Question

Scientists were motoring a meteor headed toward earth. It moved off course , but some pieces of rock entered the earths atmosphere . Which atmospheric layer protected the earth against the danger of the rocks ? A.the troposphere B.the stratosphere C.the mesosphere D.the thermosphere

Answer 1

The answer is C. The atmospheric layer that protects the Earth against danger of the rocks is the mesosphere. This layer is above the stratosphere. Meteors are rocks from the space that enter the atmosphere. Meteors burn as they go through the mesosphere layer. However, not all are completely burned some survives and still enter the Earth's surface. These are then called meteorites.

Answer 2

The correct option is C.

The atmosphere is made up of five different layers, which are: exosphere, thermosphere, mesosphere, stratosphere and troposhere. The farthest layer is the exosphere while the nearest one to the earth surface is the troposphere. Each of these layers have their specific functions. The mesosphere is the one that is responsible for protecting the earth surface from meteors and asteroids. The mesosphere functions by burning up the greater parts of these substances before they enter the earth surface.
