Troposphere - Wikipedia
The troposphere is the lowest layer of the atmosphere of Earth. It contains 80% of the total mass of the planetary atmosphere and 99% of the total mass of water vapor and aerosols, and is where most weather phenomena occur. [1] .

The Troposphere - Center for Science Education
The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.

Layers of the Atmosphere - National Oceanic and Atmospheric Administration
Troposphere. Known as the lower atmosphere, almost all weather occurs in this region. The troposphere begins at the Earth's surface, but the height of the troposphere varies. It is 11-12 miles (18-20 km) high at the equator, 5½ miles (9 km) at 50°N and 50°S, and just under four miles (6 km) high at the poles.

Troposphere | NASA Space Place – NASA Science for Kids
What is the troposphere? The troposphere is the innermost layer of Earth’s atmosphere. Closest to the surface of Earth, we have the troposphere. “Tropos” means change. This layer gets its name from the weather that is constantly changing and mixing up the gases in this part of our atmosphere.

What Is the Troposphere? - Earth How
What Is the Troposphere? The troposphere is the lowest layer of the Earth’s atmosphere. It extends to about 20 km (12 miles) above the Earth’s surface. The air pressure in this layer decreases as altitude increases. This causes the troposphere to have a significant influence on weather conditions.

Troposphere - an overview | ScienceDirect Topics
The troposphere (free of charged particles) is the lowermost region of the earth’s atmosphere whereas the ionosphere extends over an altitude range of 50–1000 km and consists of sufficient ionization (ions and electrons) to refract the radio waves.

What Is the Troposphere? - Characteristics, Importance - thedailyECO
The troposphere is the closest atmospheric layer to Earth, stretching from the planet's surface to an elevation of about 10 kilometers (6 miles). This crucial layer encompasses roughly 75% of the Earth's atmosphere, holding nearly all of its precious water vapor.

Troposphere | Weather, Climate Change & Air Pollution | Britannica
Troposphere, lowest region of the atmosphere, bounded by the Earth beneath and the stratosphere above, with its upper boundary being the tropopause, about 10–18 km (6–11 miles) above the Earth’s surface. The troposphere is characterized by decreasing temperature with height and is distinguished.
