Layers of the Atmosphere Quiz Questions & Answer
Some common questions with their answer on layers of the atmosphere:
- What is layer closest to the Earth?
Answer: Troposphere.
- What is the layer above the troposphere?
Answer: Stratosphere.
- What is the layer above the stratosphere?
Answer: Mesosphere.
- What is the top layer above the mesosphere?
Answer: Thermosphere.
- How does the temperature variate in the four layers?
Answer: The way solar energy is absorbed as it moves downward through the atmosphere.
- What is the primary absorber of solar energy?
Answer: Earth's surface.
- What happens to the global average temperature in the troposphere altitude until the boundary between troposphere and stratosphere?
Answer: Decreases.
- What happens to the temperature in the altitude in the stratosphere?
Answer: Increases.
- What is the ozone layer?
Answer: Absorbing ultraviolet radiation from the sun.
- What does the ozone protect us from?
Answer: Sun's ultraviolet radiation.
- What can the sun's ultraviolet radiation cause?
Answer: Cancer, Genetic mutations, Sunburn.
- What is a human activity that contributes to the decrease in the stratospheric ozone?
Answer: Nitric oxide, exhaust of high-flying jets.
- What happens to the temperature at the stratosphere?
Answer: Stops increasing with altitude.
- What happens to the temperature at the mesosphere?
Answer: Decreases with altitude, does not absorb solar radiation.
- What happens to the temperature at the mesopause?
Answer: Begins to increase with altitude, and continues in thermosphere
- When does solar radiation first hit Earth's atmosphere and heats it?
Answer: Thermosphere
- What causes the temperature to increase with height through the stratosphere, and decrease with height through the mesosphere?
Answer: The temperature increases in the stratosphere due to ozone layer capturing ultraviolet radiation. The temperature decreases in the mesosphere since there is no ozone and the amount of air is decreasing.
- What causes the temperature to decrease with the height in the troposphere?
Answer: The farther away from the warm earth's surface we go, the less heat we feel until we hit the ozone layer in the stratosphere.
