What is the correct sequence of layers of the atmosphere from innermost to outermost?

• mesosphere-stratosphere-thermosphere-troposphere

• troposphere-stratosphere-mesosphere-thermosphere

• stratosphere-thermosphere-troposphere-mesosphere

why is ozone important to life on Earth?

• it destroys carbon dioxide

• it absorbs the sun's U.V. rays

• it is an important part of the Thermosphere

• it helps to control the population on Earth

• convection

• conduction

• radiation

• electricity
