The lowest layers, where the air is denser. Air pressure - and density - decrease by 1/2 every 5 kilometers or so, meaning that half of the mass of air is in the first 5 km above sea level (this reasoning makes the simplifying assumption that the Earth has no differences in elevation).
The troposphere is the layer of the atmosphere that contains most of the atmosphere's total mass. It is the layer where weather occurs and where most of Earth's air is found.

The Mantle
The troposphere is the most abundant layer in Earth's atmosphere. It is where most weather phenomena occur and contains about 75% of the atmosphere's mass.
The troposphere is the layer of the atmosphere closest to the Earth's surface and contains around 75% of the total mass of the atmosphere. This layer is where most weather phenomena occur and where we find the air we breathe.
The most of the mass of atmosphere is contained in troposphere. It contains most gases.
The mantle and core make up the most percentage of Earth's mass. The mantle is the thickest layer and accounts for about 84% of Earth's total volume, while the core makes up about 32.5% of Earth's total mass.
The layer closest to the Earth's surface is the troposphere. It contains most of the atmosphere's mass and is where weather events occur.
The layer that constitutes most of the total mass in the atmosphere is the troposphere. This lowest layer extends from the Earth's surface up to about 8 to 15 kilometers (5 to 9 miles) high, depending on geographical location and weather conditions. The troposphere contains approximately 75% of the atmosphere's mass and is where most weather phenomena occur. Its density decreases with altitude, but it holds the majority of the air's molecules.
