A. Troposphere
B. Stratosphere
C. Ozone layer
D. Ionosphere
Check Answer
The correct answer is D. Ionosphere.
The ionosphere is a layer of the Earth’s atmosphere that extends from about 60 kilometers (37 miles) to 1,000 kilometers (620 miles) above the Earth’s surface. It is named for the presence of ions, which are electrically charged particles that are formed when high-energy solar radiation ionizes the atmospheric gases in this region. The ionosphere is responsible for reflecting radio waves back to the Earth’s surface, allowing for long-distance radio communication. This is because the ionosphere has varying degrees of ionization at different altitudes, which can reflect different frequencies of radio waves back to the Earth’s surface.
