Educational worksheet illustrating Earth's atmospheric layers and their characteristics.

Since I can't view or access images directly, I’ll help you solve the task based on the description of the chart and the typical content related to Earth's atmospheric layers.

The table asks you to:

1. Draw a cube in the right-hand column that represents the density of air in each layer (the denser the air, the more "filled" the cube should be).
2. Draw pictures of objects found in each layer in the “Objects” column.
3. Fill in facts about each layer in the “Facts” column.

Let’s go through each layer from bottom to top (closest to Earth’s surface to outer space), and provide information for all three columns.

---

1. Troposphere

- Density: Most dense layer — draw a completely filled cube.
- Objects: Clouds, birds, airplanes, weather systems, rain, storms.
- Facts:
- The lowest layer of the atmosphere.
- Contains about 75–80% of the atmosphere’s mass.
- Where most weather occurs.
- Temperature decreases with altitude.

✔ *Cube*: Fully shaded (densest).

2. Stratosphere

- Density: Less dense than troposphere — draw a mostly filled cube, but not full.
- Objects: Ozone layer, jet aircraft, some high-altitude balloons.
- Facts:
- Contains the ozone layer, which absorbs UV radiation.
- Temperature increases with altitude due to ozone absorption.
- Very stable, no clouds or storms.

✔ *Cube*: ~75% filled.

3. Mesosphere

- Density: Much less dense — draw a lightly shaded cube.
- Objects: Meteors burn up here, some high-altitude research balloons.
- Facts:
- The coldest layer of the atmosphere.
- Temperature decreases with altitude.
- Meteoroids often burn up here due to friction.

✔ *Cube*: ~25% filled.

4. Thermosphere

- Density: Very low — draw a very lightly shaded cube (almost empty).
- Objects: Satellites (like the ISS), auroras (Northern/Southern Lights), meteors.
- Facts:
- Temperature increases rapidly with altitude (can reach over 1500°C).
- Air is extremely thin, so heat doesn’t transfer well.
- Home to the International Space Station (ISS).

✔ *Cube*: Almost empty (low density).

5. Ionosphere

- Note: This is not a separate layer but a region that overlaps the thermosphere and mesosphere (roughly from 60 km to 1000 km). It contains charged particles (ions) due to solar radiation.
- Density: Very low — same as thermosphere.
- Objects: Radio waves bounce off this layer, enabling long-distance communication; satellites.
- Facts:
- Ionized gases due to solar radiation.
- Important for radio communication.
- Includes the F-layer, E-layer, and D-layer.

✔ *Cube*: Very lightly shaded (same as thermosphere).

6. Exosphere

- Density: Extremely low — draw an empty cube.
- Objects: Satellites, escaping gas molecules (hydrogen and helium), space debris.
- Facts:
- Outermost layer of the atmosphere.
- Gradually merges with outer space.
- Particles are so far apart they may escape into space.

✔ *Cube*: Completely empty.

Summary Table (What You Should Draw)

| Earth's Layers | Objects | Facts | Cube Density |
|------------------|----------------------------------|------------------------------------------------------------------------|--------------|
| Exosphere | Satellites, escaping gases | Outermost layer; particles escape into space | ❏ (Empty) |
| Ionosphere | Satellites, radio waves | Charged particles; enables radio communication | ❏ (Very light) |
| Thermosphere | ISS, auroras, satellites | Very hot; thin air; temperature rises with altitude | ❏ (Light) |
| Mesosphere | Meteors, high-altitude balloons | Coldest layer; meteors burn up | ❏ (Medium) |
| Stratosphere | Ozone layer, jets | Contains ozone; temperature increases with altitude | ❏ (Full) |
| Troposphere | Clouds, birds, planes, storms | Weather occurs here; densest layer | ❏ (Fully filled) |

> 💡 Note: The Ionosphere is not a physical layer like the others but a region of ionized gas. It overlaps the upper mesosphere and thermosphere. So, it might be best placed within those layers rather than as a standalone one.

How to Draw:

- Use shading or filling in the cubes to represent density:
- Troposphere: Full black fill
- Stratosphere: ¾ filled
- Mesosphere: ¼ filled
- Thermosphere/Ionosphere: Light gray or minimal fill
- Exosphere: No fill

- In the Objects column, draw simple icons:
- Clouds and planes in Troposphere
- Ozone layer symbol or airplane in Stratosphere
- Meteor streaks in Mesosphere
- Satellite or aurora in Thermosphere
- Satellite and radio waves in Ionosphere
- Satellite or atoms floating in Exosphere
