Im pretty sure its composed of elements that are nonmetals. taking a test recently said that they were not noble gasses.
False. Air is mostly composed of nitrogen (about 78%) and oxygen (about 21%), with other gases like argon, carbon dioxide, and others making up the remaining 1%.
Continental polar is indicated by composed of cold dry air.
Mars' atmosphere is mostly composed of carbon dioxide (95.3%), with smaller amounts of nitrogen (2.7%) and argon (1.6%). There are also trace amounts of oxygen and water vapor in the atmosphere.
Rock - Earth is a rocky planet. In terms of chemical elements however, it is composed mostly of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminum (1.4%); with the remaining 1.2% consisting of trace amounts of other elements.
The air mass indicated by cold dry air is a continental polar air mass, designated as cP. This air mass originates over cold land regions and brings cold, dry conditions when it moves into other areas.
False. Air is mostly composed of nitrogen (about 78%) and oxygen (about 21%), with other gases like argon, carbon dioxide, and others making up the remaining 1%.
The brain is mostly composed of water, fat, and proteins.
Nitrogen is 80% of inhaled and exhaled air, but it is the 21% oxygen that body extracts from the air that allows us to efficiently metabolize the food we eat.
water
Wind is moving air. Air is mostly composed of the elements nitrogen and oxygen. Please see the link for information about the other elements in air.
is heterogenous because it is composed of many different gases. To be homogenous it would have to be composed of a single gas.
No, it is mostly composed in strophic and modified strophic forms.
A maritime polar air mass is composed of cold, moist air.
Mars has a thin atmosphere with low air pressure that is composed mostly of carbon dioxide. Its atmosphere is about 95% carbon dioxide, with very little oxygen compared to Earth.
The Battle of Britain was mostly an air battle.The Battle of Britain was mostly an air battle.
in our air is there mostly oxygen
