due to the presence of early life forms that produced oxygen through photosynthesis.
What element does earths atmosphere has that no other planet has?
Earth's atmosphere contains a unique abundance of free oxygen, which is not found in significant quantities on any other planet in our solar system. This oxygen is produced mainly by photosynthesis from plants, making Earth's atmosphere distinct and supporting a wide variety of life forms.
