Questions and Answers

Why don't meteors burn in the Thermosphere?

  • Because the air density is high and there is much friction
  • Because the meteors are made of a special heat-resistant material
  • Because the air density is low and there is not much friction (correct)
  • Because they are already burnt out by the time they reach the Thermosphere

    • What happens to the temperature as you go up in the Thermosphere?

  • It gets colder
  • It becomes unpredictable
  • It gets hotter (correct)
  • It stays the same

    • Why is the Thermosphere the hottest layer of the atmosphere?

  • Because it has the highest air pressure
  • Because it absorbs the most solar radiation from the sun (correct)
  • Because it is the closest to the Earth's surface
  • Because it has the lowest air density

    Study Notes

    Meteor Behavior

    • Meteors don't burn in the Thermosphere due to low air density and minimal friction.

    Thermosphere Characteristics

    • Temperature increases as you go up in the Thermosphere.
    • The Thermosphere is the hottest layer of the atmosphere, absorbing the most solar radiation from the sun.
    • This is because there is almost no gas (only 0.1%) to protect the Earth from the sun's radiation.

    Auroras

    • Auroras form when solar storms from the sun interact with the Earth's magnetic field, releasing ionizing gas.
    • This gas travels to the north and south poles, producing the blue and green colors we see.
    • Auroras form in the Thermosphere.

    Ionosphere Composition

    • The Ionosphere is composed of electrically charged particles.

    Spacecraft and Satellites

    • Spacecraft and satellites are not placed beyond the Thermosphere because they are too high for gravity to pull them back.
    • They may get lost in space after burning all their fuel.

    Atmospheric Layers

    • The percentage of gases in each layer of the atmosphere is: • Troposphere: 75% • Stratosphere: 19% • Mesosphere: 5.9% • Thermosphere: 0.1% • Exosphere: No gases

    Star Properties

    • The color of a star indicates its temperature, with white stars being the hottest.

    Sky Appearance

    • The sky appears blue when seen from Earth's surface because blue light scatters the least as sunlight travels through the atmosphere.

    Space Junk

    • Space junk is formed by humans and consists of broken or discarded pieces of satellites, rockets, and other objects orbiting the Earth.
