Atmosphere
The atmosphere is a layer of gases surrounding the Earth. It is held in place by the force of gravity and is vital for supporting life on Earth.
Composition of the Atmosphere
The atmosphere is composed of several gases, with the most abundant being:
- Nitrogen (78%)
- Oxygen (21%)
- Argon (0.93%)
- Carbon dioxide (0.04%)
Other gases such as water vapor, methane, and ozone are also present in smaller amounts.
Layers of the Atmosphere
The atmosphere is divided into several layers:
- Troposphere: The layer closest to the Earth's surface where weather occurs.
- Stratosphere: Contains the ozone layer which absorbs UV radiation.
- Mesosphere: Where meteors burn up upon entering the atmosphere.
- Thermosphere: Contains the ionosphere where auroras occur.
- Exosphere: The outermost layer where the atmosphere transitions into space.
Functions of the Atmosphere
The atmosphere serves several important functions:
- Protects the Earth from the sun's harmful radiation
- Regulates the Earth's temperature
- Supports life by providing oxygen for respiration
- Drives weather patterns and the water cycle
Study Guide
Here are some key points to remember about the atmosphere:
- What are the primary gases in the Earth's atmosphere?
- What are the layers of the atmosphere and their characteristics?
- What are the functions of the atmosphere?
Understanding the atmosphere is important for understanding weather patterns, climate change, and the overall functioning of our planet. It's a fascinating topic that connects to many other areas of science and environmental studies.

PHYSICAL SCIENCE
Motion and Stability: Forces and Interactions
Investigate the resulting motion of objects when forces of different strengths and directions act upon them (e.g., object being pushed, object being pulled, two objects colliding).
Use observations and data from investigations to determine if a design solution (e.g., designing a ramp to increase the speed of an object in order to move a stationary object) solves the problem of using force to change the speed or direction of an object.
LIFE SCIENCE
Ecosystems: Interactions, Energy, and Dynamics
Distinguish between living and nonliving things and verify what living things need to survive (e.g., animals needing food, water, and air; plants needing nutrients, water, sunlight, and air).
