What is the Thermosphere?

The thermosphere is the fourth layer of the Earth's atmosphere, located above the mesosphere and below the exosphere. It extends from about 80 kilometers (50 miles) above the Earth's surface to the edge of space, approximately 500 kilometers (310 miles) above the Earth.

Characteristics of the Thermosphere

The thermosphere is known for its extremely high temperatures, which can reach up to 2,500°C (4,500°F) during the day. However, despite the high temperatures, the thermosphere would not feel hot to our bodies because the air density is so low.

This layer is also where the International Space Station orbits, and it is where the northern and southern lights, or auroras, occur.

Importance of the Thermosphere

The thermosphere plays a crucial role in protecting the Earth from the sun's harmful ultraviolet (UV) and X-ray radiation. The molecules in the thermosphere absorb these high-energy rays, preventing them from reaching the Earth's surface and causing harm to living organisms.

Study Tips for the Thermosphere

The resources above cover the following skills:

Geometry (NCTM)

Specify locations and describe spatial relationships using coordinate geometry and other representational systems.

Use coordinate geometry to represent and examine the properties of geometric shapes.

Use coordinate geometry to examine special geometric shapes, such as regular polygons or those with pairs of parallel or perpendicular sides.

Use visualization, spatial reasoning, and geometric modeling to solve problems.

Use geometric models to represent and explain numerical and algebraic relationships.

Measurement (NCTM)

Apply appropriate techniques, tools, and formulas to determine measurements.

Select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision.

Connections to the Grade 6 Focal Points (NCTM)

Measurement and Geometry: Problems that involve areas and volumes, calling on students to find areas or volumes from lengths or to find lengths from volumes or areas and lengths, are especially appropriate. These problems extend the students' work in grade 5 on area and volume and provide a context for applying new work with equations.
