Gases are lighter than solids and liquids, so light that they can be in our atmosphere. Example, when water evaporates it is light and goes up into our atmosphere where it will condense to form liquid, which is now heavier and more dense and therefore falls
Earth's gravity is what holds all the gases in the atmosphere around the planet. Gravity exerts a force that prevents the gases from escaping into space, creating the atmosphere that surrounds the Earth.
The gases surrounding the Earth or any astronomical body is called the atmosphere.
The Earth's atmosphere consists of all the gases that surround the planet, such as nitrogen, oxygen, carbon dioxide, and others.
Gases are evenly distributed throughout all levels of the atmosphere due to the process of diffusion. This means that gases move from areas of high concentration to areas of low concentration, resulting in a relatively uniform distribution of gases in the atmosphere.
Chemicals can be both ozone depleting and greenhouse gases depending on their chemical structure and how they interact with the atmosphere. For example, certain chlorofluorocarbons (CFCs) can deplete the ozone layer by breaking down ozone molecules, while also acting as powerful greenhouse gases by trapping heat in the atmosphere. The dual impact of these chemicals highlights the complex interplay between different environmental issues.
no they don't.
I wouldn't say that many chemicals occur naturally in the air, however Oxygen and Nitrogen are the two main gases that make up the Earth's atmosphere.
An atmosphere.
carbon
The atmosphere itself is NOT an element. The atmosphere is a mixture of all the gases around the planet. Some gases are elements, but because there is more than one gas in the atmosphere, it is a MIXTURE of elements not an element itself.
It depends on the chemical and its strength. The majority of 'chemicals' are harmless and are connected to various odors, scents, or aromas that you find in the everyday world. Many chemicals that are artificially made or that are used as solvents can be extremely hazardous to health. Of course, many chemicals are made deliberately to be poisonous.
The greenhouse effect warms the gases in the atmosphere.
