The troposphere contains 75 percent of atmosphere's mass- on an average day the weight of the molecules in the air is14.7 lb..(sq. in.)- and most of the atmosphere's water vapor.
Gravity. It tends to pull air downward.

Hydrogen
Hydrogen. Actually the figure is closer to73.46% hydrogen. 24.85% is helium.
Hydrogen gas is the predominant element of the sun, accounting for some 74% of its mass, and 92% of its volume.
If there was no troposphere, all weather events on Earth would cease. The troposphere contains roughly 75 percent of the atmosphere's mass.
Gravity. It tends to pull air downward.

Troposphere is name of the layer. It contains 75 percent of the air.

There are a few layers to the atmosphere however the Troposphere is the largest part of the atmosphere containing 75% of its mass. However the Troposphere contains 99% of the water vapour on the planet as well as Earth's aerosols. It is also where all weather phenomenon will occur.
Most of earth's atmosphere is in the lowest layer, the troposphere. Thus most of the gases are within 15 km of the Earth's surface.
because its closest to earth
It is the lowest section of our atmosphere, with an avg. depth of 11km (7miles). Contains 75% of atmosphere's mass.
The troposphere is the layer closest to the Earth.
