It is approximately 5 1/2 miles (29000 ft or 9 km) thick

The troposphere extends about 7 miles (11 kilometers) above Earth's surface at the poles and about 12 miles (19 kilometers) at the equator.
The troposphere extends up to about 7 miles (11 kilometers) from the Earth's surface at the poles and up to about 10 miles (16 kilometers) at the equator.
The altitude of the bottom of the troposphere is around 8 kilometers (5 miles) at the poles and 18 kilometers (11 miles) at the equator. The altitude of the top of the troposphere is approximately 12 kilometers (7 miles) at the poles and 20 kilometers (12 miles) at the equator.
On average, the troposphere extends from the Earth's surface up to about 7 miles (11 kilometers) in the polar regions and up to about 10 miles (16 kilometers) in the tropical regions.
The stratosphere is typically about ten times thicker than the troposphere. It extends from about 10 to 50 kilometers above the Earth's surface, while the troposphere is only about 10-15 kilometers thick.
The troposphere is closest to Earth's surface. It is the lowest layer of Earth's atmosphere, extending from the surface up to about 10-15 kilometers. The stratosphere is located above the troposphere.
Troposphere
rad
The troposphere extends from the Earth's surface up to about 5 to 9 miles (8 to 14.5 kilometers) in the polar regions and up to about 11 miles (17.7 kilometers) at the equator.
The troposphere starts from the surface of the Earth until the it ends and goes into the stratosphere.
well there here are the layer in order: troposphere, stratosphere, mesosphere, thermosphere. the troposphere is about sixteen kilometers above sea level, so im guessing in about 2.5 seconds.
