Quizplus · Accepted Answer

Earth's atmosphere extends only a few hundred kilometers above its surface, so satellites that orbit more than 100 km up are above most of Earth's atmosphere. This is important because the atmosphere can interfere with satellite signals and drag on the spacecraft, causing it to lose altitude over time. Additionally, being above the atmosphere allows for clearer and more accurate observations of Earth's surface and space.
