7th Grade-Atmosphere

What percent of our atmosphere is made up of gases other than oxygen and nitrogen.

• 5%
• 1%
• 2%
• 10%

Instruments used to measure air pressure are called

• thermometers
• hygrometers
• hydrometers
• barometers

As you rise upwards in the atmosphere, air pressure

• increases
• decreases
• doesn't change
• first increases, then decreases

The layer of our atmosphere is which weather occurs is the

• troposphere
• stratosphere
• mesosphere
• exosphere

The greenhouse effect is

• the absorption of energy by clouds
• a gradual increase in the temperature of the atmosphere
• the reflection of solar energy into the atmosphere
• the process by which gases hold heat in the atmosphere

Local winds differ from global winds because they

• are cause by unequal heating within a small area
• are caused by differences in cloud cover
• are due to unequal rain
• are not influenced by air masses

Earth's rotation makes global winds curve.  This is called the 

• convection effect
• global effect
• Coriolis effect
• rotational effect

From earth to space, the main layers if our atmosphere are

• troposphere, stratosphere, mesosphere, thermosphere
• stratosphere, troposphere, mesosphere, thermosphere
• mesosphere, troposphere, stratosphere, thermosphere
• thermosphere, troposphere, stratosphere, mesosphere

The lowest layer of the atmosphere is

• troposphere
• stratosphere
• mesosphere
• thermosphere

The ozone layer, the layer that protects us from the sun's rays is found it

• troposphere
• stratosphere
• mesosphere
• thermosphere
