A layer of air that surrounds Earth to keep us warm is called

• atmosphere

• Sun's rays

• ozone layer

• air pressure

What protects Earth from ultraviolet rays from the sun?

• ozone layer

• mesosphere

• air pressure

• troposphere

In which temperature of air do the molecules spread out and take up more space?

• cold

• warm

In what layer would you find the ozone layer?

• troposphere
• stratosphere
• mesosphere
• thermosphere

What layer comes next:
Troposphere - 
stratosphere -
?????

• mesosphere
• exosphere
• thermosphere
• ionosphere

What gas makes up the majority of the atmosphere?

• oxygen

• nitrogen

• water vapor

• carbon dioxide

In what layer of the atmosphere would you find clouds and weather?

• troposphere
• stratosphere

• thermosphere

The layers of the atmosphere in order from bottom to top are

• troposphere, stratosphere, mesosphere, thermosphere, exosphere
• troposphere, mesosphere, atmosphere, thermosphere
• mesosphere, thermosphere, troposphere, stratosphere, exosphere
• thermosphere, stratosphere, mesosphere, troposphere, exosphere

The layer of the atmosphere containing our weather is

• thermosphere
• stratosphere
• troposphere
• mesosphere

The layers of the atmosphere that get colder as altitude increases are

• thermosphere and troposphere
• meosphere and troposphere
• stratosphere and thermosphere
• thermosphere and mesosphere
