Question 54
MediumOriginal questionThe Earth wears a jacket. It is not made of cloth but of gases, and we call it the atmosphere.
This jacket does a great deal for us. It keeps the planet warm. It gives us the oxygen we breathe. And it is where all our weather happens, from a light to the heaviest monsoon rain.
The atmosphere wraps around the Earth rather like the peel around an orange. But unlike an orange peel, it is not the same all the way through. It is made of layers, each with its own , stretching from the ground all the way up to outer space.
Scientists name six of them. Closest to the ground is the troposphere, where we live and where the clouds and weather are. Above it come the stratosphere, the mesosphere and the thermosphere. The ionosphere with some of these higher layers, and last of all, away into space, is the exosphere.
The Earth is a good planet to live on for many reasons, and its atmosphere is one of the most important. Without that thin jacket of air, there would be no breath, no weather and no warmth.
"The ionosphere overlaps with some of these higher layers." This means the ionosphere
Show the answer and explanation
Correct answer: C
Explanation
To overlap is to cover part of the same area as something else.
So the ionosphere shares space with some of the higher layers rather than sitting neatly on its own.
Worth noting
The exosphere is the one described as "last of all".
