EES Meteorology - Layers & Composition

1. The BEST description of the troposphere is the layer of the atmosphere with the

• most ozone

• highest altitude

• greatest density

• coldest temperature

Which gas is represented by Gas #1?

• Oxygen

• Carbon dioxide

• Argon

• NItrogen

What layer does most weather occur in?

• mesosphere

• stratosphere

• thermosphere

• troposphere

What does the ozone layer do for us?

• It protects us from meteors

• It protects us from ultraviolet (UV) radiation by absorbing it

• It protects us from solar flares

• It does not help us at all

6. In which layer is the ozone layer found? Jet streams (fast-moving currents of air) also occur here.

• mesosphere

• stratosphere

• troposphere

• thermosphere

Which atmospheric layer is very hot and contains "light showers" known as auroras?

• stratosphere

• troposphere

• mesosphere

• thermosphere

Which layer is coldest? Meteors are also visible here.

• mesosphere

• stratosphere

• thermosphere

• troposphere

The layers of the atmosphere in order of INCREASING altitude:

• troposphere, stratosphere, mesosphere, thermosphere

• troposphere, mesosphere, atmosphere, thermosphere

• mesosphere, thermosphere, troposphere, stratosphere

• thermosphere, stratosphere, mesosphere, troposphere

Earth's current atmosphere is

• 78% nitrogen, 21% oxygen, 0.9% argon and 0.037% carbon dioxide

• 78% oxygen, 21%nitrogen, 0.9% argon, 0.037% carbon dioxide

• 78% nitrogen, 21% argon, 1% oxygen

• 78% oxygen, 21% nitrogen, 1% carbon dioxide

The layer of the atmosphere containing the ozone layer is

• troposphere
• stratosphere
• thermosphere
• mesosphere
