How many feet tall is the atmosphere?

Answer 1

The atmosphere doesn't have a defined height, but it extends roughly 10,000 kilometers (about 6,200 miles) above the Earth's surface. Most of the atmosphere's mass, including the majority of weather phenomena, is concentrated within the first 10 to 15 kilometers (about 6 to 9 miles). The atmosphere gradually thins out with altitude, making the exact boundary somewhat ambiguous. The Kármán line, often used to define the boundary between Earth's atmosphere and outer space, is located at 100 kilometers (approximately 62 miles) above sea level.
