Educational worksheet for students to identify and label the layers of Earth's atmosphere.

Explanation:
We need to list the layers of Earth’s atmosphere from bottom to top (i.e., starting closest to Earth’s surface and going upward into space).

Here are the five main layers, in order from the ground upward:

1. Troposphere – This is where we live and where weather happens. It’s the lowest layer.
2. Stratosphere – Above the troposphere; contains the ozone layer.
3. Mesosphere – Where meteors burn up (“shooting stars”).
4. Thermosphere – Very hot layer; auroras happen here; the International Space Station orbits in this layer.
5. Exosphere – The outermost layer, fading into space.

So the correct order (bottom → top) is:
Troposphere → Stratosphere → Mesosphere → Thermosphere → Exosphere

Now, looking at the worksheet: there are 5 blank boxes above Earth, and we need to label them from bottom (closest to Earth) to top (farthest). That means:

- Bottom box (1st): Troposphere
- 2nd: Stratosphere
- 3rd: Mesosphere
- 4th: Thermosphere
- Top box (5th): Exosphere

Let’s double-check:
✔ Troposphere — yes, lowest
✔ Stratosphere — above troposphere
✔ Mesosphere — above stratosphere
✔ Thermosphere — above mesosphere
✔ Exosphere — highest, merges with space

All correct.

Final Answer:
Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
