Atmosphere Review 1

What are the thin layer of gases that surrounds Earth?

• altitude
• atmosphere
• climate
• ozone layer

Water in a gaseous form is called _________?

• condensation
• water vapor
• liquid
• gas

These gases are found in very little amounts in Earth's atmosphere. 

• Ozone Layer
• Trace Gases
• Carbon Dioxide
• Argon

This is the first layer of the atmosphere where oxygen is mostly found. Weather occurs here and is located at an altitude of 0-12 km.  

• Stratosphere
• Thermosphere
• Mesosphere
• Troposphere

This is the Second main layer of the atmosphere and is located at an altitude of about 12-50 km.  Some oxygen is found here along with ozone which protects us from harmful ultraviolet rays from the sun.  Planes also fly in this layer of the atmosphere. 

• Troposphere
• Thermosphere
• Stratosphere
• Mesosphere

The 4th main layer of the atmosphere is the hottest and thickest layer.  It absorbs most heat from the sun. There is also very little to no oxygen found here.  

• Troposphere
• Mesosphere
• Thermosphere
• Stratosphere

Which two gases are the most abundant gases in Earth's atmosphere? 

• Oxygen and Trace gases
• Nitrogen and Oxygen
• Carbon Dioxide and Oxygen
• Argon and Water Vapor 

This is the inner part of the Thermosphere. Ions (Electrical charges) are found here which bounces back to Earth.  This layer allows us to use cell phones, Instagram, Facebook, Skype among other things dealing with technology. Beautiful Auroras are found here. 

• Mesosphere
• Thermosphere
• Ionosphere
• Troposphere

This is the outer layer of the thermosphere. It referred to as outer space. 

• Troposphere
• Mesosphere
• Exosphere
• Ionosphere

This layer, found within the Stratosphere, protects Earth from harmful U.V. Rays from the sun. 

• Troposphere
• Mesosphere
• Ozone Layer
• Thermosphere
