Weather Things: Atmosphere

Earth's atmosphere is thin compared to the planet's size. The troposphere, the lowest layer, is where weather occurs and is vital for life. It contains nitrogen, oxygen, and water vapor. Temperature and air pressure decrease with altitude, while wind increases. The stratosphere, above the troposphere, contains ozone that absorbs UV radiation. Beyond it are the mesosphere and thermosphere, which protect from solar radiation. The thermosphere is where the Aurora occurs, influenced by solar wind and Earth's magnetic field.

What is the primary composition of the troposphere?

• Mostly nitrogen and oxygen

• Mostly argon and neon

• Mostly hydrogen and helium

• Mostly carbon dioxide and methane

What happens to temperature as you ascend in the troposphere?

• It fluctuates randomly

• It decreases

• It remains constant

• It increases

What is a temperature inversion?

• An increase in temperature with height

• A decrease in temperature with height

• A random fluctuation in temperature

• A constant temperature with height

Which layer of the atmosphere contains the ozone that absorbs radiation?

• Thermosphere

• Mesosphere

• Stratosphere

• Troposphere

What is the primary function of the ozone layer in the stratosphere?

• To create weather patterns

• To produce oxygen

• To absorb ultraviolet radiation

• To trap heat

What natural phenomenon is produced in the thermosphere due to interactions with Earth's magnetic field?

• Thunderstorms

• Tornadoes

• Aurora

• Hurricanes

What is the potential impact of solar particles on technology?

• They have no impact

• They improve electrical power grids

• They disrupt GPS systems

• They enhance GPS accuracy
