Frage 136

When a meteor strikes the Earth’s atmosphere, a linear ionized region is formed at what region of the ionosphere?

  1. The E regionRichtige Antwort
  2. The F1 region
  3. The F2 region
  4. The D region

Erklärung

Meteoroids ablate and ionize the air at roughly 80 to 120 km altitude, which is E-region height, leaving a column of free electrons behind the particle. The F1 and F2 regions lie far higher, above about 150 km, and the D region lies mostly below the meteor ablation zone.
