Earth's Atmosphere Worksheets

About These 15 Worksheets

Earth’s Atmosphere Worksheets are sets of questions and activities designed to help you learn about the invisible blanket of gases that wrap around our planet. This “blanket” plays a vital role in supporting life and influencing the weather. Worksheets provide a structured way for you to learn and test your knowledge on this topic.

Earth’s atmosphere is a fascinating and essential part of our world. It provides us with the air we breathe, protects us from harmful solar radiation, and regulates our planet’s temperature. These worksheets will help you understand the depth and breadth of this subject. From multiple-choice questions to creative activities, these worksheets offer various ways for you to engage with and understand the topic. The next time you step outside and take a deep breath, remember the amazing atmospheric system that makes that simple act possible!

The importance of this topic cannot be overstated, as it equips students with knowledge that is not only relevant to their daily lives but also critical for addressing global challenges like climate change and environmental conservation. By studying Earth’s atmosphere, students gain insights into the factors driving weather patterns, climate variations, and the consequences of human activities on our planet. Furthermore, this collection fosters scientific literacy, critical thinking, and an appreciation for the interconnectedness of Earth’s systems. Ultimately, it empowers students to make informed decisions about environmental issues and to become responsible stewards of the planet, contributing to a sustainable future.

What is Earth’s Atmosphere?

Earth’s atmosphere is a thin layer of gases that envelops our planet. It plays several crucial roles that make Earth hospitable for life as we know it. Let’s dive into its purpose and the various layers that make it up.


Provides Breathable Air – The atmosphere gives us oxygen to breathe and takes away carbon dioxide, which is a waste product of respiration.

Protection – It protects us from harmful ultraviolet (UV) radiation from the sun. The ozone layer, specifically, absorbs most of these rays.

Temperature Regulation – The atmosphere acts as a blanket, trapping some of the sun’s warmth, which is essential in keeping Earth’s temperatures stable and suitable for life. This is known as the greenhouse effect.

Meteoroid Protection – Small meteoroids often disintegrate in the atmosphere before they can reach the Earth’s surface.

Weather and Climate – It plays a central role in the water cycle, which includes processes like evaporation, condensation, and precipitation, thus influencing the weather and climate.

Layers of the Earth’s Atmosphere

1. Troposphere

Height – 0 to 8 km (at the poles) to 0 to 18 km (at the equator)

This layer is where we live, and it contains about 75% of the atmosphere’s mass and 99% of its water vapor. Weather phenomena like rain, snow, and storms occur here. The temperature decreases as you go higher in the troposphere.

2. Stratosphere

Height – About 8 to 50 km

The ozone layer, which absorbs and scatters the sun’s UV radiation, is in this layer. Interestingly, unlike the troposphere, the temperature increases as you move higher up in the stratosphere, primarily because of the ozone layer’s absorption of UV rays.

3. Mesosphere

Height – About 50 to 85 km

This is the coldest layer of our atmosphere, with temperatures falling as low as -90°C (-130°F). Most meteoroids burn up in the mesosphere, creating “shooting stars.”

4. Thermosphere

Height – About 85 to 600 km

This layer is characterized by high temperatures, which can climb thousands of degrees. However, if we were in the thermosphere, we would still feel cold due to the extremely low pressure and density. The auroras, Northern and Southern Lights, occur in this layer.

5. Exosphere

Height – Above 600 km

This is the outermost layer of our atmosphere, where atoms and molecules escape into space. The exosphere blends into the void of outer space and has very low density.
